4.23 inches of rain fell in two days, the most for this week of the year since records began in 1893. The next wettest, 3.75 inches, fell in 1992.
Murphys Estates’s center stands about 560 ft above sea level. Within three miles the land runs from 330 ft to 580 ft, a difference of 250 ft: rolling country.
Under the town center the state geologic map shows Huber/Lisbon/Barnwell Formations, undivided (clay, sand), from the Eocene, 34 to 56 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 33×. 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: Eocene, 34 to 56 million years old. About 13 mi of the line.
Sand, clay. Age: Cretaceous to Tertiary, 2.6 to 145 million years old. About 4 mi of the line.
Metasedimentary, metavolcanic. Age: Neoproterozoic to Ordovician, 445 to 1,000 million years old. About 2 mi of the line.
