77° on Nov. 15, 1973, the hottest reading for this week of the year since 1956. Next is 76° in 2020.
Freedom’s center stands about 540 ft above sea level. Within three miles the land runs from 430 ft to 720 ft, a difference of 290 ft: rolling country. The highest named summit within 15 miles is Quirauk Mountain, about 2,150 ft, 12 miles west-southwest.
Under the town center the state geologic map shows Gettysburg Formation (siltstone-mudstone, shale), from the Triassic, 202 to 252 million years old.
The section below crosses 13 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.
Siltstone-mudstone, shale. Age: Triassic, 202 to 252 million years old. About 5 mi of the line.
Basalt. Age: Jurassic, 145 to 202 million years old. About 4 mi of the line.
Sandstone, shale. Age: Triassic, 202 to 252 million years old. About 4 mi of the line.
Quartzite. Age: Cambrian, 487 to 542 million years old. About 3 mi of the line.
Age: Precambrian. About 2 mi of the line.
Conglomerate. Age: Triassic, 202 to 252 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. 7 smaller units along the line are not listed.

A raindrop that lands in Freedom reaches Chesapeake Bay and the Atlantic Ocean by way of Marsh Creek, the Monocacy and the Potomac: about 220 river miles.
160 miles of the trip are on the Potomac.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Freedom; river miles along the main stem, rounded.
Freedom has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 22° in January. A normal year brings about 28 inches of snow; with the rain, that comes to about 47 inches of water.
On November 14 Freedom normally reaches 55° and falls to 34°. The record high is 72°, in 1989; the record low 15°, in 1986. The most rain on this date, 2.25 in, fell in 1972.
Normals 1991–2020 and records since 1956 at Emmitsburg 2 SE, 6 miles south, 140 ft lower. NOAA, through RCC-ACIS.
