Tumamoc Hill is one of my favorite places to paint. It is a Sonoran Desert preserve, historical landmark, and archeological preserve surrounded by urban Tucson. I've been going up to Tumamoc Hill regularly to make quick on-location paint sketches. In these sketches I am paying close attention to getting the subtle colors of the "desert palette" which I can only get from on-location painting. Even the best reference photos distort the true colors of the desert. This is a studio painting using my on location sketch as reference.
