North Centre’s center stands about 960 ft above sea level. Within three miles the land runs from 570 ft to 1,650 ft, a difference of 1,080 ft: steep hill country. The highest named summit within 15 miles is Catawissa Mountain, about 1,960 ft, 14 miles south-southeast.
Under the town center the state geologic map shows Sherman Creek Member of Catskill Formation (siltstone, mudstone), from the Late Devonian, 359 to 384 million years old.
The section below crosses 10 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 15×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Siltstone, shale. Age: Late Devonian, 359 to 384 million years old. About 8 mi of the line.
Black-shale. Age: Early Devonian to Middle Devonian, 384 to 422 million years old. About 4 mi of the line.
Siltstone, mudstone. Age: Late Devonian, 359 to 384 million years old. About 3 mi of the line.
Shale, siltstone, sandstone. Age: Carboniferous, 324 to 359 million years old. About 3 mi of the line.
Siltstone. Age: Late Devonian, 359 to 384 million years old. About 2 mi of the line.
Shale. Age: Silurian, 422 to 445 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 4 smaller units along the line are not listed.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in North Centre reaches Chesapeake Bay and the Atlantic Ocean by way of West Branch Briar Creek, Briar Creek and the Susquehanna: about 170 river miles.
Lake on the way: Lake Aldred.
120 miles of the trip are on the Susquehanna.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of North Centre; river miles along the main stem, rounded.
