−3° on Nov. 17, 1959, the coldest reading for this week of the year since 1893. Next is −3° in 1986.
Hallie’s center stands about 940 ft above sea level. Within three miles the land runs from 900 ft to 1,130 ft, a difference of 230 ft: rolling country. The highest named summit within 15 miles is Moldenhauer Hill, about 1,150 ft, 12 miles south-southeast.
Under the town center the state geologic map shows Cambrian, undivided (sandstone), from the Cambrian, 487 to 542 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 54×. 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: Cambrian, 487 to 542 million years old. About 21 mi of the line.
Granite. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 2 mi of the line.
Metagabbro. Age: Neoarchean, 2.5 to 2.8 billion years old. About 1 mi of the line.

Hallie has a warm-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 6° in January. A normal year brings about 55 inches of snow; with the rain, that comes to about 33 inches of water.
On November 14 Hallie normally reaches 43° and falls to 25°. The record high is 70°, in 1990; the record low 0°, in 1959. The most rain on this date, 1.12 in, fell in 1902.
