The Calvary plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
22° on Nov. 16, 1940, the coldest reading for this week of the year since 1892. Next is 22° in 1969.
Calvary’s center stands about 270 ft above sea level. Within three miles the land runs from 180 ft to 310 ft, a difference of 130 ft: gently rolling country.
Under the town center the state geologic map shows Miccosukee Formation (clay, sand, gravel), from the Tertiary Neogene, 2.6 to 23 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.
Clay, sand, gravel. Age: Tertiary Neogene, 2.6 to 23 million years old. About 15 mi of the line.
Sandstone, limestone. Age: Middle Miocene, 12 to 16 million years old. About 5 mi of the line.
Sand, clay, gravel. Age: Late Pliocene, 2.6 to 3.6 million years old. About 3 mi of the line.
Dolostone, sand, clay. Age: Miocene, 5.3 to 23 million years old. About 2 mi of the line.

A raindrop that lands in Calvary reaches the Gulf of America by way of Shaw Creek and the Ochlockonee: about 110 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Calvary; river miles along the main stem, rounded.
Calvary has a humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 40° in January. About 59 inches of rain fall in a normal year.
On November 14 Calvary normally reaches 73° and falls to 48°. The record high is 85°, in 2005; the record low 26°, in 1977. The most rain on this date, 2.99 in, fell in 2008.
