Initially used as a patrol point in the 1920`s, the first tower built was a 35` pole L-4. In 1973, an 8x8` cab was installed atop the radar installation, with no living quarters. The present 45` all-steel live-in tower was constructed in 1983 and is staffed every summer. Photo courtesy of Gary Weber.
