The Manter 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.
2° on Nov. 13, 2014, the coldest reading for this week of the year since 1995. Next is 4° in 2019.
Manter’s center stands about 3,490 ft above sea level. Within three miles the land runs from 3,420 ft to 3,540 ft, a difference of 120 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 4 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.
Silt. Age: Pleistocene to Holocene, less than 2.6 million years old. About 19 mi of the line.
Sandstone, conglomerate. Age: Miocene to Pliocene, 2.6 to 23 million years old. About 3 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 1 mi of the line.
Arkose. Age: Miocene, 5.3 to 23 million years old. About 0.6 mi of the line.

A raindrop that lands in Manter reaches the Gulf of America by way of Bear Creek, the Arkansas and the Mississippi: about 1,680 river miles.
Lakes on the way: Murray Lake and Ozark Lake.
730 miles of the trip are on the Arkansas.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Manter; river miles along the main stem, rounded.
Manter 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 22 inches of snow; with the rain, that comes to about 18 inches of water.
On November 14 Manter normally reaches 59° and falls to 30°. The record high is 82°, in 2007; the record low 3°, in 2014. The most rain on this date, 0.22 in, fell in 2003.
