71° on Nov. 14, 1939, the hottest reading for this week of the year since 1909. Next is 69° in 2005.
Grace City’s center stands about 1,510 ft above sea level. Within three miles the land runs from 1,450 ft to 1,570 ft, a difference of 120 ft: gently rolling country. The highest named summit within 15 miles is Devils Thumb, about 1,730 ft, 12 miles northeast.
Under the town center the state geologic map shows Pierre Formation (shale), from the Late Cretaceous, 66 to 100 million years old.
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 24 mi of the line.

A raindrop that lands in Grace City reaches the Gulf of America by way of the James, the Missouri and the Mississippi: about 2,610 river miles.
Lakes on the way: Columbia Road Reservoir and Depuy Dam 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 Grace City; river miles along the main stem, rounded.
Grace City has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about −1° in January. A normal year brings about 60 inches of snow; with the rain, that comes to about 21 inches of water.
