9° on Nov. 16, 1933, the coldest reading for this week of the year since 1882. Next is 12° in 1883.
Hawk Run’s center stands about 1,460 ft above sea level. Within three miles the land runs from 1,410 ft to 1,910 ft, a difference of 500 ft: hilly country. The highest named summit within 15 miles is Bear Knob, about 2,370 ft, 15 miles east.
Under the town center the state geologic map shows Allegheny Formation (sandstone), from the Carboniferous, 299 to 324 million years old.
The section below crosses 5 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.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 16 mi of the line.
Shale, siltstone, sandstone. Age: Carboniferous, 324 to 359 million years old. About 4 mi of the line.
Sandstone. Age: Carboniferous, 324 to 359 million years old. About 2 mi of the line.
Sandstone, conglomerate. Age: Carboniferous, 299 to 324 million years old. About 1 mi of the line.
Shale. Age: Carboniferous, 299 to 324 million years old. About 0.3 mi of the line.

A raindrop that lands in Hawk Run reaches Chesapeake Bay and the Atlantic Ocean by way of Moshannon Creek, the West Branch Susquehanna and the Susquehanna: about 300 river miles.
Lake on the way: Lake Aldred.
140 miles of the trip are on the West Branch Susquehanna.

Hawk Run 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 Hawk Run 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, 20 miles east-southeast, 290 ft lower. NOAA, through RCC-ACIS.
