NEXT MEETING: Monday, June 28th, 2010

The Albuquerque Gem & Mineral Club meets on the 4th Monday of the month. All meetings are held at the New Mexico Museum of Natural History, 1801 Mountain Road NW in Old Town, Albuquerque, New Mexico. The entrance is on 18th Street. The meeting begins at 7:30 p.m. in the Sandia Room on the 2nd floor. There is a short business meeting prior to the evening’s presentation, which begins at approximately 8:00 p.m. The Junior Club meets at 6:30.

 

 

GENERAL MEETING FEATURED PRESENTATION

"Finding, Value and Processing of Baker Eggs"

by Fred Hurd and Chris Cowan

To make up for missing what would have been a very interesting program at last month’s cancelled meeting, the program for June offers double the fun, with two friendly, familiar faces presenting a program they premiered last November at the New Mexico Mineral Symposium. Fred Hurd is a school administrator in Las Cruces, and Chris Cowan is a freelance digger from the same area. Although both are acknowledged experts in the mineral field, they also share a passion for pretty rocks with stripes – and despite all the wonderful banded agates found around New Mexico, to the world at large our reputation rides on Baker eggs. These products of the Hermanas region down by the bootheel have unique colors and forms, making them among the most prized thundereggs worldwide. Fred and Chris will amaze the eye with tantalizing photos of some of the best agate you’ve ever seen, while they educate

mazed… and don’t forget to thank Bruce Owens, V.P. of Programs, for arranging all the wonderful speakers we’ve enjoyed this year.

 

President’s Message

The Meeting That Didn't Happen

Here is what happened to the best that I have been able to sort it out. There was a power outage at the Natural History Museum around 10:00 a.m. on the day of our May general meeting and all staff members were sent home for the day. As soon as we checked our phone messages at 3:00 p.m. we sent e-mails to all club members that the meeting was cancelled. A few people e-mailed that they had not checked their e-mail before going to the meeting only to see a sign on the door that the AGMC meeting was cancelled, but that there were a lot of people having some sort of convention/meeting.

It seems that power was restored around 4:30 p.m. but the museum's staff who schedules our meetings didn't think it was "prudent" to let us know. The Bureau of Land Management (BLM) had their symposium that evening as scheduled. Apparently different people were responsible for scheduling the BLM event and they had a different idea of the "prudent" way to handle the situation.

Actually it probably all worked out for the best because a week previously we had been moved to our old meeting room down stairs in order to make room for the BLM event. This would have meant that our general meeting would immediately follow the Junior Club meeting in the same room requiring a complete meeting setup being done in short order. And we would have been quite crowded if the normal number of members showed up.

My biggest regret about the whole mess was that our speaker for that evening drove 600 miles to be here. We went ahead and paid her the honoraria to help offset her expenses.

Here's to trying again in June,

Jay Penn

May Field Trip Report

May 15-16, 2010 Field Trip

Tarryall Mountains near Lake George, CO

A dozen or so intrepid AGMC members made the trek to the Tarryall Mountains near Lake George, CO for a two-day trip in search of topaz, amazonite and smoky quartz on the claims of our hosts for the weekend, Donna Ware and Jeff Self. The Friday commute from Albuquerque was a rain and snow mix that had all us wondering what the heck we were doing going to the high country. Most of the group car camped, while others stayed in nearby Woodland Park. The sun returned on Saturday, along with spectacular Rocky Mountain views. Eager AGMC collectors were joined by a few members of the Colorado Mineral Society.

Donna and Jeff shared samples of the local topaz and showed us some potential pegmatite seams to bust into to find pockets of the gemstones. They have had much success on their claims and were very gracious to invite us and to show us some of their techniques. We all dug, chiseled, swung hammers, scratched through promising gravel piles, and otherwise moved a lot of rock and dirt looking for the fine glassy clear topaz. Some chips were found and lots of great quartz crystals were discovered, but no real topaz bonanzas were unearthed this particular day.

On day two, the group relocated deeper into the mountains to the Crystal Peak region accessible from Divide, CO. Sunday’s mission was to collect amazonite and smoky quartz. The beautiful blue-green mineral amazonite was plentiful on the surface and in dumps. Many ambitious club members dug in search of even deeper blue and finer specimens. A couple of yard rocks probably made the trip back to Albuquerque too.

I think that all club members that went this time around had a great time and would like to say a big AGMC thanks to our hosts. Donna and Jeff have expressed interest in having AGMC members back next May for another round of camping and collecting.

July Field Trip and Club Picnic

San Pedro Mine, near Golden, NM

 

     The July field trip and picnic will be at the San Pedro Mine located near the intersection of NM 14 and NM 344 about 30 minutes from Albuquerque.

     Mine owners Frank and Sally Baca are allowing us to rock hound and picnic on their property without any limit to the number of club members allowed to attend. This is a privately owned mine and therefore we must adhere to the owners’ instructions about where, when, and how much we collect and otherwise conduct ourselves.

     One stipulation is that we stick together as a group. The property is behind locked gates and once we enter, the gates will be re-locked until the field trip is over. Don't be late!!

     Pets will not be allowed. There is no age limit for children attending, however all children will need to be properly attended at all times and not allowed to roam at will.

     Ray DeMark will be our interpretive speaker during the mine tour. We will have a limited collecting time and then break for our picnic.

(Trip leaders’ note:  In the past the AGMC has lost the privilege of collecting at this desirable site due to members who wouldn't

follow the rules. Our field trip VPs and other club members have worked hard to secure us another chance; please don't blow it. The AGMC Collecting Ethics for Private Claims are listed on the club website and are in the new member's package.) 

     WHEN AND WHERE: Take 1-40 east, exit 175 @ Tijeras Canyon, take Rt. 14 north towards Golden. It's a 30 - 45 min. drive. We'll meet in a large open area at the SE corner of NM 14 and NM 344 at 8:00. Waiver sheets will be filled out and collected at this time. At 08:30 we will depart to the gated mine property entrance. Don’t be late!

     FOR COLLECTING: Bring the usual tools; pick, bucket, newspaper to wrap specimens, small spade/shovel, safety glasses, WATER, sunscreen, hat, gloves. In July the rattlers are slithering and mountain lions have been seen in the area in the last several years. Just be alert!! We suggest boots and long pants. You may want to bring shade or your camera. We will be carpooling with 4WD vehicles.

     COLLECTING POSSIBILITIES: Garnets, pyrite, quartz, calcite, malachite, and many other different specimens. Iridescent garnets are frequently found and much sought after.

     Around 1:00 we'll head back down for our picnic. Bring your own picnic basket, place settings, chairs, etc.  There is a building we can use to get out of the sun but if you prefer sitting outside bring an awning for shade. A single porta-potty will be at the picnic site for our use. The club will provide drinks, ice and cups. I believe Gwen Poe plans to have an ice cream making session so plan on taking a turn or two at the crank. The last time this was great stuff.

      To add to the fun during the picnic, we will have a Members’ Tailgate Sale. Bring your rocks, minerals, gems, tools, etc., and money, to sell/trade/buy/show.  Or as Amy says, "Let's have a grand time!"

Rex Nelson

 

About the picnic

     There’s more to a picnic than the date or the food!

     Get ready; July 24th will be a terrific day because we will be together.

     Bring your own food basket. AGMC will provide drinks, ice, and cups. I will prep two (2) ice cream makers and will need helpers with the handles.

     Bring a whistle, a blanket, a chair, a game, and an umbrella if you want to. This is in addition to your collecting gear.

Thanks, Gwen

August Member Field Trip Notice


Morenci Copper Mine Tour:

AGMC has a group reservation for 9:00 a.m. on Saturday, August 14 for a tour of the Freeport-McMoRan Morenci Copper Mine, one of the largest open pit copper mines in the world. The Morenci Mine is located in Greenlee County in eastern Arizona, approximately a six- hour drive from Albuquerque. We will rendezvous at the Morenci Motel, 261 Burro Alley, Morenci AZ 85540 at 8:30 a.m. so we can all pay our tour fees, sign waivers, and otherwise get organized for our tour and short collecting opportunity. Please see alternate Field Trip at the end of this article.

Advance Club RSVP and making room reservations:

Please call Brian Anderson at 573-8872 or e-mail at osodad@comcast.net to confirm your interest in going on the tour. Reservations are required for the Morenci Mine Tour and I will provide them an approximate head count by

July 30 so we can get the appropriate size bus for our group. I have a couple of different driving routes suggested through Mapquest.

AGMC members will responsible for their own tour fees: Children (9-17, 8 or younger cannot go on the tour) are $4.00, Adults $8.00 and Seniors (65+) are $7.00. There are 29 rooms at the Morenci Motel with rates ranging from

$62.60 to $79.58 (kitchenette) for singles and $67.90 for doubles. To make room reservations call the Morenci Motel at (928) 865-4111. The Mine Tour info line is (877) 646-TOUR (8687).

Tour Description:

"Copper Guides" will welcome us at the Morenci Motel near the motel's front desk. There is a restaurant and gift shop on the premises. Before beginning the tour, we’ll be briefed about the tour itinerary and given an overview of copper and the high-tech mining processes used at Morenci. The orientation also will cover safety while on the tour.

After the briefing, we will board our climate-controlled tour bus and head out on the tour for about 2-1/2 hours. Spectacular lookout points will enable us to experience the enormity of the operation. At each stop we will see first hand the various steps in taking the raw ore from the ground to the finished pure copper. And along the way, our guide will keep us informed, intrigued and entertained with copper "did you knows," information about the mine and its fascinating history.


Appropriate Attire:

Shoes must have a closed toe. You will not be permitted on the tour if you are not wearing closed toe shoes. Shirts with sleeves are recommended. Because this is an outdoor experience, we suggest you check the prevailing seasonal weather conditions and dress accordingly.

Collecting:

At Morenci a low grade porphyry copper ore is mined. Actually it is a combination of chrysocolla, chalcopyrite, and chalcocite. Chrysocolla is a copper silicate mineral, while chalcocite and chalcopyrite are copper sulfides. By-products of the mine are silver, gold and molybdenum. As part of the tour AGMC members can collect copper minerals from a large shovel dumped. Collecting will be early in the tour and will last approximately a half-hour dependent on blasting at the mine. There is a one-bucket limit. Standard tools should be okay, though smaller army shovels and more compact gear fits better on the bus.


A few other interesting Morenci facts…

• The Morenci Mine is North America's leading producer of copper.

Arizona produces more copper than any other state in the nation.

The Morenci Mine at peak production can move more than 800,000 tons of rock each day and can produce 850 million pounds of copper each year.

• The equipment is mammoth. One $2 million haul truck can carry 270 tons of ore on tires almost 12 feet in diameter.

Alternate "Plan B" Field Trip, Section 21 Mine in the Zuni Mountains:

The Morenci Mine Tours are in the process of hiring new drivers and guides and are currently not giving tours. They anticipate being operational in July or August. A final determination will be made next month whether to postpone this field trip. Our back-up field trip will be on the same day to the Section 21 Mine in the Zuni Mountains to collect fluorite. AGMC members will be kept updated.

Co-leaders:

Brian Anderson & Suzanne Seymour

AGMC This Month

Mama’s Minerals and

Southwestern Minerals

Special thanks are due to Mama’s Minerals for their extra donation from the show. I think most of you saw the geode cracking "booth" at the show this year. That booth was arranged for and staffed by folks from Mama’s Mineral’s. After subtracting the costs of the materials and salaries for the workers, there was $200 left over so Mama’s sent us a check for that amount! Mama’s has also been very generous with donations for our raffles, etc. They have always been highly supportive of our club and show.

I also need to mention that Southwestern Minerals has been a staunch supporter of the club and show for many years. I believe that only a few of you know that the AGMC stores most of the paraphernalia for the show in Southwestern’s warehouse for a very nominal fee.

Thanks to both and I hope that all of our members patronize these establishments to show our appreciation.

Junior Club in June

For the June meeting we will discuss gold, gold panning, and gold mining. I will set up a gold panning station where the juniors can try their hand at separating "gold" from sand and rocks with a gold pan. Earlene is going to discuss the different ways gold is mined and extracted from the resulting ore.

The rockhounds in the group will have an experiment dealing with what minerals may contain and how to test them.

See you at the meeting---

A Long Long Time Ago in AGMC

June 1980 News Nuggets

Why the Watermelon Mountains?

By Pete Modreski (AGMC President 1977 & 1978)

What is the origin of the name, Sandia Mountains? It’s well known that sandia is Spanish for watermelon, but exactly why was this name given to the mountain range? I have always heard and accepted the story that the name is for the way the west face of the mountains, with its red (especially at sunset) granite and fringe of green forest at the top, resembles the center and rind of a watermelon. This seems to make sense; however, as is often the case with names, several other possible explanations exist.

"New Mexico Place Names" by T.M. Pearce (University of New Mexico Press, l975) says that the first recorded use of the name Sandia was in the name of a Franciscan convent, San Francisco de Sandia, mentioned by Fray Alonso de Benavides in his Revised Memorial of l634. The convent was located in the "principal pueblo of the Tiwa Indians," which we now

know as Sandia Pueblo. The convent was supposedly given this name because, "Tradition has it that watermelons grew abundantly in the canyons of the mountains near the pueblo or in the pueblo itself." True watermelons, as opposed to squash, pumpkins or wild gourds, were not native to the southwest but were presumably introduced by the Spanish. Pearce notes that the original Tiwa name of the pueblo was na-fi-at, "dusty place", and that the Tiwa name for the mountain itself was o-ku-piu, "turtle mountain". It would seem that "Sandia" was perhaps first used in the name of the convent, then for the pueblo and for the mountain.

Rockhounding – My Personal Thoughts

Part 2

By John Scully

Don’t Peck, Dig!!

So, you have explored the area and found the most likely spots. Now what?? My answer is "dig!!" Many rockhounds just peck away at a spot. They neither have the tools nor the inclination to really dig. But many many times the indicator you have found is just the tip of the proverbial iceberg. Often, it leads to more and better material within the earth, and you have to get it. I have a reputation as an aggressive digger, but I also find lots and lots of specimens. Move as much dirt and rock as you can, being careful not to move wonderful specimens unseen with it. A tip: dig down!! Most people dig in and up when they find a worthwhile place. In just a little time, they cover up the base of the dig, and when it gives out, they give up. Take the time to excavate down from where they were digging and you might find some real treasures, including new material or beauties that a too-eager person missed.


A full array of tools is essential. For digging, breaking and moving lots of material, you will need a pick axe, shovel (hand and full size), chisels, pry bars from small to full length (5 feet), and hand and full sized sledges. I use a 12 pounder. My friend Rex carries a 20 pounder in his truck. Try hefting one of those. For lighter work, once you have found a seam or vug of specimens: geology hammers (a long handled one for digging and prying and a small "lady’s" one for trimming), light chisels, trowels, screw drivers, whisk brushes, spray bottle. Did I mention gloves? Always wear gloves.


Some uses of the lighter tools: While digging furiously to locate specimen bearing rock or dirt, be ready in an instant to stop and do some fine work. Use the trowel, whisk brush and spray bottle to reveal what is under the coating of dirt. Once you have seen indicators in the dirt, sit down and become an archaeologist with your trowel, carefully and slowly going through the accumulated pile that you have dug. If you find a likely piece based on odd shape or hint of color, whisk it off or spray it with water. If it is a piece of layered material showing promise in its seams, gently pry it open with the screwdriver. If you’ve found an area of vugs which would be destroyed with your hammer or chisel, gently probe with the screwdriver. Carry a loupe to examine likely specimens for smaller but possible rarer minerals.   Carry these lighter tools while conducting the initial exploration along with water, first aid supplies, food, a GPS and whatever else you need for a walkabout in the wilderness.  And, don’t be afraid of rock. It may seem awfully solid, but most rock has fractures in it which you can exploit. If you see any at all, take a chisel and sledge to it. If you see no fractures at all, hit it with an 8 or 12 pounder a few times. That will reveal any cracks, which you can now exploit with the chisel. Besides, all of this work is good for you. Hiking all over the place and moving a ton of earth is healthy. My wife Laurie loves the feel of my biceps when I return from a week of heavy earth moving.


Estwing carries a wide array of tools which are very durable. I also include my 4WD Toyota Tacoma as a tool. New Mexico is so big and rugged that a 4WD is required to reach the large majority of places you might want to explore.


Of course, always wrap your specimens in newspaper, paper towels or toilet paper and safely stow them in a box. Old beer cases are excellent. I prefer cheap plastic tubs from Walmart. Part of digging is minimizing damage to the location. If you are digging in the dumps or side of an old mine, this is not too important. You are just moving dirt from one part to a lower part. But, in pristine woods or desert, you can leave an ugly hole. Fill it back up when you leave, and try not to move too much of the natural vegetation.

Safety
All of the above activity requires major and continuous safety precautions. Did I say always wear gloves? It is incredibly easy to injure your hands. Here are other thoughts:

When in rugged territory, which much of NM is, always use a GPS to locate your starting point in a walk about. The GPS will always get you back to your truck. Carry extra batteries.

When using a sledge or hammer, be sure to wear glasses or safety goggles. In addition to this, when I am pounding away, I have trained my self to close my eyes and mouth with every blow. When using a heavy sledge (12 pounder), I bow my head just before the blow hits the rock. This size sledge can send some huge fragments into an exposed tooth or through your glasses. Also, continually clean fragments from the spot that you are hitting with the sledge.

When using a small sledge (3 or 4 pounder) and chisel, always use a chisel with a safety bib. You may hit 999 out of 1000 blows successfully, but the 1 of a thousand can destroy your hand. Did I say always wear gloves???

Be awfully careful using pry bars. You can kill or seriously injure yourself putting maximum pressure on a bar only to have it suddenly give way hurling you backwards into whatever you have thoughtlessly ignored behind you

Always and continually survey the surrounding rock. Even a small one coming down a slope can seriously hurt you. A slightly larger one can kill you. When you start digging, assess the potential for anything on a slope above you to give way and fall. Remove any thing that seems obvious. Continuously survey around and above you to see if small cracks have opened up in the dirt or rock. This is a sign that you are undermining and loosening material that can collapse on you. Either get out immediately or dig out the loosening material. Hit the rock with a hammer – if it is loose, it will move or sound hollow and you will know to be very careful. Even the most careful digger cannot predict rock 100% successfully. I learned this when first in NM digging at a fluorite claim. The rock next to me was a solid as one could ever imagine, except that it wasn’t. I was widening a hole into a tube when a section of the wall the size of a small car let loose, kissed my elbow and fell away. Six inches more and I would have had half my body removed. The seemingly solid wall held this block by a tiny seam of selenite which gave way with my sledge pounding. I wrote a poem that night:

Death Visited Today

Death visited today.

Her breath kissed my elbow

as she flew by swiftly

and landed at my feet.

Though it was not the time

for death my life to seek,

to me it’s awfully clear

that she came for a peek.

Was it to give warning?

Or, just plain happenstance?

Well, the simple truth is,

that living’s full of chance.

Her peek did not cause fright,

neither, melancholy.

But, God’s sunset that night

was the best I have seen.

When moving large rocks or hunks of dirt, always imagine which way it might move when released and get out of the way. If there is any doubt about its path, move well away and use a long pry bar to release it.

Use a dust mask when digging in highly dusty or toxic circumstances. For example, our fluorite claim is full of lead dust. A dust mask is also advisable when cleaning specimens with a high power water gun such as the Arrow spot remover.

When driving back roads, never take your 4WD into locations that you cannot turn around in or successfully traverse. On really rugged roads, where you cannot continually see places ahead in which to turn around, get out and scout ahead on foot.

Don’t go underground into mines unless you are with someone and unless you are certain that it is safe. If you do, wear a hard had with plenty of light and back up batteries. Generally, don’t go into underground mines at all.

Beware of critters. There are many snakes in NM as well as scorpions. Never put foot or hand in a place you have not seen. I’ve unearthed as many as 20 scorpions in a day’s digging. Did I say always wear gloves?

Camping


Earlier, I mentioned that spending plenty of time to explore is essential. In New Mexico, which is so huge, the only way to do this is usually to camp out at the location you are exploring. Since you can’t haul a camper down most of our back roads, you have to camp in a tent or truck. I prefer the truck because I have the illusion that I will be safe from the state’s many bears and cougars. So far so good. Without going into detail, let me simply say that one can camp comfortably out of and in one’s truck for days on end. In my case, the exceptions are temps below 20 degrees, high wind which is howling right now as we speak and NM’s toxic no-seeums.
OK, I convinced myself. I will do a follow on article about truck camping while exploring. The sheer beauty of this state is overwhelming. If you couldn’t care less about a rock, you’d have to love camping here. Listen to Garth Brook’s Night Rider’s Lament, or read any Louis L’Amour novel to know what I mean. Have you ever seen an endless column of elk slowly bugle past you a hundred yards away? Seen stars and the Milky Way so close you could simply scoop them up with your hands? Heard the coyotes call? Seen eagles screeching above? Climbed endless peaks and valleys? Watched our sunrises and sunsets? If not, you need to be here.

This article is dedicated to people like my friend Rex Nelson and his kind who have been prospecting this state for over 30 years, and is one of the genuine rockhounds and prospectors in the country.

A few folks emailed me that they read the Mystery Mineral and try to decipher the mineral names. Email me at paulhlava@q.com and let me know your guesses by copying the Questions below and answering them. This includes AGMC members and everyone else who reads "News Nuggets". I have gotten very few responses, folks. EMAIL me at paulhlava@q.com! I have been gratified by folks responding that they WORK at these minerals. Good, that IS the idea. This way you learn about them.

The Game Plan – I will describe a mineral and you have to guess/decipher/research the name of the mineral and the answers to the other questions asked about uses, history, notable facts, etc. I expect the Top Guns in the club to be able to guess the name off the top of their heads. The learners will need a reference book or two. You will benefit most if you do not ask others for the answers but work it out for yourselves. When you have decided on the name you can compare notes with others or wait for the answers to be announced at the meetings or published in the News Nuggets. Good luck and have fun.

Last year I discussed minerals with metallic and sub-metallic lusters. This year I’ll work on minerals found in the Hansonburg District of NM. I’ll start off easy.

This month’s MM is a simple carbonate. It is commonly found in oxidized ore deposits of the metal. The rhombohedral crystals are not all that common but it also forms wonderful botyroidal groups. It has 1 perfect cleavage (3 directions) just like calcite. It is sub-transparent to translucent with a vitreous luster. It is grayish white, dark gray, green, blue, pink, or yellow with a white streak. Sp. Gr. = 4.4 to 4.5, H = 4.5.

Answers to Last Month’s MM

I’m quite surprised that more people did not answer this easy mineral!

What is the name of the mineral? Quartz (SiO2)

What is the origin of the name? From the German

quarz (uncertain derivation).

What metals does it contain? Silicon (Si, actually a semi-metal).

What non-metals does it contain? Oxygen (O)

What other minerals might occur with it? Just about everything. It would be easier to name a few that cannot occur with quartz like olivine, nepheline (and other felspathoids, etc.).

What are the names for the various colored varieties

Violet - amethyst

Yellow - citrine

Brown – smoky quartz

What other minerals might it be easily confused with? Beryl, berlinite (yeah – try looking that one up!)

What is it mined and used for? Ore of silicon, optics, glass, enamels, building materials, etc.

Do you have some in your collection? Lots!

List some famous localities

Quartz occurs all over and often in nice crystals but I’ll restrict this list a lot.

In NM – not really

In the USA – Hot Springs, AR

In the World – Switzerland, Brazil, China, etc.
