New Braunfels’s center stands about 640 ft above sea level. Within three miles the land runs from 600 ft to 900 ft, a difference of 300 ft: rolling country. The highest named summit within 15 miles is Startz Hill, about 1,410 ft, 13 miles northwest.
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 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 26×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Coarse-detrital, fine-detrital. Age: Pleistocene, less than 2.6 million years old. About 10 mi of the line.
Limestone. Age: Early Cretaceous, 100 to 113 million years old. About 9 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 3 mi of the line.
Limestone. Age: Late Cretaceous, 66 to 100 million years old. About 1 mi of the line.
Marlstone, chalk. Age: Late Cretaceous, 66 to 100 million years old. About 0.5 mi of the line.
Limestone, marlstone. Age: Early Cretaceous, 100 to 145 million years old. About 0.3 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
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 New Braunfels reaches the Gulf of America by way of the Guadalupe and the South Guadalupe: about 280 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of New Braunfels; river miles along the main stem, rounded.
New Braunfels has a humid subtropical climate. Summer afternoons average 97° in August; winter nights fall to about 40° in January. About 31 inches of rain fall in a normal year.
Normals 1991–2020 and records since 1996 at New Braunfels Municipal Airport, 5 miles east. NOAA, through RCC-ACIS.
