3.70 inches of rain fell in two days, the most for this week of the year since records began in 1888. The next wettest, 3.52 inches, fell in 1957.
Phillipstown’s center stands about 500 ft above sea level. Within three miles the land runs from 360 ft to 520 ft, a difference of 160 ft: gently rolling country.
Under the town center the state geologic map shows Mattoon Formation (shale), from the Late Pennsylvanian, 304 to 307 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 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, sandstone, limestone. Age: Late Pennsylvanian, 304 to 307 million years old. About 9 mi of the line.
Shale. Age: Late Pennsylvanian, 304 to 307 million years old. About 8 mi of the line.
Shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 7 mi of the line.

A raindrop that lands in Phillipstown reaches the Gulf of America by way of the Fox River, the Wabash River Old Channel, the Old Channel Wabash, the Ohio and the Mississippi: about 1,160 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 Phillipstown; river miles along the main stem, rounded.
Phillipstown has a humid subtropical climate. Summer afternoons average 88° in July; winter nights fall to about 23° in January. A normal year brings about 8 inches of snow; with the rain, that comes to about 47 inches of water.
On November 14 Phillipstown normally reaches 57° and falls to 36°. The record high is 83°, in 1955; the record low 12°, in 1986. The most rain on this date, 2.64 in, fell in 1957.
