The Silver Springs 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.
90° on Nov. 16, 1957, the hottest reading for this week of the year since 1892. Next is 89° in 1952.
Silver Springs’s center stands about 60 ft above sea level. Within three miles the land runs from 60 ft to 140 ft, a difference of 80 ft: gently rolling country.
Under the town center the state geologic map shows Undifferentiated sediments (sand, clay), from the Pleistocene to Holocene, less than 2.6 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: Pleistocene to Holocene, less than 2.6 million years old. About 15 mi of the line.
Sand, clay. Age: Middle Miocene to Late Miocene, 5.3 to 16 million years old. About 8 mi of the line.
Limestone. Age: Late Eocene, 34 to 38 million years old. About 1 mi of the line.

A raindrop that lands in Silver Springs reaches the St. Johns River and the Atlantic Ocean by way of the Silver, the Ocklawaha and Trout Creek: about 150 river miles.
Lake on the way: Lake Ocklawaha.
100 miles of the trip are on Trout Creek.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Silver Springs; river miles along the main stem, rounded.
Silver Springs has a humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 46° in January. About 52 inches of rain fall in a normal year.
On November 14 Silver Springs normally reaches 77° and falls to 54°. The record high is 87°, in 1945; the record low 28°, in 1932. The most rain on this date, 1.47 in, fell in 1941.
