The trip out to Denver can be done several ways.  My favorite is to blast across northern California north of Mt. Lassen and then go through Reno and head toward Fallon on I-80.  From there it is US Hwy 50 across Nevada and Utah and then to I-70 which takes you all the way through to Denver.  It is 1250 miles or so and takes me 2 days to do it. Well this year it was all I-80 from Reno to Laramie, Wyoming.  The first leg is to drive north of Mt. Lassen and then hook up with US 395 at Susanville and take that all the way to Reno.  One of the things I failed to consider is what the availability of all that "Stimulus" money might have on road departments.  Much of I-80 across Nevada was one lane.... %!)_)#&&@ 

 

Now the road log...

Speeding on US 395 toward Reno.

 

Battle Mountain, Nevada has not got much going for it so I guess this will have to do.

 

Just east of Carlin, Nevada is the Univ. of Nevada's fire school.  It was oil fires on this day.

The Utah/Nevada border at Wendover situated near the Bonneville Salt Flats.

 

About 20 miles from Salt Lake City you can see some old wave benches cut when Lake Bonneville was MUCH deeper.

 

About 2 miles east of the Utah/Wyoming border is one of the places every 13 year old male in America dreams of...

 

Wyoming is also noted for its expansive coal mines.

 

Most of Wyoming along I-80 is beyond boring.  After a while all you can do to stay awake is count antelope which are incredibly abundant. I stopped counting after 350...

 

Ok enough on the Travel Log.  Time for rocks!

Before leaving for Denver I put together a few updates for this show.  The first is a new "old" find of axinite-mg.  This past spring I was contacted by a fellow, now living in Seattle, Washington, who had lived in the Butte County area when California Highway 70 was being built back in the 1960s. During this time numerous outcrops with ferroaxinite were encountered.  However, one small podiform deposit caught his eye.  In one small deposit there were numerous, bright lustrous, pale beige to plum colored crystals of axinit associated with albite. At the time of the call, as it turned out, there was a show in Seattle that Marcus Origleri was attending.  I asked Marcus if he could swing by and take a look.  He graciously agreed and suggested that I get up and get these as they were clearly not "normal" axinite from California.  I had specimens analyzed by Bart Cannon for their repsective iron and magnesium compositions (In the world of minerals there are rarely nice homogenous things to anlayze.  In most cases where axinite is formed there will be a solid solution series of elements such as manganese, iron and magnesium. At some point the amount of one element or the other determines what we call them). These axinite specimens fell out at slightly more than 4% MgO.  The true end member of Axinite-Mg is 7.48% MgO.  After conferring with Marcus he pointed out that the determining point for classificiation as Axinite-Mg is 3.6%.  So, by that definition these can be legitimately called "iron rich" Axinite-Mg.

These crystals have a color change property going from light beige/colorless in sunlight to a light plum color under incandescent lighting.They are also very weakly fluorescent red under SW UV light.

Another lot of interest are some prismatic calcite crystals from Dachang Mine, Nandan, Guangxi, China.  At first clance they look like quartz crystals. The internal cleavage planes quickly dispell that though.  I don't usually get ramped up over calcite but these caught my eye with their strong luster and sharp crystallization.

I also found a small group of jouravskite specimens recently. Jouravskite is one of the rarest species from the N'Cwaning mine.  It is closely related to Sturmanite, sttringite and Charlesite.  The presence of manganese is the distinction.  Jouravskite always is found in compact aggregates of small crystals.  It just doesn't get any better than that.

I have also included several random things from various locales in the first update.

There will be a lot more to come in the next week so stay tuned for new finds from here in Denver, Colorado!
