89° on Nov. 15, 2025, the hottest reading for this week of the year since 1923. Next is 88° in 1980.
Eden’s center stands about 2,060 ft above sea level. Within three miles the land runs from 1,980 ft to 2,140 ft, a difference of 160 ft: gently rolling country.
Under the town center the state geologic map shows Edwards Limestone, from the Early Cretaceous, 100 to 113 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 29×. 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: Early Cretaceous, 100 to 113 million years old. About 18 mi of the line.
Limestone, shale. Age: Permian, 252 to 299 million years old. About 3 mi of the line.
Shale. Age: Permian, 252 to 299 million years old. About 2 mi of the line.
Shale. Age: Permian, 252 to 299 million years old. About 1 mi of the line.
Coarse-detrital, fine-detrital. Age: Quaternary, less than 2.6 million years old. About 0.4 mi of the line.

A raindrop that lands in Eden reaches the Gulf of America by way of Harden Branch, Brady Creek, the San Saba and the Colorado: about 590 river miles.
Lakes on the way: Buchanan Lake, Lake Marble Falls and Lake Lyndon B Johnson.
320 miles of the trip are on the Colorado.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Eden; river miles along the main stem, rounded.
Eden has a humid subtropical climate. Summer afternoons average 95° in August; winter nights fall to about 31° in January. About 26 inches of rain fall in a normal year.
On November 14 Eden normally reaches 67° and falls to 41°. The record high is 85°, in 1955; the record low 16°, in 1940. The most rain on this date, 2.57 in, fell in 2004.
