Edgar’s center stands about 1,730 ft above sea level. Within three miles the land runs from 1,670 ft to 1,740 ft, a difference of 70 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 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.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 22 mi of the line.
Limestone, shale. Age: Late Cretaceous, 66 to 100 million years old. About 3 mi of the line.

A raindrop that lands in Edgar reaches the Gulf of America by way of South Fork Big Sandy Creek, Big Sandy Creek, the Little Blue, the Big Blue, the Kansas, the Missouri and the Mississippi: about 1,880 river miles.
Lake on the way: Tuttle Creek Lake.
1,170 miles of the trip are on the Mississippi.

Edgar has a hot-summer humid continental climate. Summer afternoons average 87° in July; winter nights fall to about 16° in January. A normal year brings about 18 inches of snow; with the rain, that comes to about 30 inches of water.
On November 14 Edgar normally reaches 52° and falls to 29°. The record high is 80°, in 1999; the record low 10°, in 2022. The most rain on this date, 0.63 in, fell in 1972.
