The Laceyville 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.
Laceyville’s center stands about 720 ft above sea level. Within three miles the land runs from 630 ft to 1,300 ft, a difference of 670 ft: hilly country. The highest named summit within 15 miles is Bartlett Mountain, about 2,410 ft, 9 miles south.
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 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 11×. 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 23 mi of the line.
Sandstone, siltstone. Age: Devonian to Carboniferous, 324 to 422 million years old. About 1 mi of the line.

A raindrop that lands in Laceyville reaches Chesapeake Bay and the Atlantic Ocean by way of Little Tuscarora Creek and the Susquehanna: about 250 river miles.
Lake on the way: Lake Aldred.
200 miles of the trip are on the Susquehanna.
