The first people to witness this view were probably Indians who had to scale the steep cliffs and talus slopes. Later, ranchers dug narrow passages up into the canyons to bring their cattle to graze in the rich highland trails below. Begun during the Great Depression and completed after World War II, scenic Rim Rock Drive remains an eloquent tribute to those who build it. Skilled workers, many from the local area, did the challenging work of drilling, blasting, and masonry while manual labor was done by hard working young men of the Civilian Conservation Corps.
