The Iowa Park 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.
92° on Nov. 15, 2025, the hottest reading for this week of the year since 1897. Next is 87° in 2021.
Iowa Park’s center stands about 1,040 ft above sea level. Within three miles the land runs from 970 ft to 1,100 ft, a difference of 130 ft: gently rolling country. The highest named summit within 15 miles is Sunshine Hill, about 1,200 ft, 11 miles northwest.
Under the town center the state geologic map shows Petrolia Formation (shale), from the Permian, 252 to 299 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.
Shale. Age: Permian, 252 to 299 million years old. About 8 mi of the line.
Siltstone-mudstone. Age: Permian, 252 to 299 million years old. About 8 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 7 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 1 mi of the line.

A raindrop that lands in Iowa Park reaches the Gulf of America by way of Buffalo Creek, the Wichita, the Red River, the Atchafalaya and the Lower Atchafalaya: about 1,090 river miles.
870 miles of the trip are on the Red River.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Iowa Park; river miles along the main stem, rounded.
Iowa Park has a humid subtropical climate. Summer afternoons average 97° in July; winter nights fall to about 30° in January. About 28 inches of rain fall in a normal year, with about 3 inches of snow.
On November 14 Iowa Park normally reaches 66° and falls to 41°. The record high is 88°, in 2025; the record low 19°, in 1940. The most rain on this date, 0.92 in, fell in 1947.
