2023 Map of Otisco Valley

About this map

Otisco Lake and the steep ridges of the Finger Lakes region define this landscape at the border of Onondaga and Cortland counties. The area is characterized by high-elevation hills like Dutch Hill and Preble Hill, which are deeply incised by narrow gorges such as Rattlesnake Gulf and Emerson Gulf. This 2023 survey documents a predominantly rural and residential character, where long-established hamlets like Vesper and Bromley are connected by a network of county roads. Genealogists will find a high density of burial grounds throughout the townships, including Saint Patricks Cem and the Cold Brook Valley Cem. Further east, the terrain descends into the Tully Valley, where the glacial kettle lakes Song Lake and Crooked Lake serve as centers for communities like Tully Lake Park and Assembly Park.
