The Wildrose plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
Wildrose’s center stands about 2,260 ft above sea level. Within three miles the land runs from 2,200 ft to 2,350 ft, a difference of 150 ft: gently rolling country.
Under the town center the state geologic map shows Sentinel Butte Formation (siltstone, claystone, sandstone), from the Paleocene, 56 to 66 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 49×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Siltstone, claystone, sandstone. Age: Paleocene, 56 to 66 million years old. About 21 mi of the line.
Claystone, siltstone. Age: Paleocene, 56 to 66 million years old. About 3 mi of the line.
