Flaxton’s center stands about 1,930 ft above sea level. Within three miles the land runs from 1,910 ft to 1,950 ft, a difference of 40 ft: nearly flat ground.
Under the town center the state geologic map shows Bullion Creek Formation (claystone, siltstone), from the Paleocene, 56 to 66 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 35×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Claystone, siltstone. Age: Paleocene, 56 to 66 million years old. About 16 mi of the line.
Siltstone, claystone, sandstone. Age: Paleocene, 56 to 66 million years old. About 3 mi of the line.
Shale, sandstone. Age: Paleocene, 56 to 66 million years old. About 0.7 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 Flaxton reaches Hudson Bay by way of Stony Creek, the Des Lacs, the Souris, the Assiniboine, the Red River of the North and the Nelson: about 1,340 river miles. Past the border it runs north through Canada to Hudson Bay.
Lakes on the way: Upper Des Lacs Lake and 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 Flaxton; river miles along the main stem, rounded.
