24° on Nov. 15, 1908, the coldest reading for this week of the year since 1902. Next is 29° in 1920.
Las Haciendas’s center stands about 630 ft above sea level. Within three miles the land runs from 540 ft to 660 ft, a difference of 120 ft: gently rolling country.
Under the town center the state geologic map shows Jackson Group, undivided (clay), from the Late Eocene to Early Oligocene, 28 to 38 million years old.
The section below crosses 3 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.
Clay. Age: Late Eocene to Early Oligocene, 28 to 38 million years old. About 12 mi of the line.
Claystone, sandstone. Age: Eocene, 34 to 56 million years old. About 7 mi of the line.
Sandstone, claystone. Age: Eocene, 34 to 56 million years old. About 4 mi of the line.

A raindrop that lands in Las Haciendas reaches Corpus Christi Bay and the Gulf of America by way of Becerra Creek, San Casimiro Creek and the Nueces: about 220 river miles.
Lake on the way: Lake Corpus Christi.
100 miles of the trip are on the Nueces.
Often dry. About 30% of the way is mapped as streams that run only after rain or snowmelt; the water makes the whole trip in floods.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Las Haciendas; river miles along the main stem, rounded.
Las Haciendas has a hot semi-arid climate. Summer afternoons average 101° in August; winter nights fall to about 47° in January. About 21 inches of rain fall in a normal year.
On November 14 Las Haciendas normally reaches 77° and falls to 56°. The record high is 96°, in 1903; the record low 28°, in 1908. The most rain on this date, 0.46 in, fell in 1920.
