5.00 inches of rain fell in two days, the most for this week of the year since records began in 1893. The next wettest, 4.25 inches, fell in 1929.
Runnelstown’s center stands about 160 ft above sea level. Within three miles the land runs from 140 ft to 280 ft, a difference of 140 ft: gently rolling country.
Under the town center the state geologic map shows Pascagoula and Hattiesburg formation (clay, sand), from the Miocene, 5.3 to 23 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.
Clay, sand. Age: Miocene, 5.3 to 23 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.

A raindrop that lands in Runnelstown reaches the Gulf of America by way of Tallahala Creek, the Leaf, the Pascagoula and the West Pascagoula: about 140 river miles.
65 miles of the trip are on the Pascagoula.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Runnelstown; river miles along the main stem, rounded.
