74° on Nov. 11, 2024, the hottest reading for this week of the year since 1978. Next is 72° in 1993.
Lincoln University’s center stands about 530 ft above sea level. Within three miles the land runs from 370 ft to 630 ft, a difference of 260 ft: rolling country. The highest named summit within 15 miles is Gap Hill, about 880 ft, 13 miles north-northwest.
Under the town center the state geologic map shows "Glenarm Wissahickon" formation (mica-schist), from the Paleozoic, 252 to 542 million years old.
The section below crosses 9 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 28×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Mica-schist. Age: Paleozoic, 252 to 542 million years old. About 9 mi of the line.
Mica-schist, quartzite. Age: Paleozoic, 252 to 542 million years old. About 5 mi of the line.
Gneiss, quartz-diorite, granodiorite. Age: Neoproterozoic to Middle Cambrian, 500 to 600 million years old. About 3 mi of the line.
Muscovite-schist. Age: Proterozoic, 542 to 2,500 million years old. About 2 mi of the line.
Gneiss. Age: Precambrian. About 1 mi of the line.
Schist, phyllite. Age: Paleozoic, 252 to 542 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. 3 smaller units along the line are not listed.

A raindrop that lands in Lincoln University reaches Chesapeake Bay and the Atlantic Ocean by way of McDonald Run, West Branch Big Elk Creek, Big Elk Creek and the Elk River: about 40 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lincoln University; river miles along the main stem, rounded.
Lincoln University has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 22° in January. A normal year brings about 18 inches of snow; with the rain, that comes to about 48 inches of water.
On November 14 Lincoln University normally reaches 54° and falls to 33°. The record high is 72°, in 1993; the record low 15°, in 2022. The most rain on this date, 0.92 in, fell in 1995.
Normals 1991–2020 and records since 1978 at Octoraro Lake, 6 miles west, 270 ft lower. NOAA, through RCC-ACIS.
