5.85 inches of rain fell in two days, the most for this week of the year since records began in 1910. The next wettest, 2.95 inches, fell in 1957.
Garland’s center stands about 140 ft above sea level. Within three miles the land runs from 50 ft to 150 ft, a difference of 100 ft: gently rolling country.
Under the town center the state geologic map shows Black Creek Formation (clay, sand), from the Cretaceous, 66 to 145 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: Cretaceous, 66 to 145 million years old. About 24 mi of the line.

A raindrop that lands in Garland reaches the Atlantic Ocean by way of the South River, the Black River and the Cape Fear: about 100 river miles.
