80° on Nov. 16, 2016, the hottest reading for this week of the year since 1960. Next is 79° in 1971.
New Strawn’s center stands about 1,120 ft above sea level. Within three miles the land runs from 1,020 ft to 1,170 ft, a difference of 150 ft: gently rolling country.
Under the town center the state geologic map shows Shawnee Group (limestone, shale), from the Carboniferous, 299 to 324 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 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone, shale. Age: Carboniferous, 299 to 324 million years old. About 17 mi of the line.
Sand, silt, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 5 mi of the line.
Gravel. Age: Tertiary, 2.6 to 66 million years old. About 3 mi of the line.

A raindrop that lands in New Strawn reaches the Gulf of America by way of the Neosho, the Arkansas and the Mississippi: about 1,330 river miles.
Lakes on the way: Murray Lake and Ozark Lake.
600 miles of the trip are on the Mississippi.
