3.55 inches of rain fell in two days, the most for this week of the year since records began in 1942. The next wettest, 2.43 inches, fell in 1994.
Pine Ridge’s center stands about 20 ft above sea level. Within three miles the land runs from 0 ft to 30 ft, a difference of 30 ft: nearly flat ground. Open water lies within three miles.
Under the town center the state geologic map shows Tamiami Formation (sand, limestone, clay), from the Late Pliocene, 2.6 to 3.6 million years old.
The section below crosses 2 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, limestone, clay. Age: Late Pliocene, 2.6 to 3.6 million years old. About 13 mi of the line.
Sand. Age: Holocene, less than 12,000 years old. About 0.9 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 Pine Ridge reaches the Gulf of America by way of the Gordon: about 2 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Pine Ridge; river miles along the main stem, rounded.
Pine Ridge has a humid subtropical climate. Summer afternoons average 91° in August; winter nights fall to about 52° in January. About 61 inches of rain fall in a normal year.
On November 14 Pine Ridge normally reaches 81° and falls to 60°. The record high is 91°, in 1993; the record low 39°, in 1968. The most rain on this date, 1.88 in, fell in 1969.
Normals 1991–2020 and records since 1942 at Naples, 8 miles east-southeast. NOAA, through RCC-ACIS.
