The Plainview 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.
Plainview’s center stands about 1,690 ft above sea level. Within three miles the land runs from 1,660 ft to 1,790 ft, a difference of 130 ft: gently rolling country. The highest named summit within 15 miles is Council Hill, about 1,850 ft, 11 miles west-northwest.
Under the town center the state geologic map shows Ogallala Group or Formation (siltstone-mudstone, conglomerate-sandstone), from the Miocene, 5.3 to 23 million years old.
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.
Siltstone-mudstone, conglomerate-sandstone. Age: Miocene, 5.3 to 23 million years old. About 24 mi of the line.

A raindrop that lands in Plainview reaches the Gulf of America by way of Dry Creek, the North Fork Elkhorn, the Elkhorn, the Platte, the Missouri and the Mississippi: about 1,970 river miles.
1,170 miles of the trip are on the Mississippi.
