Havre North’s center stands about 2,560 ft above sea level. Within three miles the land runs from 2,470 ft to 2,790 ft, a difference of 320 ft: rolling country. The highest named summit within 15 miles is Brindle Calf Woman Butte, about 3,820 ft, 12 miles south-southeast.
Under the town center the state geologic map shows Judith River Formation (sandstone, shale), from the Late Cretaceous, 72 to 84 million years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 16×. 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, shale. Age: Late Cretaceous, 72 to 84 million years old. About 16 mi of the line.
Mafic-volcanic. Age: Tertiary, 2.6 to 66 million years old. About 4 mi of the line.
Felsic-volcanic. Age: Tertiary, 2.6 to 66 million years old. About 3 mi of the line.
Shale. Age: Late Cretaceous, 72 to 84 million years old. About 0.6 mi of the line.

A raindrop that lands in Havre North reaches the Gulf of America by way of the Milk River, the Missouri and the Mississippi: about 3,340 river miles.
Lakes on the way: Lake Oahe, Lake Sakakawea, Lake Sharpe and Lake Francis Case.
1,170 miles of the trip are on the Mississippi.

Havre North has a cold semi-arid climate. Summer afternoons average 86° in July; winter nights fall to about 7° in January. A normal year brings about 41 inches of snow; with the rain, that comes to about 12 inches of water.
On November 14 Havre North normally reaches 42° and falls to 20°. The record high is 71°, in 1999; the record low −19°, in 2014. The most rain on this date, 0.30 in, fell in 1903.
