91° on Nov. 12, 2003, the hottest reading for this week of the year since 1911. Next is 88° in 1938.
Sparks’s center stands about 250 ft above sea level. Within three miles the land runs from 230 ft to 310 ft, a difference of 80 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 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.
Clay, sand, gravel. Age: Tertiary Neogene, 2.6 to 23 million years old. About 20 mi of the line.
Dolostone, sand, clay. Age: Miocene, 5.3 to 23 million years old. About 4 mi of the line.

A raindrop that lands in Sparks reaches the Gulf of America by way of Giddens Mill Creek, Bear Creek, the Withlacoochee and the Suwannee: about 230 river miles.
130 miles of the trip are on the Suwannee.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Sparks; river miles along the main stem, rounded.
