The Dawson 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.
18° on Nov. 15, 1969, the coldest reading for this week of the year since 1892. Next is 22° in 1963.
Dawson’s center stands about 350 ft above sea level. Within three miles the land runs from 300 ft to 410 ft, a difference of 110 ft: gently rolling country.
Under the town center the state geologic map shows Eocene and Oligocene Residuum, undifferentiated (sand, clay), from the Eocene to Oligocene, 23 to 56 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, clay. Age: Eocene to Oligocene, 23 to 56 million years old. About 18 mi of the line.
Limestone. Age: Eocene, 34 to 56 million years old. About 6 mi of the line.
Sandstone, shale. Age: Eocene, 34 to 56 million years old. About 0.8 mi of the line.

A raindrop that lands in Dawson reaches the Gulf of America by way of Brantley Creek, Chickasawhatchee Creek, Ichawaynochaway Creek, the Flint and the Apalachicola: about 220 river miles.
110 miles of the trip are on the Apalachicola.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Dawson; river miles along the main stem, rounded.
Dawson has a humid subtropical climate. Summer afternoons average 93° in July; winter nights fall to about 39° in January. About 47 inches of rain fall in a normal year.
On November 14 Dawson normally reaches 72° and falls to 46°. The record high is 87°, in 1955; the record low 23°, in 1968. The most rain on this date, 2.59 in, fell in 1940.
