Upham’s center stands about 1,450 ft above sea level. Within three miles the land runs from 1,410 ft to 1,460 ft, a difference of 50 ft: nearly flat ground.
Under the town center the state geologic map shows Fox Hills Formation (shale, sandstone), from the Late Cretaceous, 66 to 100 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 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.
Shale, sandstone. Age: Late Cretaceous, 66 to 100 million years old. About 23 mi of the line.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Upham reaches Hudson Bay by way of Cut Bank Creek, the Deep River, the Souris, the Assiniboine, the Red River of the North and the Nelson: about 1,020 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 Upham; river miles along the main stem, rounded.
