Esther Mountain is a mountain located in Essex County, New York. The mountain is the northernmost of the High Peaks of the Adirondack Mountains and its 28th highest peak. It was the only High Peak named for a woman until 2014, having been named in honor of Esther McComb, who made the first recorded climb to the summit in 1839, at age 15; at the time she was attempting to climb Whiteface Mountain from the north (Whiteface is a higher mountain which flanks Esther to the south).
