84° on Nov. 16, 2025, the hottest reading for this week of the year since 1947. Next is 83° in 2016.
Lehigh’s center stands about 600 ft above sea level. Within three miles the land runs from 560 ft to 700 ft, a difference of 140 ft: gently rolling country. The highest named summit within 15 miles is Flagpole Mountain, about 900 ft, 4 miles west-southwest.
Under the town center the state geologic map shows McAlester Formation (shale, sandstone), from the Carboniferous, 299 to 324 million years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 59×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Fine-detrital. Age: Holocene, less than 12,000 years old. About 7 mi of the line.
Shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 6 mi of the line.

Sandstone. Age: Carboniferous, 299 to 324 million years old. About 0.9 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.

A raindrop that lands in Lehigh reaches the Gulf of America by way of Brier Creek, Muddy Boggy Creek, the Red River, the Atchafalaya and the Lower Atchafalaya: about 830 river miles.
590 miles of the trip are on the Red River.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lehigh; river miles along the main stem, rounded.
Lehigh has a humid subtropical climate. Summer afternoons average 93° in August; winter nights fall to about 28° in January. About 46 inches of rain fall in a normal year, with about 3 inches of snow.
