Edgewater Park’s center stands about 1,260 ft above sea level. Within three miles the land runs from 1,190 ft to 1,380 ft, a difference of 190 ft: gently rolling country. The highest named summit within 15 miles is Mount Scott, about 2,450 ft, 10 miles west-southwest.
Under the town center the state geologic map shows Hennessey Group (shale), from the Permian, 252 to 299 million years old.
The section below crosses 11 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 34×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale. Age: Permian, 252 to 299 million years old. About 6 mi of the line.
Sandstone. Age: Permian, 252 to 299 million years old. About 4 mi of the line.
Conglomerate. Age: Permian, 252 to 299 million years old. About 3 mi of the line.
Limestone, dolostone, sandstone. Age: Early Ordovician, 471 to 487 million years old. About 2 mi of the line.
Shale, gypsum, dolostone. Age: Permian, 252 to 299 million years old. About 2 mi of the line.
Rhyolite. Age: Middle Cambrian, 497 to 521 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 5 smaller units along the line are not listed.

A raindrop that lands in Edgewater Park reaches the Gulf of America by way of Lake Ellsworth, East Cache Creek, Cache Creek, the Red River, the Atchafalaya and the Lower Atchafalaya: about 1,110 river miles.
Lake on the way: Lake Ellsworth.
880 miles of the trip are on the Red River.

Edgewater Park has a humid subtropical climate. Summer afternoons average 97° in July; winter nights fall to about 27° in January. About 28 inches of rain fall in a normal year.
On November 14 Edgewater Park normally reaches 65° and falls to 39°. The record high is 86°, in 2025; the record low 12°, in 1916. The most rain on this date, 1.31 in, fell in 1923.
