The peak, though not the first lookout built on the San Bernardino National Forest, it is the oldest "original" tower. It is located three miles east of Running Springs at elevation 7882 ft (2317 m). The Keller Peak topographical map shows the lookout at 34-11-45 N and 117-02-56 W. The peak is reached from the Keller Peak road from Highway 18, 1.5 miles east of Running Springs. It has a fire lookout, cliffs and a meadow adjacent. The National Children's Forest is located on the road from the highway to the peak.
All of the places are named for Ally Carlin Keller, born in San Bernardino in 1868, who at one time was an employee of the Forest Service. His father, Carlin Keller, was an early pioneer in the area. This picture shows the Osborne Fire Finder that is still in use. (click for larger image) You can view two memorial plaques at Keller Peak lookout. The first designates the 1926-built tower as an historic landmark. The second, located 200 yards (175 m) to the west, marks the spot where a B-26 bomber crashed December 30, 1941. Some of the wreckage is still visible.
