The Herrick 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.
Herrick’s center stands about 1,210 ft above sea level. Within three miles the land runs from 940 ft to 1,490 ft, a difference of 550 ft: hilly country. The highest named summit within 15 miles is Robwood Mountain, about 2,350 ft, 13 miles southwest.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 12×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone, siltstone, shale. Age: Late Devonian, 359 to 384 million years old. About 13 mi of the line.
Sandstone, siltstone, mudstone. Age: Late Devonian, 359 to 384 million years old. About 10 mi of the line.
Sandstone, siltstone. Age: Devonian to Carboniferous, 324 to 422 million years old. About 0.8 mi of the line.
Sandstone. Age: Carboniferous, 324 to 359 million years old. About 0.3 mi of the line.

A raindrop that lands in Herrick reaches Chesapeake Bay and the Atlantic Ocean by way of Cold Creek, Wyalusing Creek and the Susquehanna: about 270 river miles.
Lake on the way: Lake Aldred.
210 miles of the trip are on the Susquehanna.
