The LeRaysville 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.
LeRaysville’s center stands about 1,460 ft above sea level. Within three miles the land runs from 1,050 ft to 1,660 ft, a difference of 610 ft: hilly country. The highest named summit within 15 miles is Cork Hill, about 1,940 ft, 12 miles north-northeast.
Under the town center the state geologic map shows Catskill Formation (sandstone, siltstone, 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 17×. 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 12 mi of the line.
Sandstone, siltstone, mudstone. Age: Late Devonian, 359 to 384 million years old. About 11 mi of the line.
Sandstone, siltstone, shale. Age: Late Devonian, 359 to 384 million years old. About 2 mi of the line.

A raindrop that lands in LeRaysville reaches Chesapeake Bay and the Atlantic Ocean by way of Ford Street Creek, Ross Creek, Wyalusing Creek and the Susquehanna: about 280 river miles.
Lake on the way: Lake Aldred.
210 miles of the trip are on the Susquehanna.
