The Deerfield plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
−5° on Nov. 16, 1955, the coldest reading for this week of the year since 1893. Next is −2° in 1940.
Deerfield’s center stands about 2,960 ft above sea level. Within three miles the land runs from 2,920 ft to 3,020 ft, a difference of 100 ft: gently rolling country.
Under the town center the state geologic map shows Loess (silt), from the Pleistocene to Holocene, less than 2.6 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 48×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Silt. Age: Pleistocene to Holocene, less than 2.6 million years old. About 12 mi of the line.
Sand, silt, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 11 mi of the line.
Sand, silt, clay. Age: Pleistocene, less than 2.6 million years old. About 0.3 mi of the line.

A raindrop that lands in Deerfield reaches the Gulf of America by way of the Arkansas and the Mississippi: about 1,600 river miles.
Lakes on the way: Murray Lake and Ozark Lake.
710 miles of the trip are on the Arkansas.

Deerfield has a cold semi-arid climate. Summer afternoons average 94° in July; winter nights fall to about 20° in January. A normal year brings about 19 inches of snow; with the rain, that comes to about 19 inches of water.
On November 14 Deerfield normally reaches 58° and falls to 29°. The record high is 83°, in 1999; the record low −1°, in 1940. The most rain on this date, 0.57 in, fell in 1926.
