July 28, 1938: "Carrying steel on mule back, for 15 miles, from Ojai Valley up a winding trail to the 6,000-foot summit of Topa Topa peak, for a 20-foot steel lookout tower, was commenced last week-end by Sherman Mansfield, chief U.S. forest service packer, who is using the government mule train from Los Prietos on Santa Ynez river canyon, for the big job. Window glass, lumber and all other materials for the tall tower will be delivered on the sky-soaring peak, after which Peter Nielson, U.S. forest construction superintendent, of Santa Barbara, and his crew, will ride astride government mounts to the peak to spend several weeks in erecting the tower. From the lookout a wide survey of the Sespe country will be possible, looking down into canyons that heretofore had been out of sight of other lookouts." (Piru News)
September 16, 2006: The wood cab was burned off the steel 'H' brace tower in the Day Fire that threatened several other lookouts.
