Corn Creek’s center stands about 2,360 ft above sea level. Within three miles the land runs from 2,310 ft to 2,630 ft, a difference of 320 ft: rolling country. The highest named summit within 15 miles is Cedar Butte, about 2,770 ft, 6 miles northwest.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 33×. 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, sandstone. Age: Eocene to Oligocene, 23 to 56 million years old. About 11 mi of the line.
Siltstone, sandstone. Age: Oligocene to Miocene, 5.3 to 34 million years old. About 9 mi of the line.
Coarse-detrital, fine-detrital. Age: Quaternary, less than 2.6 million years old. About 2 mi of the line.
Coarse-detrital, clay. Age: Quaternary, less than 2.6 million years old. About 1 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 Corn Creek reaches the Gulf of America by way of Black Pipe Creek, the White River, the Missouri and the Mississippi: about 2,340 river miles.
Lakes on the way: Lake Francis Case and 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 Corn Creek; river miles along the main stem, rounded.
