Painted Hills Glow
The color-splashed knobs, hummocks and hills of bentonite are the eroded remnants of the John Day Formation. The weathering of volcanic ash under varying climatic phenomena resulted in vividly-hued layers of red, pink, bronze, tan and black. The colors are intensified when the landscape is wet and the light is soft. The Painted Hills literally glow. Photo © copyright by Robert Faucher.
