The Nye 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.
Nye’s center stands about 4,830 ft above sea level. Within three miles the land runs from 4,740 ft to 7,240 ft, a difference of 2,500 ft: mountain country. The highest named summit within 15 miles is Mount Wood, about 12,550 ft, 11 miles south.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 2×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Andesite, conglomerate, sandstone. Age: Late Cretaceous, 66 to 84 million years old. About 10 mi of the line.
Gneiss. Age: Archean. About 6 mi of the line.
Unconsolidated. Age: Pleistocene to Holocene, less than 1.8 million years old. About 3 mi of the line.
Age: Archean. About 3 mi of the line.
Sandstone, sandstone-mudstone. Age: Late Cretaceous, 72 to 87 million years old. About 3 mi of the line.
Limestone, dolostone, black-shale. Age: Early Mississippian to Middle Mississippian, 331 to 359 million years old. About 0.3 mi of the line.

A raindrop that lands in Nye reaches the Gulf of America by way of the Stillwater, the Yellowstone, the Missouri and the Mississippi: about 3,190 river miles.
Lakes on the way: Lake Oahe, Lake Sakakawea, Lake Sharpe and Lake Francis Case.
1,170 miles of the trip are on the Mississippi.
