8.32 inches of rain fell in two days, the most for this week of the year since records began in 1903. The next wettest, 4.59 inches, fell in 1985.
Point Blank’s center stands about 230 ft above sea level. Within three miles the land runs from 130 ft to 320 ft, a difference of 190 ft: gently rolling country.
Under the town center the state geologic map shows Fleming Formation (clay, sandstone), from the Miocene, 5.3 to 23 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 58×. 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, sandstone. Age: Miocene, 5.3 to 23 million years old. About 8 mi of the line.
Coarse-detrital, fine-detrital. Age: Pliocene, 2.6 to 5.3 million years old. About 7 mi of the line.
Sand. Age: Pleistocene, less than 2.6 million years old. About 0.7 mi of the line.
Silt, sand, clay. Age: Pleistocene, less than 2.6 million years old. About 0.5 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 0.5 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 Point Blank reaches Galveston Bay and the Gulf of America by way of Mill Creek and the Trinity: about 140 river miles.
Lake on the way: Woodlands Golf Course Lake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Point Blank; river miles along the main stem, rounded.
Point Blank has a humid subtropical climate. Summer afternoons average 93° in August; winter nights fall to about 39° in January. About 51 inches of rain fall in a normal year.
On November 14 Point Blank normally reaches 68° and falls to 48°. The record high is 89°, in 1959; the record low 25°, in 2019. The most rain on this date, 1.52 in, fell in 1998.
