Watch Your Step18x24, oil on linen, Available. Combining plein air and photo reference is a great joy to me. Having painted in many western towns, as well as in the Eastern Sierras, I have lots of good plein air resources and images available. In this painting, the colors and terrain itself were gathered on location in the southwest. The image of the man on the mule is from my painting pack trip to Sailor Lake, an area above the Sabrina basin at approximately 11,000 feet elevation.
