Rushville’s center stands about 3,740 ft above sea level. Within three miles the land runs from 3,660 ft to 3,820 ft, a difference of 160 ft: gently rolling country. The highest named summit within 15 miles is Rattlesnake Peak, about 3,920 ft, 15 miles north.
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.
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 41×. 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 13 mi of the line.
Sand, volcanic. Age: Late Oligocene to Miocene, 5.3 to 28 million years old. About 11 mi of the line.

A raindrop that lands in Rushville reaches the Gulf of America by way of Rush Creek, the Niobrara, the Missouri and the Mississippi: about 2,310 river miles.
Lake on the way: Lewis and Clark Lake.
1,170 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Rushville; river miles along the main stem, rounded.
