67° on Nov. 15, 2025, the hottest reading for this week of the year since 1930. Next is 66° in 2001.
Michigan City’s center stands about 1,520 ft above sea level. Within three miles the land runs from 1,510 ft to 1,530 ft, a difference of 20 ft: nearly flat ground.
Under the town center the state geologic map shows Pierre Formation (shale), from the Late Cretaceous, 66 to 100 million years old.
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.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 24 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
