9° on Nov. 16, 1933, the coldest reading for this week of the year since 1882. Next is 12° in 1883.
Pleasant Gap’s center stands about 1,010 ft above sea level. Within three miles the land runs from 870 ft to 2,150 ft, a difference of 1,280 ft: steep hill country. The highest named summit within 15 miles is Thickhead Mountain, about 2,420 ft, 9 miles south-southeast.
Under the town center the state geologic map shows Benner Formation through Loysburg Formation, undivided (limestone, dolostone), from the Ordovician, 445 to 487 million years old.
The section below crosses 15 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.
Dolostone. Age: Ordovician, 445 to 487 million years old. About 4 mi of the line.
Sandstone, shale. Age: Ordovician, 445 to 487 million years old. About 3 mi of the line.
Shale. Age: Ordovician, 445 to 487 million years old. About 3 mi of the line.
Sandstone, siltstone, shale. Age: Late Devonian, 359 to 384 million years old. About 3 mi of the line.
Sandstone, siltstone, mudstone. Age: Late Devonian, 359 to 384 million years old. About 2 mi of the line.
Limestone, dolostone. Age: Ordovician, 445 to 487 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. 9 smaller units along the line are not listed.

A raindrop that lands in Pleasant Gap reaches Chesapeake Bay and the Atlantic Ocean by way of Logan Branch, Spring Creek, 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.

Pleasant Gap 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 Pleasant Gap 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, 8 miles southwest, 160 ft higher. NOAA, through RCC-ACIS.
