Walls and terraces and man made features help define a landscape. In some cases, as in the foothills of the Sierras the lines of definition comes from an animal source. The textured contours of all the hills that I’ve tried to paint here are created by the constant grazing of cattle along parallel lines in narrow terraced elevations around the sides of all the slopes. I find it fascinating. As if the hills are made of many layers of stacked pieces of corrugated cardboard.
