3.91 inches of rain fell in two days, the most for this week of the year since records began in 1937. The next wettest, 2.94 inches, fell in 1987.
Marquez’s center stands about 410 ft above sea level. Within three miles the land runs from 330 ft to 450 ft, a difference of 120 ft: gently rolling country.
Under the town center the state geologic map shows Reklaw Formation (sandstone), from the Eocene, 34 to 56 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 59×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Siltstone, sandstone. Age: Middle Eocene, 38 to 48 million years old. About 11 mi of the line.
Sandstone. Age: Eocene, 34 to 56 million years old. About 5 mi of the line.
Sandstone. Age: Eocene, 34 to 56 million years old. About 3 mi of the line.
Claystone. Age: Late Paleocene to Early Eocene, 48 to 59 million years old. About 3 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 2 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.5 mi of the line.

A raindrop that lands in Marquez reaches the Gulf of America by way of Sour Branch, the Navasota and the Brazos: about 340 river miles.
230 miles of the trip are on the Brazos.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Marquez; river miles along the main stem, rounded.
Marquez has a humid subtropical climate. Summer afternoons average 95° in August; winter nights fall to about 35° in January. About 42 inches of rain fall in a normal year.
On November 14 Marquez normally reaches 70° and falls to 44°. The record high is 88°, in 1955; the record low 21°, in 2019. The most rain on this date, 0.45 in, fell in 1993.
Normals 1991–2020 and records since 1937 at Centerville, 17 miles east. NOAA, through RCC-ACIS.
