Palmer Divide Petrified Wood

Here are some of the petrified wood pieces that I picked up at my friend’s property in Northeastern Douglas County in Colorado this last weekend. The wood in Douglas County dates back up to 55 million years ago. To put this in perspective, the last phase of tectonic activity formed Rocky Mountains around 80-55 million years ago; so these are wood from the forests on the craggy, new Rocky Mountains! Interestingly, much more recently in time (about 100ish years ago), wood forested from the Palmer Divide was used to build cities like Denver. Forests have covered the land here in east-central Colorado for a long time!

So how did I find it, well, I just walked around and picked it up off of the ground, for the most part.  It tended to be all together, so once I found something on the surface, I could search around that area and find more.  I also tried digging some, and there was more under the surface as well.

Still searching for the intact logs on this property like was found recently at the Cherokee Ranch in central Douglas County!  Anyone have any suggestions for lapidary treatment of petrified wood?

What a great find!

This was one of the larger pieces I brought home.  About 16 to 18 inches long.

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!

Arkansas River Petrified Wood

Discovered some petrified wood while camping this last weekend.  We went camping in the Arkansas River valley across from Mt Antero, Princeton and Shivano.  Our secret private campsite at Ruby Mountain.  It was a muddy camp trip because of the monsoonal moisture, but that heavy rain helped cool it off in the evenings making for great camp sleeping!

I wanted to check out rocks in the Taylor Mountain / Missouri Hill area around some of the Marble and other quarries.  A fellow rockhound James was kind enough to give me some directions and advice on visiting this location, however he warned me that the road required a high clearance 4WD vehicle.  I went in our non-4WD knowing that I would probably have to park and walk a mile or two, however by the time I got up there the rains were coming in and I was running short on dry clothes.  I went almost to mile 4.5 of about 6 but eventually turned around and headed back down into the river valley.

I visit Ruby Mountain at least once per year and am not overly excited about the hard to find garnets and elusive topaz, and have more than enough apache tears from this location, so since I had a couple of hours left I decided to head down to Brown’s Canyon area as my only other visit several years back yielded nothing.  As described in Steve Voynick’s Colorado Rockhounding book, most of the side roads off of Chaffee County Road 194 past the private land lead to old Fluorspar mines.  I picked one side road and headed on a hike with my trusty Rock Hound Dog Boogie.

It was a hot day and we ended up at the mine which now is a nice makeshift gun range. It wasn’t that large of a reclaimed mine but I started to wander around and scout what was there.  I picked up many red, green, black and other cool colored stones that would I feel be great to tumble.  I found some fluorspar but nothing that great.  I was looking for smaller  fluorite crystals without any luck.  I did happen upon some agatized petrified wood and spent the rest of the hour or so I had looking for this.

Found a couple of really great camping sites while hiking as well; I hope to bring my kids back to this site someday and do some target practice, camping and more rockhounding!
