Some great geology views while traveling including this great view of the Keystone Thrust Fault.
There are plenty of thrust faults in Washington State, but not nearly so well exposed and easily seen. Amongst geologist this thrust fault is a famous location. Something to look for when you head into or out of Las Vegas, Nevada.
In my case I was just flying over the area. And, no, I was not on a get-a-way-from-winter trip. We had all of 1/2 hour in Phoenix between colder locations.
One other note as the great Southwest Drought has been in the news. Mount Charleston approximately 25 miles west northwest of Las Vegas had a very thin dusting of snow. Not good given that it was early February, and it took me a bit to convince myself I was indeed looking at Charleston. I have been on the 12,000-foot ridge of Charleston in late May and seen more snow.
