2015 Denver Gem and Mineral Shows

Was able to break away from our busy schedule and make a trip to Denver for a couple of the Denver Mineral Shows. As always we head to the Merchandise Mart for Zinn’s show as this is where all the display cases are. I have included many photos from these cases as there were some outstanding specimens on display this year. We also went to the Colosseum Show. I find that I don’t buy too many minerals, especially ones that I can find locally here in Colorado. Instead, I tend to focus spending my money on literature, display mounts and tools. I bought a subscription to the Mineralogical Record and man these are amazing journals! I suspect, although pricey, I’ll be a subscriber for a while. In the January/February 2015 issue on the fantastic Pederneira Mine in Brazil I learned much about pegmatites, some information relevant to where I dig!

Here are some of the cool minerals displayed in the specimen cabinets at the main show. Obviously a small selection as there were tons (literally) of beautiful and amazing minerals on display, just some that caught my eye. Many are Colorado or close-to Colorado specimens, a bit of scouting as I may pay a visit to those localities in the upcoming years!

Prospecting Topaz near Pilot Peak

I was invited to prospect Topaz with an experience prospector, James, on his Topaz Claim near Pilot Peak about half way between Tarryall and Lake George, Colorado. Pilot Peak is likely one of the best Topaz localities in Colorado!  I have found topaz in this area before and was excited to learn more about prospecting topaz in the hopes that I can utilize this information to find that elusive stone in my favorite collecting areas around Devil’s Head.

Looking towards Pilot Peak, this area is jammed pack of claims. The only one (periodically) open to the public is the Topaz Mountain Gem mine.

Here are some links to prior topaz days around this area:

We started the day finding the claim’s corner points (and posts, which are required on all active mining claims) and James showed me some areas of interest that he had in his earlier prospecting trips.  The first spot we happened upon was where there were nice signs of pegmatite on the surface, some rocks had quartz with flat sides which is always a great sign!  We dug here for a little while but couldn’t find anything interesting in the area. We dug uphill a little ways but still nothing similar to what we found on the ground. Perhaps this was a little seam left over from long ago  that was then above the surface level and has been sitting on top of the ground since?  Perhaps we just missed the small area?  Regardless, nothing was found in this area although I definitely feel that the area is worth more consideration and putting down test holes.

Float that was worth checking out.

In another spot we found a seam of finer grained granite (aplite) with some pegmatite. Following the aplite seam around we found a couple of spots that opened up; one into a small pocket (that someone before us had cleaned out).  Although we didn’t find anything worth keeping, it was great to see these signs.  I also experienced that pounding with chisel into granite is a lot of hard work!

Here was the small pocket (with iron/red dirt). This vein flowed for about 100 feet.

Pegmatite lined this solid granite boulder, once part of the massive granite outcrop. White quartz with no signs of crystals.

We did quite a bit of hiking around the 20-acre claim area, which includes steep terrain filled with bushes and aspen trees, boulders big and small are everywhere.  There was a lot of up and down traversing the claim and by the end of the day we were exhausted, good news is it was awesome exercise!  The greatest part of climbing these hills was the magnificent views–part of the fun when prospecting the Colorado Rocky Mountains!

Again thanks to James for all the information and fun day on his claim!  I learned quite a bit about topaz prospecting!

Rockhounding Wigwam, Jefferson County Colorado

June 8, 2014.  I had the opportunity to visit a private claim with the Lake George Gem and Mineral Club in this famous Colorado locality in spring 2014.  The area and drive to the locality is beautiful; a stretch through the Hayman Fire burn area which occurred on this same date twelve years prior in 2002.

Wigwam area is in the heart of the Hayman Fire burn area.  This is 12 years later (to the day).

The area is typical pegmatite digging; although it is several feet deep.  I ended up digging a few test holes but found no peg and only found float type material that didn’t pan out.  I started checking out natural washed tailings from previous digs and noted there was some amazonite in a certain area, so I started to dig in that general area.  After a while I started seeing stepped/parallel growth on top of quartz chunks mostly anhedral with some faces.  I tuned into where these were running finding a general seam and out popped some amazonite and quartz crystals that were really cool, in the soil no more than 8″ deep.  That seam pinched out but I came home with some really unique crystals.

The first crystal I found in this spot which prompted me to spend 5 more hours in this area!

My second visit was to see if I missed this seam going in any other direction.  After digging many hours I didn’t find any further remnants of the seam but in the general area there were many types of crystals–some partial amazonite crystals, some more quartz chunks with parallel type growth which in some cases grew bigger as the seam opened up slightly, and more clear quartz growths on other crystals or host rock.  I even found a fluorite crystal!  I pulled out very few euhedral crystals but there were some amazonite and milky quartz.

I call it “The Right Foot” (due to it being found in the rightmost foot of my dig, among other obvious reasons), awesome unique quartz crystal!

It was fun to meet other members of the club and to visit this locality I’ve been meaning to pay a visit for years!

May 2013: Goethite and Onegite

May was a fun month for rock hounding adventures.  I visited the Lake George area several times in May, the first was to prospect and find the claim borders / corner posts, I went with my son and his friend.  We had a fun hike and I found a couple of spots that looked interesting.  I then came back and the first rock I turned over had a small spray of Goethite on it.  I have never found Goethite before and so I was pretty excited.  Ended up digging at this location for two days and pulled out a lot of Goethite and related Onegite sprays, some combo pieces, and many Smokey Quartz crystals and small microcline clusters.  No amazonite, however, but that is okay as I had a wonderful time with what I did find.

Looking at these sprays under a loupe I discovered that there are small citrine, smoky and amethyst quartz crystals all over these things.  I guess that is by definition the Onegite — Goethite with these small crystals.  I read online on how to clean these and have soaked them in soapy water for days and then used water spray to avoid breaking the delicate crystals.  On some of the onegite I was able to use a soft toothbrush.  They didn’t clean up 100% yet; I don’t know if some ever will.  Note you can’t put them in Iron Out since this is an iron based mineral.

I will post some of the microcline and smoky quartz in a different post when I have them ready; but here is a slideshow of some of the pieces that I found.  What a cool mineral!

2012 Colorado Topaz

This year was a great year for topaz; my family and I had a couple of wonderful days with the Dorris family at the Topaz Mountain Gem mine.  See previous posts (1, 2) for details on these trips.  On May 5th I found a really nice (300 carat!) beautiful blue specimen topaz that Joe suggested I have his son professionally clean and seal some of the fractures using pressure treatment.  I went ahead and took advantage of this and the crystal came back just beautiful.  I’m not sure how many fractures were actually sealed as it is still fractured up; but the color is wonderful and crystal clean (probably where the term is derived?)!

Cleaned 300 carat blue topaz crystal cleaned, pressure treated and ready for the cabinent!

I am very happy with the results, well worth the investment!

I am also very pleased with the cut topaz that came back from Joe’s cutter in China.  These take a while to process, but well worth the wait.  This year was about 4 months quicker than last year as well; so I was pleasantly surprised to see these just after the new year!

I found a really nice sherry stone and had it cut.  Joe thought that for sure one nice stone could be cut; but potentially 2.  Was surprised to see three stones were cut from this!  Here is the original stone:

And here are the cut stones it produced:

Bi-color sherry stone.  Simply beautiful!

 

The right stone was the surprise; it had some inclusions which are really beautiful.  The left gem was from another clear stone I found in July; these will make a nice pair on some piece !!

The right stone with hematite or iron oxide inclusions is from the Sherry Stone

Back side!

And another smaller stone was cut from the large stone.  Here are a couple of other stones I received, a total of 30 carats for 2012!

Beautiful gem from 2012!

My daughter is in love with these stones and is now re-energized to spend the day digging for stones soon!  Hopefully we’ll have the opportunity to go back several times again in 2013!  And I hope I finally dig an elusive stone at Devils head this upcoming year!

CSMS Field Trip: Joe Dorris’ Topaz Mine 2010

Topaz Gem Mine 2010
My dad and I were fortunate to go on the annual field trip with the Colorado Springs Mineralogical Society to Joe Dorris’s Topaz Mine. This was a great day and Joe was a wonderful host! The day started by us just sifting through some piles of dirt with rakes. Joe and his son were using the excavator and had us move a couple of times to ensure we were out of harms way.
Dave Sifting through the dirt
My dad constructed a nice screen and we used this all day long. I found that I didn’t need the screen though, when you find a topaz it is very shiny and stands out as the dirt does not stick to it. We found several small stones in blue and yellow color. Joe also provides “bags of dirt” that we purchase to help offset the costs of having us as visitors all day and he “spikes” these bags with a few stones. There was a nice and huge ~150 carat tumbled alluvial stone in my bag!
Excavator at work
Here is a beautiful stone that Joe found at the end of the day after almost everyone left (my dad and I stayed until Joe’s team left). When the excavator unearthed this beauty, we all saw it at once; they are pretty easy to see when they are this big!
Beautiful Topaz Joe's team found
After all was said and done; my dad and I had a wonderful day and between what we found and the gifts planted in our “bags of dirt” we feel we really scored! Huge thanks goes out to Joe Dorris for hosting and the CSMS club for arranging this wonderful day!
