This is a pastel, 7"X10", done on Wallis sanded pastel paper. (It's archival paper --- my question is -- is it archival sand?) I was on my 1,300 mile trip home from the workshop I attended in Cody, WY when I had to stop the car and take in this beautiful sky and color over the mountains. This is my second attempt at this. I did one that did not really capture what I wanted, so I bit the bullet and did another and like this one better. No, I am not going to post the other one.
