Mount Harkness Fire Lookout, Fire lookout tower in Lassen Volcanic National Park, United States

Mount Harkness Fire Lookout was a wooden-cab observation tower built atop a stone foundation in the Lassen Volcanic National Park. The structure sat at high elevation and served as a vantage point for monitoring forest conditions across the park and surrounding valleys.

The Mount Harkness Fire Lookout was built in 1931 to a classic rustic design of the National Park Service, with a 15-by-15-foot cab on a 15-foot stone tower. It was listed on the National Register of Historic Places on 19 June 2017. The Dixie Fire destroyed it in July and August 2021.

The lookout's name comes from Mount Harkness, the peak in Lassen Volcanic National Park on which it stood at 7,985 feet. Its 15-by-15-foot cab with log catwalk and railings sat on a 15-foot stone tower, a design later recognized by its 2017 listing on the National Register of Historic Places. In 2019 it was one of fewer than 40 operating National Park Service fire lookouts, staffed and open to visitors during the summer.

The structure could be reached by hiking from Juniper Lake Campground along a forest trail that gained elevation steadily. The remote location meant visitors needed to be prepared for a demanding trek through natural terrain.
