The Munnsville 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.
Munnsville’s center stands about 680 ft above sea level. Within three miles the land runs from 580 ft to 1,650 ft, a difference of 1,070 ft: steep hill country. The highest named summit within 15 miles is Mount Hunger, about 1,970 ft, 14 miles east-southeast.
The section below crosses 9 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 14×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Black-shale. Age: Middle Devonian, 388 to 394 million years old. About 8 mi of the line.
Shale. Age: Silurian, 422 to 428 million years old. About 4 mi of the line.
Limestone. Age: Early Devonian, 394 to 422 million years old. About 3 mi of the line.
Shale, limestone, dolostone. Age: Silurian, 422 to 428 million years old. About 2 mi of the line.
Shale, siltstone, sandstone. Age: Middle Devonian, 384 to 394 million years old. About 2 mi of the line.
Limestone. Age: Early Devonian to Middle Devonian, 388 to 410 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 3 smaller units along the line are not listed.

A raindrop that lands in Munnsville reaches Lake Ontario by way of Oneida Creek, the Oneida and the Oswego: about 90 river miles. From the lake it goes down the St. Lawrence to the Atlantic.
Lake on the way: Oneida Lake.
