About this map

Penn Yan serves as the focal point of this Yates County landscape, situated at the north end of Keuka Lake where the Lake Outlet begins its eastern descent. The early twentieth-century economy is clearly visible through the string of industrial sites following the water downstream, including Milo Mills, Seneca Mills, and Keuka Mills. These milling operations, powered by the lake's drainage, underscore the region's reliance on water for early industrial processing.

Transportation patterns of the era are particularly well-defined, showing the Northern Central R. R. cutting through the northern townships while a designated Steamboat Route traverses the West Branch and main body of the lake. Settlements like Branchport, Keuka Park, and Guyanoga are connected by a network of rural roads that climb the steep slopes of the Bluff Point peninsula. This survey, conducted by Albert Pike and colleagues, documents the transition from water-borne commerce to rail and early electric lines.
