22° on Nov. 15, 1963, the coldest reading for this week of the year since 1956. Next is 24° in 1969.
Du Pont’s center stands about 200 ft above sea level. Within three miles the land runs from 180 ft to 230 ft, a difference of 50 ft: nearly flat ground.
Under the town center the state geologic map shows Pleistocene-Pliocene sands and gravels (sand, gravel), from the Pliocene to Pleistocene, less than 5.3 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.
Sand, gravel. Age: Pliocene to Pleistocene, less than 5.3 million years old. About 23 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
