3.41 inches of rain fell in two days, the most for this week of the year since records began in 1882. The next wettest, 3.40 inches, fell in 1998.
Hearne’s center stands about 300 ft above sea level. Within three miles the land runs from 250 ft to 430 ft, a difference of 180 ft: gently rolling country. The highest named summit within 15 miles is Wilson Hill, about 530 ft, 15 miles west-southwest.
Under the town center the state geologic map shows Terrace deposits (sand), from the Pleistocene to Holocene, less than 2.6 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 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.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 7 mi of the line.
Sandstone. Age: Eocene, 34 to 56 million years old. About 7 mi of the line.
Siltstone, sandstone. Age: Middle Eocene, 38 to 48 million years old. About 4 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 3 mi of the line.
Sandstone. Age: Eocene, 34 to 56 million years old. About 2 mi of the line.
Claystone. Age: Late Paleocene to Early Eocene, 48 to 59 million years old. About 1 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 Hearne reaches the Gulf of America by way of Lost Creek and the Brazos: about 320 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Hearne; river miles along the main stem, rounded.
Hearne has a humid subtropical climate. Summer afternoons average 97° in August; winter nights fall to about 41° in January. About 42 inches of rain fall in a normal year.
On November 14 Hearne normally reaches 71° and falls to 50°. The record high is 94°, in 1921; the record low 27°, in 1940. The most rain on this date, 1.64 in, fell in 1998.
Normals 1991–2020 and records since 1882 from the College Station Area threaded record (College Station Easterwood Field, 24 miles southeast). NOAA, through RCC-ACIS.
