5.29 inches of rain fell in two days, the most for this week of the year since records began in 1892. The next wettest, 4.41 inches, fell in 1951.
Lockhart’s center stands about 100 ft above sea level. Within three miles the land runs from 60 ft to 140 ft, a difference of 80 ft: gently rolling country.
Under the town center the state geologic map shows Cypresshead Formation (sand), from the Late Pliocene, 2.6 to 3.6 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.
Sand. Age: Late Pliocene, 2.6 to 3.6 million years old. About 16 mi of the line.
Sand, clay. Age: Middle Miocene to Late Miocene, 5.3 to 16 million years old. About 7 mi of the line.
Sand, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 2 mi of the line.

A raindrop that lands in Lockhart reaches the St. Johns River and the Atlantic Ocean by way of the Little Wekiva, the Wekiva, Blue Creek and Trout Creek: about 190 river miles.
Lake on the way: George, Lake.
100 miles of the trip are on Trout Creek.
