In 1928 the Los Angeles County Forestry Department constructed a fire lookout in the western high point of Blue Ridge. As with most county towers, the Blue Ridge lookout station was built with a nearby stone cabin for the lookout staff. It stood only for 2 years as the forest service decided it would be best to move it to a location in the Santa Monica Mountains (to Bodel Peak). So the structure and history were only here briefly. Today, the site is a location for private towers and the Frost benchmark at 8484 feet. There are concrete footings at site but its not certain whether they belong to the tower or the cabin.
