89° on Nov. 16, 2016, the hottest reading for this week of the year since 1893. Next is 88° in 1911.
Mulhall’s center stands about 1,120 ft above sea level. Within three miles the land runs from 980 ft to 1,140 ft, a difference of 160 ft: gently rolling country.
Under the town center the state geologic map shows Wellington Formation (shale, sandstone, conglomerate), from the Permian, 252 to 299 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 60×. 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, sandstone, conglomerate. Age: Permian, 252 to 299 million years old. About 19 mi of the line.
Fine-detrital. Age: Holocene, less than 12,000 years old. About 3 mi of the line.
Sandstone, conglomerate. Age: Permian, 252 to 299 million years old. About 1 mi of the line.
Coarse-detrital, fine-detrital. Age: Pleistocene, less than 2.6 million years old. About 0.6 mi of the line.

A raindrop that lands in Mulhall reaches the Gulf of America by way of Lake Carl Blackwell, Stillwater Creek, the Cimarron, the Arkansas and the Mississippi: about 1,210 river miles.
Lakes on the way: Murray Lake, Ozark Lake and Lake Carl Blackwell.
600 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Mulhall; river miles along the main stem, rounded.
Mulhall has a humid subtropical climate. Summer afternoons average 95° in July; winter nights fall to about 27° in January. About 33 inches of rain fall in a normal year.
On November 14 Mulhall normally reaches 63° and falls to 38°. The record high is 81°, in 2020; the record low 10°, in 1959. The most rain on this date, 2.50 in, fell in 1909.
