88° on Nov. 12, 2015, the hottest reading for this week of the year since 1958. Next is 87° in 2002.
Coleman’s center stands about 80 ft above sea level. Within three miles the land runs from 40 ft to 120 ft, a difference of 80 ft: gently rolling country.
Under the town center the state geologic map shows Ocala Limestone, from the Late Eocene, 34 to 38 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.
Limestone. Age: Late Eocene, 34 to 38 million years old. About 13 mi of the line.
Sand. Age: Holocene, less than 12,000 years old. About 4 mi of the line.
Sand. Age: Late Pliocene, 2.6 to 3.6 million years old. About 4 mi of the line.
Sand, clay. Age: Pliocene to Pleistocene, less than 5.3 million years old. About 3 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Coleman reaches the Gulf of America by way of Shady Brook and the Withlacoochee: about 65 river miles.
Lakes on the way: Lake Rousseau and Panasoffkee, Lake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Coleman; river miles along the main stem, rounded.
Coleman has a humid subtropical climate. Summer afternoons average 92° in August; winter nights fall to about 49° in January. About 44 inches of rain fall in a normal year.
On November 14 Coleman normally reaches 77° and falls to 57°. The record high is 87°, in 2018; the record low 33°, in 1963. The most rain on this date, 2.20 in, fell in 1972.
