Hampden’s center stands about 800 ft above sea level. Within three miles the land runs from 790 ft to 820 ft, a difference of 30 ft: nearly flat ground.
Under the town center the state geologic map shows Upper Ordovician (limestone, dolostone), from the Late Ordovician, 445 to 459 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone, dolostone. Age: Late Ordovician, 445 to 459 million years old. About 17 mi of the line.
Limestone, dolostone. Age: Ordovician, 445 to 487 million years old. About 3 mi of the line.
Conglomerate, sandstone, mudstone. Age: Late Cretaceous, 72 to 100 million years old. About 2 mi of the line.
Shale, limestone, dolostone. Age: Jurassic, 145 to 202 million years old. About 2 mi of the line.

A raindrop that lands in Hampden reaches Hudson Bay by way of the North Branch Two Rivers, the Two Rivers, the Red River of the North and the Nelson: about 840 river miles. Past the border it runs north through Canada to Hudson Bay.
Lake on the way: Lake Winnipeg.
400 miles of the trip are on the Nelson.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Hampden; river miles along the main stem, rounded.
Hampden has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about −4° in January. About 22 inches of rain fall in a normal year.
On November 14 Hampden normally reaches 35° and falls to 19°. The record high is 65°, in 1953; the record low −19°, in 1919. The most rain on this date, 2.00 in, fell in 1944.
Normals 1991–2020 and records since 1899 at Hallock, 6 miles south-southeast. NOAA, through RCC-ACIS.
