Ship Rock is the erosional remnant of the throat of a volcano. It was originally formed 3000 feet below the earth's surface and exposed after millions of years of erosion. Huge dikes radiate from the central formation in the distance. A landmark in Northwestern New Mexico and Northeastern Arizona, this huge rock is visible from as far as fifty miles away. The rock itself, which resembles a sailing ship when seen from one side, appears as a rough triangle here. I was drawn to this scene because of the triangular shapes at either side of the cattle crossing, framing the entrance to the road. The ridge that leads to Ship Rock also offers several implied triangles. Triangular shapes repeat throughout this image, linking the foreground to both the middleground and background.
