No wildfires near Lake George, CO this fall. Controlled burns like this one can produce a lot of irritating smoke |
Nice size smoky popped out |
I got back to my dig and continued following the quartz up the hill. I was digging fairly shallow, but the sign was good and I continued to follow quartz up and into the hill. The quartz was slowly getting better with white quartz turning to grey and some crystal faces now appearing. I just pulled out my first quartz crystal and Bob appeared over the hill. I was now about 5 feet into the hill and 3 feet down. Bob sat down to watch the developing "show". Below shows the extraction of a microcline crystal.
Doesn't look like much, but a lot of work needs to be done. See picture at end for the near finished product. |
A few days later I did return to the site and mucked out the dig. A bit of snow had fallen, and the ground was frozen to about 6 inches. I carefully removed the debris I had dumped into the pocket and began extracting crystals once again. I didn't find any plates this time but did find a rather large microcline at the bottom of the pocket. I spent the entire day excavating the pocket and kept finding interesting albeit smaller crystals. A short video below details some of the action
Third trip back to the pocket. I had one area on the left side of my dig which was yielding microcline. It was over 5 feet down in the ground. There was a void, and I was able to pull out some small single microcline crystals. In order to further access this void I would have to remove about 2 square yards of rock and debris... no thanks. I'd removed the quartz seam producing the smokys that ran right through the center of the dig. Very little if any quartz was found in the void, so I decided it was time to fill in the hole.
Time to remediate the dig |
When I got home the first thing I did was rinse and then sort my finds. All microclines went in one pile and all quartz in another. Next I decided to look for fits to my plate of crystals. Immediately I recognized that some rehealing of broken crystals had taken place. Fitting rehealed crystals that had broken off the plate may be next to impossible. I refer to rehealed crystals as those that have a secondary layer of quartz over the broken areas. I then divided the crystals into small, medium, large and rehealed crystals. There was also a lot of manganese mineralization (gunk) clinging to many of the crystals and some fluoride also mucking up my finds. I also found some small, shattered fluorite crystals in some of the debris I took home to analyze.
After doing an initial cleaning I noted the microcline do have a slight bluish tint to them. Not sure the color is strong enough for the microcline to be considered amazonite. Oh well, I still have many keepers and bragging rights to an end of season hurrah! See more pictures below.
Pictured below is the large plate cleaned and reconstructed. Seven separate fits were found to the plate. The importance of taking odds and end pieces home for further analysis and possible inclusion in other pieces (plate) can provide considerable enhancement to a collected specimen.
One final cleaning and a couple of small fits will complete this plate (12.5 lbs). I found the sheared piece of microcline (right center microcline front), so that should help the look of the piece. |

My persistence digging this year was not paying off. I went from one new discovery to the next with little to show for my efforts (see this year's previous posts). I decided to return to an area where I had found goethite and amazonite in a prior year. I noticed a lot of pale but large amazonite pieces in one area and decided to give this area a second look. There was a lot of feldspar topping a large quartz blow where others had dug previously. I decided to attack the quartz and see what if anything i could find. I intently worked the boundary between the feldspar and the quartz. In order to get anywhere I had to dug and pull out some massive quartz boulders. I gave up on the idea of finding amazonite due to the overall poor color and lack of completed crystals. Most of the feldspar was encased in quartz. I was however, finding goethite. Nearly every time there was a void between the contact area between the quartz and the feldspar, I would find smoky quartz shards with goethite. It seemed the goethite had preferential growth on smoky quartz shards. Here you can see goethite wedged in between layers of quartz and feldspar in the center to the photograph. I was hoping to find some fluorite or onegite, but was unable to locate any of those specimens in my dig.

Fairly large crystals on many of these specimens |
I unearthed these discards and took many of them home for cleaning |
Here was the prize of the day and the trip, of course there were also the invaluable leaf pics. |
😮🙀😵😘😊 |
We don't see moose that often out at L George, so I was hoping for a special day. Center of picture (small and fuzzy) but I make it a practice of not stalking animals |

Another flat of goethite clinging to quartz. Only a couple smoky quartz crystals were found |
Occasionally I was rewarded with an amazonite or two though most were heavily fractured and subhedral. Slowly the seam began to pinch off and I started seeing some smoky quartz shards. The seam finally pinched off and I took some of the quartz shards home for further examination. I could some little secondary crystals on the quartz shards and hoped for some onegite. Sure enough after a bit of cleaning and further examination I determined I had found some onegite (quartz infused with goethite needles).

So ended August. Got a few things, but nothing to report to the Denver Museum of Science. Haha.
The next months post covers the Denver Show and a trip to Ouray, Colorado
Highlight of this month was some moose at Lake George, not crystals |
See below for picture of the July dig. It is hard for me to quit on float amazonite when the color is so blue.
No pocket, just single crystals |
I prospected an area a few days earlier and tried to dig there but Mother Nature kept sand blasting me with very strong winds. I ended up looking further down the hill with no positive results. I resolved to come back to this more promising spot. The next time I went out, the winds had abated, and we had a real nice day for prospecting. I found a fairly strong quartz seam and so I decided to follow the seam and see what it might produce. A couple of large dirt-covered rocks which I assumed were goethite soon popped up. Upon further inspection I found them to be fluorite. Nothing spectacular, but off to a good start. The fluorite has a clear center with a green outer layer then purple.

Next day we came out I went to the back wall of the pocket and found a lot of microcline plates and some flat plates with nearly clear quartz crystals protruding from them. Below this layer was some microcline and below that was the mud with embedded quartz crystals. As I got into the quartz layer and mud, I started seeing some humongous crystal forms.
What I thought at first was at least an 18 inch crystal.... aw shucks! |
It took me almost an hour to dig out this one crystal only to realize 3/4 of the way through the process that I most likely had a crystal that had no termination. It was becoming obvious the end of the crystal ended in the side wall of the pocket. The crystal was also attached to the pocket floor in several spots. Later I found another similar crystal but let Bob dig that one out. Sure enough, that crystal also ended with no termination. I kept looking for fluorite but found none after the first two examples the previous day. I continued digging out the bottom and back wall and only found dozens of broken quartz crystals and a few plates of microcline. I was pretty discouraged that after 2 full days of work I had not found many collectible crystals. The number of broken crystals was amazing. I went home for the day realizing I was probably done with this pocket and had a lot of remediation to do.
Next visit, I figured I better check everything over one more time before I filled my 5-foot hole. Once I fill this in there will be no going back to redo it. I definitely don't want any diggers remorse thinking, what if I had dug here or a little over there... I double checked everything. I pulled out country rocks from the pocket floor, checked the sides and even backed up a bit. I found a few 2-inch quartz crystals but nothing I would have regretted leaving. Toward the end of the day, I found one fairly large microcline crystal and put that in my shirt pocket. I left most of the microcline plates at the dig site. While the plates of microcline were large, the microclines were fairly small and spotted with iron material... yard rocks at best. I spent about 2 hours remediating the dig and probably have a little bit more to do. The weather began to turn south, and lightning started to crackle nearby. On the drive home Bob commented on the fact I seem to have a knack for finding microcline twins. I had only found one baveno twin, not much considering all the microcline I dug out. It was then that I reached into my shirt pocket to take a look at the silver dollar size microcline I found earlier. It was the last crystal I took from the dig. I wiped a bit of mud off it and sure enough it was a Mannebach twin.

Many years earlier I found a pocket that I called the Waste of Time pocket. This was a close second to that find. Still, digging for hours and sifting through material is fun. You never know what might turn up. All in all, I still enjoyed a very nice time in the forest.
When I got home, there is the sorting and cleaning process. A couple small surprises included fluorite attached to some of the smoky quartz crystals. Noticed a few microcline plates that included smokeys. After looking at the crystals it seemed the crystal pocket went through various crystal building events.

The pocket was first formed with crystals that were irradiated and became smoky. Something in the pocket then etched many of the smokys. Next was a secondary infusion of quartz which coated many of the first-generation etched crystals with a clearer layer of quartz. This event created hooded or phantom quartz crystals. Next up was some fluorine in solution. There are chunks of fluorite as pictured above. Some of the clearer second-generation quartz crystals have small fluorites attached to them as well. At some point some albite and iron oxides also came into the pocket to add some variety. Of course, this is only a hypothesis, and I am sure some will disagree with my conclusions.
I may post more pictures of the specimens collected at a later day. Now I'm off in search of another pocket of crystals :-)
On Peterson Mountain, NV, near Hallelujah Junction (all good pics courtesy of Austin) |
I've been wanting to do some digging on Peterson Mountain for 10 years. Despite the fee, I got an offer I couldn't refuse. Austin Cockell invited me to come with him and do some digging at one of the pay-to-dig claims. We visited the Royal Scepter mine and both thoroughly enjoyed the trip. Austin had been to the site the previous year and so we had no trouble finding our way up the mountain. We camped near the top and enjoyed some panoramic views. The mountain is notorious for its well known winds and Mt Peterson didn't disappoint. Fortunately the winds died down the first night and we were able to get some shut-eye. Since all of our digging was in a pit, the winds were only moderately inconvenient as they blew over the top of us. You may see some pebbles flying across your field of view in some of the videos. The main collecting mineral for this site is quartz. The number of separate molten silica infusions into the mountain cracks provides a multitude of various types/habits of quartz. The main draw to Peterson Mountain are the fabulous sceptered quartz crystals.
The stewards of the mine supplied us with the essentials to find crystals. The whole process was made exceptionally easy with track hoes scrapping the pit and front-end loaders hauling away the debris. An electric vibrating chisel was also very handy for breaking down the edges of pockets. Wrapping paper boxes and other tools were also provided to carefully secure/protect our finds and transport them to our vehicles at the end of the day. The miners used the heavy equipment to break down rock in the claim area into three different steps or benches. Both sides and bottoms of the dig area were well scrapped so we could see quartz outcrops and follow the seams to crystal pockets. I explored 4 pockets with minor successes and then I hit a nicer pocket in the wall of the lowest level of the claim

I probably harvested at least 100 crystals from this beach ball sized pocket. Many of the crystals were broken, but fortunately there was a secondary infusion of silica into the pocket. This secondary infusion of quartz formed some candlesticks and scepters on the terminations of some of the broken smoky quartz crystals and provided spectacular rehealed crystals. I noticed that much of the broken material was very gemmy, but I had to pick and choose a bit what specimens were going to travel back with me on the plane.
Next was Austin's turn to make a crystal score, and he came through in a rather big way (pun intended). for those of you who don't know Austin, he is about 6ft 10. Soon a crowd gathered around his digging spot as he pulled out one 6 inch crystal after the next. After a couple hours I wandered over to see what Austin was up to. Once again, he was pulling out wonderful quartz crystals. I decided he was getting better crystals than me because of his height advantage. haha.

After about 6 hours of digging solo, we decided to dig together a bit. I barely sat down next to Austin when he pulled out the best scepter of the day. Definitely a most royal scepter. Shortly after his find I also found a nice scepter, though Austins scepter has a much longer stem. See pictures below.

I consider these to be magnificent scepters. The one to the right is truly exceptional!
An excellent bi-monthly magazine put out by the Mineralogical Record just came out. If you wish to do more in depth reading on mining at Peterson Mountain, I suggest you buy the 2022 Mar/Apr edition.
