5.46 inches of rain fell in two days, the most for this week of the year since records began in 1919. The next wettest, 2.99 inches, fell in 2019.
Lawtey’s center stands about 160 ft above sea level. Within three miles the land runs from 140 ft to 250 ft, a difference of 110 ft: gently rolling country.
Under the town center the state geologic map shows Undifferentiated sediments (sand, clay), from the Pliocene to Pleistocene, less than 5.3 million years old.
The section below crosses 4 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, clay. Age: Pliocene to Pleistocene, less than 5.3 million years old. About 12 mi of the line.
Sand. Age: Pleistocene, less than 2.6 million years old. About 6 mi of the line.
Sand. Age: Late Pliocene, 2.6 to 3.6 million years old. About 5 mi of the line.
Sand, clay. Age: Middle Miocene to Late Miocene, 5.3 to 16 million years old. About 2 mi of the line.

A raindrop that lands in Lawtey reaches the Gulf of America by way of Alligator Creek, the New River, the Santa Fe and the Suwannee: about 140 river miles.
65 miles of the trip are on the Suwannee.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lawtey; river miles along the main stem, rounded.
Lawtey has a humid subtropical climate. Summer afternoons average 93° in July; winter nights fall to about 40° in January. About 53 inches of rain fall in a normal year.
On November 14 Lawtey normally reaches 75° and falls to 49°. The record high is 85°, in 2018; the record low 27°, in 1963. The most rain on this date, 2.57 in, fell in 1949.
Normals 1991–2020 and records since 1919 at Glen St Mary 1 W, 17 miles north-northwest. NOAA, through RCC-ACIS.
