Comb Ridge, the Comb Wash, and the Abajo Mountains, in southeastern Utah
Comb Ridge, in southeast Utah, snakes across the center of the photo. It marks the edge of the Monument Upwarp, in which the area in the camera location was thrust upward and eastward in a continental collision 70 to 40 million years ago. Subsequent erosion of the resulting dome has exposed the Triassic and Jurassic layers, deposited hundreds of millions of years ago, that we see between here and Comb Ridge. In the background are the Abajo Mountains, laccoliths (lava that formed underground) that formed 30 to 20 million years ago, after which the layers of rock covering them eroded away.
