83° on Nov. 13, 1999, the hottest reading for this week of the year since 1895. Next is 81° in 1956.
Baldwin City’s center stands about 1,070 ft above sea level. Within three miles the land runs from 920 ft to 1,150 ft, a difference of 230 ft: rolling country.
Under the town center the state geologic map shows Douglas Group (shale, sandstone), from the Carboniferous, 299 to 324 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 56×. 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 Baldwin City reaches the Gulf of America by way of East Fork Tauy Creek, Tauy Creek, Ottawa Creek, the Marais des Cygnes, the Osage, the Missouri and the Mississippi: about 1,720 river miles.
1,170 miles of the trip are on the Mississippi.
