Tilden’s center stands about 250 ft above sea level. Within three miles the land runs from 230 ft to 380 ft, a difference of 150 ft: gently rolling country. The highest named summit within 15 miles is Kings Hills, about 480 ft, 6 miles south-southwest.
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 6 mi of the line.
Clay, sand. Age: Late Eocene to Early Oligocene, 28 to 38 million years old. About 5 mi of the line.
Claystone. Age: Late Eocene, 34 to 38 million years old. About 4 mi of the line.
Claystone, sandstone. Age: Eocene, 34 to 56 million years old. About 4 mi of the line.
Clay. Age: Oligocene, 23 to 34 million years old. About 3 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 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.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Tilden reaches Corpus Christi Bay and the Gulf of America by way of the Frio and the Nueces: about 130 river miles.
Lakes on the way: Horseshoe Tank and Lake Corpus Christi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Tilden; river miles along the main stem, rounded.
Tilden has a humid subtropical climate. Summer afternoons average 97° in August; winter nights fall to about 43° in January. About 26 inches of rain fall in a normal year.
On November 14 Tilden normally reaches 74° and falls to 52°. The record high is 93°, in 1993; the record low 29°, in 2018. The most rain on this date, 1.48 in, fell in 1998.
Normals 1991–2020 and records since 1983 at Choke Canyon Dam, 18 miles east. NOAA, through RCC-ACIS.
