The Uhland 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.
5.75 inches of rain fell in two days, the most for this week of the year since records began in 1893. The next wettest, 3.12 inches, fell in 2001.
Uhland’s center stands about 550 ft above sea level. Within three miles the land runs from 510 ft to 690 ft, a difference of 180 ft: gently rolling country. The highest named summit within 15 miles is Carpenter Hills, about 890 ft, 11 miles northwest.
Under the town center the state geologic map shows Alluvium (fine-detrital, coarse-detrital), from the Holocene, less than 12,000 years old.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 37×. 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 5 mi of the line.
Clay, siltstone-mudstone. Age: Late Cretaceous, 66 to 100 million years old. About 4 mi of the line.
Limestone, carbonate. Age: Late Cretaceous, 66 to 72 million years old. About 4 mi of the line.
Limestone. Age: Early Cretaceous, 100 to 113 million years old. About 3 mi of the line.
Marlstone, chalk. Age: Late Cretaceous, 66 to 100 million years old. About 3 mi of the line.
Mudstone. Age: Late Paleocene to Early Eocene, 48 to 59 million years old. About 3 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 smaller units 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 Uhland reaches the Gulf of America by way of Plum Creek, the San Marcos, the Guadalupe and the South Guadalupe: about 240 river miles.
180 miles of the trip are on the Guadalupe.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Uhland; river miles along the main stem, rounded.
Uhland has a humid subtropical climate. Summer afternoons average 97° in August; winter nights fall to about 39° in January. About 37 inches of rain fall in a normal year.
On November 14 Uhland normally reaches 72° and falls to 49°. The record high is 89°, in 1951; the record low 24°, in 2018. The most rain on this date, 2.03 in, fell in 1959.
