83° on Nov. 11, 1989, the hottest reading for this week of the year since 1896. Next is 83° in 1999.
Attica’s center stands about 1,460 ft above sea level. Within three miles the land runs from 1,370 ft to 1,520 ft, a difference of 150 ft: gently rolling country.
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 44×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sand, silt, clay. Age: Pleistocene, less than 2.6 million years old. About 15 mi of the line.
Siltstone, sandstone, shale. Age: Permian, 252 to 299 million years old. About 8 mi of the line.
Sand, silt, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.8 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Attica reaches the Gulf of America by way of Camp Creek, Sandy Creek, the Salt Fork Arkansas, the Arkansas and the Mississippi: about 1,340 river miles.
Lakes on the way: Great Salt Plains Reservoir, Murray Lake and Ozark Lake.
600 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Attica; river miles along the main stem, rounded.
Attica has a humid subtropical climate. Summer afternoons average 93° in July; winter nights fall to about 22° in January. A normal year brings about 11 inches of snow; with the rain, that comes to about 33 inches of water.
On November 14 Attica normally reaches 58° and falls to 35°. The record high is 77°, in 1973; the record low 9°, in 1940. The most rain on this date, 2.80 in, fell in 1931.
Normals 1991–2020 and records since 1896 at Anthony, 13 miles east-southeast, 100 ft lower. NOAA, through RCC-ACIS.
