79° on Nov. 17, 2016, the hottest reading for this week of the year since 1951. Next is 76° in 1964.
Wheaton’s center stands about 1,510 ft above sea level. Within three miles the land runs from 1,300 ft to 1,520 ft, a difference of 220 ft: rolling country.
Under the town center the state geologic map shows Drift (sand, silt), from the Pleistocene, 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 39×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

A raindrop that lands in Wheaton reaches the Gulf of America by way of the Clear Fork, the Black Vermillion, the Big Blue, the Kansas, the Missouri and the Mississippi: about 1,760 river miles.
Lake on the way: Tuttle Creek Lake.
1,170 miles of the trip are on the Mississippi.
