Black Mountain, in Washington County, New York, stands apart from the Adirondacks across Lake George and is both the county’s highest point and the tallest peak encircling the lake. Its isolation gives it one of New York’s greatest topographic prominences, and its ancient Precambrian rocks place it among North America’s oldest mountain regions. The summit includes a weather station, wind turbine, and a steel fire tower that replaced an earlier wooden lookout in 1918 and served observers until 1988. The mountain also preserves a disputed naming tradition, an authenticated “R. Rogers 1763” inscription, and a place in Lake George’s artistic and recreational history.
