The Hector plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
Hector’s center stands about 850 ft above sea level. Within three miles the land runs from 440 ft to 1,550 ft, a difference of 1,110 ft: steep hill country. The highest named summit within 15 miles is Connecticut Hill, about 2,140 ft, 13 miles southeast.
Under the town center the state geologic map shows Genesee Group (shale), from the Late Devonian, 359 to 384 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 13×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale. Age: Late Devonian, 359 to 384 million years old. About 10 mi of the line.
Shale, siltstone. Age: Late Devonian, 359 to 384 million years old. About 7 mi of the line.
Shale. Age: Late Devonian, 359 to 384 million years old. About 5 mi of the line.

A raindrop that lands in Hector reaches Lake Ontario by way of Hector Falls Creek, the Seneca and the Oswego: about 130 river miles. From the lake it goes down the St. Lawrence to the Atlantic.
Lakes on the way: Seneca Lake and Cayuga Lake.
