The Lockhart 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.
86° on Nov. 11, 2020, the hottest reading for this week of the year since 1948. Next is 85° in 2008.
Lockhart’s center stands about 310 ft above sea level. Within three miles the land runs from 240 ft to 340 ft, a difference of 100 ft: gently rolling country.
Under the town center the state geologic map shows Miocene Series undifferentiated (sand, clay), from the Miocene to Pliocene, 2.6 to 23 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.
Sand, clay. Age: Miocene to Pliocene, 2.6 to 23 million years old. About 14 mi of the line.
Sand. Age: Late Pliocene, 2.6 to 3.6 million years old. About 9 mi of the line.
Sand. Age: Holocene, less than 12,000 years old. About 0.9 mi of the line.
Clay. Age: Eocene to Miocene, 5.3 to 56 million years old. About 0.6 mi of the line.

A raindrop that lands in Lockhart reaches Pensacola Bay and the Gulf of America by way of Pond Creek, the Shoal and the Yellow: about 80 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lockhart; river miles along the main stem, rounded.
Lockhart has a humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 38° in January. About 64 inches of rain fall in a normal year.
