20° on Nov. 12, 2019, the coldest reading for this week of the year since 1940. Next is 22° in 2014.
Rosser’s center stands about 360 ft above sea level. Within three miles the land runs from 320 ft to 400 ft, a difference of 80 ft: gently rolling country.
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 5 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.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 11 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 6 mi of the line.
Claystone. Age: Late Cretaceous, 66 to 72 million years old. About 4 mi of the line.
Sandstone-mudstone. Age: Late Cretaceous, 66 to 72 million years old. About 2 mi of the line.
Sandstone. Age: Late Cretaceous, 66 to 72 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.
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 Rosser reaches Galveston Bay and the Gulf of America by way of the Trinity: about 410 river miles.
Lake on the way: Woodlands Golf Course Lake.
220 miles of the trip are on the Trinity.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Rosser; river miles along the main stem, rounded.
Rosser has a humid subtropical climate. Summer afternoons average 97° in August; winter nights fall to about 36° in January. About 41 inches of rain fall in a normal year.
On November 14 Rosser normally reaches 68° and falls to 45°. The record high is 89°, in 1989; the record low 25°, in 2018. The most rain on this date, 1.32 in, fell in 1994.
Normals 1991–2020 and records since 1940 at Ferris, 13 miles west-northwest, 110 ft higher. NOAA, through RCC-ACIS.
