August 19, 1969: "The Forest Service's Warm Springs lookout tower first spotted smoke rising near the reservoir used by the Los Angeles Dept. of Water and Power to store water from the Owens River of central California. Smoke and heat from 25-foot flames three times in the late afternoon triggered the automatic shutdown of a power transmission line that supplies electricity for most of the heavily-populated San Fernando Valley."

September 1987: A fire northeast of Castaic Lake made a run up Elizabeth Lake Canyon consuming many acres and in the process burning the lookout.
