Catskill Mountain fire towers

The Catskill Mountain fire towers were constructed to facilitate forest fire prevention and control in the Catskill Mountains of New York. 23 towers were built between 1908 and 1950. The towers fell into disuse by the 1970s as fire spotting from airplanes became more effective, and were gradually decommissioned. The Hunter Mountain Fire Tower was the last to be taken out of service in 1990. Most of the towers have been dismantled, but the five remaining towers have been renovated and opened to the public for observation: the aforementioned Hunter Mountain tower, the Balsam Lake Mountain Fire Observation Station, Overlook Mountain Tower in Woodstock, Tremper Mountain Fire Tower in the town of Shandaken and Red Hill Fire Tower in the town of Denning.
