84° on Nov. 17, 2016, the hottest reading for this week of the year since 1953. Next is 82° in 2012.
Damar’s center stands about 2,120 ft above sea level. Within three miles the land runs from 1,970 ft to 2,230 ft, a difference of 260 ft: 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 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 37×. 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 10 mi of the line.
Arkose. Age: Miocene, 5.3 to 23 million years old. About 6 mi of the line.
Shale, limestone. Age: Late Cretaceous, 66 to 100 million years old. About 5 mi of the line.
Sand, silt, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 2 mi of the line.
Shale, chalk. Age: Late Cretaceous, 66 to 100 million years old. About 1 mi of the line.

A raindrop that lands in Damar reaches the Gulf of America by way of the South Fork Solomon, the Solomon, the Smoky Hill, the Kansas, the Missouri and the Mississippi: about 2,050 river miles.
Lake on the way: Waconda 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 Damar; river miles along the main stem, rounded.
Damar has a hot-summer humid continental climate. Summer afternoons average 94° in July; winter nights fall to about 16° in January. About 25 inches of rain fall in a normal year.
On November 14 Damar normally reaches 57° and falls to 28°. The record high is 79°, in 1990; the record low 0°, in 1986. The most rain on this date, 0.09 in, fell in 1972.
Normals 1991–2020 and records since 1953 at Webster Dam, 11 miles east-northeast, 260 ft lower. NOAA, through RCC-ACIS.
