Milesburg’s center stands about 700 ft above sea level. Within three miles the land runs from 670 ft to 1,680 ft, a difference of 1,010 ft: steep hill country. The highest named summit within 15 miles is Thickhead Mountain, about 2,420 ft, 15 miles south-southeast.
The section below crosses 20 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, shale. Age: Devonian to Carboniferous, 324 to 422 million years old. About 3 mi of the line.
Dolostone. Age: Cambrian, 487 to 542 million years old. About 2 mi of the line.
Sandstone, siltstone, shale. Age: Late Devonian, 359 to 384 million years old. About 2 mi of the line.
Sandstone, siltstone, mudstone. Age: Late Devonian, 359 to 384 million years old. About 2 mi of the line.
Dolostone. Age: Ordovician, 445 to 487 million years old. About 2 mi of the line.
Sandstone. Age: Carboniferous, 324 to 359 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 14 smaller units along the line are not listed.

A raindrop that lands in Milesburg reaches Chesapeake Bay and the Atlantic Ocean by way of Bald Eagle Creek, the West Branch Susquehanna and the Susquehanna: about 230 river miles.
Lake on the way: Lake Aldred.
85 miles of the trip are on the Susquehanna.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Milesburg; river miles along the main stem, rounded.
Milesburg has a hot-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 21° in January. A normal year brings about 44 inches of snow; with the rain, that comes to about 42 inches of water.
On November 14 Milesburg normally reaches 49° and falls to 34°. The record high is 70°, in 1902; the record low 13°, in 1986. The most rain on this date, 0.66 in, fell in 1972.
Normals 1991–2020 and records since 1882 at State College, 11 miles south-southwest, 470 ft higher. NOAA, through RCC-ACIS.
