My first sketch of the rimrocks, which tower above our neighborhood, Billings, and the Yellowstone River. They provide a natural launching pad for airplanes (Billings airport is located along a portion of the rimrock plateau) and birds alike. At first glance, they seem dry, brown, and unexceptional, but if one observes them long enough, they show their sublime beauty. I find myself admiring them, especially in the early morning or late afternoon light. The rimrocks show their colors - not just brown - but oranges, reds, and yellows, plus the various greens of the trees and shrubs sparingly popping out of the rocks.
