The Bloomingdale plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
85° on Nov. 15, 1956, the hottest reading for this week of the year since 1878. Next is 78° in 1958.
Bloomingdale’s center stands about 1,240 ft above sea level. Within three miles the land runs from 890 ft to 1,300 ft, a difference of 410 ft: hilly country.
Under the town center the state geologic map shows Monongahela Group (shale, siltstone, mudstone), 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 29×. 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, siltstone, mudstone. Age: Carboniferous, 299 to 324 million years old. About 14 mi of the line.
Shale, siltstone, mudstone. Age: Carboniferous, 299 to 324 million years old. About 9 mi of the line.
Fine-detrital, coarse-detrital. Age: Quaternary, less than 2.6 million years old. About 0.4 mi of the line.

A raindrop that lands in Bloomingdale reaches the Gulf of America by way of McIntyre Creek, Cross Creek, the Ohio and the Mississippi: about 1,890 river miles.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Bloomingdale; river miles along the main stem, rounded.
Bloomingdale has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 22° in January. About 38 inches of rain fall in a normal year.
On November 14 Bloomingdale normally reaches 52° and falls to 36°. The record high is 74°, in 1989; the record low 10°, in 1920. The most rain on this date, 1.10 in, fell in 1997.
