Cedar Rapids’s center stands about 1,780 ft above sea level. Within three miles the land runs from 1,740 ft to 1,940 ft, a difference of 200 ft: gently rolling country. The highest named summit within 15 miles is Pilot Knob, about 1,970 ft, 5 miles 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 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.
Siltstone-mudstone, conglomerate-sandstone. Age: Miocene, 5.3 to 23 million years old. About 24 mi of the line.

A raindrop that lands in Cedar Rapids reaches the Gulf of America by way of the Cedar River, the Loup, the Platte, the Missouri and the Mississippi: about 1,930 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 Cedar Rapids; river miles along the main stem, rounded.
Cedar Rapids has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 11° in January. A normal year brings about 27 inches of snow; with the rain, that comes to about 27 inches of water.
On November 14 Cedar Rapids normally reaches 49° and falls to 25°. The record high is 75°, in 1956; the record low −15°, in 1916. The most rain on this date, 0.49 in, fell in 1926.
