New Schaefferstown’s center stands about 480 ft above sea level. Within three miles the land runs from 330 ft to 680 ft, a difference of 350 ft: rolling country. The highest named summit within 15 miles is Eagle Peak, about 1,320 ft, 8 miles south.
Under the town center the state geologic map shows Shale and graywacke of Hamburg sequence, from the Ordovician, 445 to 487 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 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.
Shale. Age: Ordovician, 445 to 487 million years old. About 9 mi of the line.

A raindrop that lands in New Schaefferstown reaches Delaware Bay and the Atlantic Ocean by way of Little Northkill Creek, Tulpehocken Creek, the Schuylkill and the Delaware: about 150 river miles.
75 miles of the trip are on the Schuylkill.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of New Schaefferstown; river miles along the main stem, rounded.
