Blue Mountain was written by Judge Fred Keller about the cowboys around the town of Monticello, Utah, near the Blue Mountain, an isolated range at the divide between the
Colorado and San Juan Rivers in Utah. On an otherwise naked slope of the Blue Mountain, spruce trees grow in the outline of a horse’s head. This feature is very distinct in the winter, when you
can see the head of a blazed-faced horse looking over the mesa. From earliest times the cowboys have considered the horse head a scenic wonder.
