Drammen’s center stands about 1,950 ft above sea level. Within three miles the land runs from 1,800 ft to 1,980 ft, a difference of 180 ft: gently rolling country.
Under the town center the state geologic map shows Undifferentiated (conglomerate, sandstone, mudstone), from the Late Cretaceous, 72 to 100 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 56×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Conglomerate, sandstone, mudstone. Age: Late Cretaceous, 72 to 100 million years old. About 14 mi of the line.
Quartzite. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 9 mi of the line.
Quartzite, mudstone. Age: Paleoproterozoic, 1.6 to 2 billion years old. About 0.9 mi of the line.

A raindrop that lands in Drammen reaches the Gulf of America by way of Norwegian Creek, Coon Creek, the Redwood, the Minnesota and the Mississippi: about 2,160 river miles.
Lakes on the way: Lake Pepin and Lake Benton.
1,750 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Drammen; river miles along the main stem, rounded.
Drammen has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 3° in January. A normal year brings about 36 inches of snow; with the rain, that comes to about 25 inches of water.
On November 14 Drammen normally reaches 42° and falls to 22°. The record high is 74°, in 1999; the record low −17°, in 1959. The most rain on this date, 0.39 in, fell in 1983.
