Jersey Hill, a 2,251-foot mountain in Allegany County in New York’s Southern Tier, is historically significant for its role in forest-fire detection. In the 1930s, the Civilian Conservation Corps improved the area for fire control, building tower footers in 1934 and erecting a 79-foot-6-inch steel International Derrick lookout tower in 1935. The effort also included nearby truck trails, fire breaks, and water holes to support firefighting and protect state forest land. Unlike more interconnected fire tower systems elsewhere in New York, Jersey Hill’s tower was staffed only as needed. Its role declined with aerial fire detection, and the tower was removed in August 1987.
