74° on Nov. 11, 2020, the hottest reading for this week of the year since 1964. Next is 70° in 1964.
Gallitzin’s center stands about 2,200 ft above sea level. Within three miles the land runs from 1,790 ft to 2,510 ft, a difference of 720 ft: hilly country. The highest named summit within 15 miles is Blue Knob, about 3,140 ft, 13 miles south.
Under the town center the state geologic map shows Glenshaw Formation (shale), from the Carboniferous, 299 to 324 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.
Shale, clastic. Age: Carboniferous, 299 to 324 million years old. About 8 mi of the line.
Shale. Age: Carboniferous, 299 to 324 million years old. About 6 mi of the line.
Limestone. Age: Silurian to Devonian, 359 to 445 million years old. About 2 mi of the line.
Shale, sandstone. Age: Silurian, 422 to 445 million years old. About 2 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 1 mi of the line.
Shale. Age: Silurian, 422 to 445 million years old. About 0.9 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 Gallitzin reaches Chesapeake Bay and the Atlantic Ocean by way of Bradley Run, Clearfield Creek, the West Branch Susquehanna and the Susquehanna: about 370 river miles.
Lake on the way: Lake Aldred.
170 miles of the trip are on the West Branch Susquehanna.

Gallitzin has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 16° in January. A normal year brings about 80 inches of snow; with the rain, that comes to about 49 inches of water.
On November 14 Gallitzin normally reaches 48° and falls to 29°. The record high is 69°, in 1994; the record low 5°, in 1986. The most rain on this date, 0.74 in, fell in 1993.
