The summit area, leveled off for the gap-filler radar facility, shows up well from this angle.

Fire Lookout
Slate Peak. This was to be a location of an early warning radar site in the 1960`s. The top of the peak was leveled off to accommodate the radar site, but then the site was never built. All that remains is a large concrete slab. The peak has a US Forest Service fire lookout.
