Concord’s center stands about 1,450 ft above sea level. Within three miles the land runs from 1,410 ft to 1,590 ft, a difference of 180 ft: gently rolling country.
Under the town center the state geologic map shows Carlile Shale, from the Late Cretaceous, 66 to 100 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.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 15 mi of the line.
Limestone, shale. Age: Late Cretaceous, 66 to 100 million years old. About 9 mi of the line.

A raindrop that lands in Concord reaches the Gulf of America by way of North Logan Creek, the Logan Creek Dredge, the Elkhorn, the Platte, the Missouri and the Mississippi: about 1,910 river miles.
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 Concord; river miles along the main stem, rounded.
