Lake Hallie’s center stands about 900 ft above sea level. Within three miles the land runs from 790 ft to 1,100 ft, a difference of 310 ft: rolling country. The highest named summit within 15 miles is Elk Mound, about 1,210 ft, 12 miles west.
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 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 39×. 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 23 mi of the line.
Metagabbro. Age: Neoarchean, 2.5 to 2.8 billion years old. About 2 mi of the line.

A raindrop that lands in Lake Hallie reaches the Gulf of America by way of the Chippewa and the Mississippi: about 1,810 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lake Hallie; river miles along the main stem, rounded.
Lake 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 Lake 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.
