Trees and Colorado Mountains (Drawing from Sketchbook)

Trees and Colorado Mountains (Drawing from Sketchbook), a photo by randubnick on Flickr.

This is a drawing that I found in an old sketchbook of mine. There's no date, but this looks like drawing from observation. I think this is from a trip to Colorado, maybe to Snowmass or Breckenridge, sometime in the 1980s. I think this is done with craypas (oil pastel) or maybe a combination of crayon and conte crayon. Anyway, I like the composition and the color. I don't think I finished it. (It doesn't look finished to me now.) Anyway, I am thinking about working on it some more. . . .
