Malakoff’s center stands about 380 ft above sea level. Within three miles the land runs from 280 ft to 430 ft, a difference of 150 ft: gently rolling country. The highest named summit within 15 miles is Big Rock Top, about 660 ft, 14 miles north-northeast.
Under the town center the state geologic map shows Wilcox Group, undivided (mudstone), from the Late Paleocene to Early Eocene, 48 to 59 million years old.
The section below crosses 4 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.
Mudstone. Age: Late Paleocene to Early Eocene, 48 to 59 million years old. About 13 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 7 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 3 mi of the line.
Sandstone. Age: Eocene, 34 to 56 million years old. About 0.4 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 Malakoff reaches Galveston Bay and the Gulf of America by way of Cedar Creek and the Trinity: about 340 river miles.
Lake on the way: Woodlands Golf Course Lake.
150 miles of the trip are on the Trinity.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Malakoff; river miles along the main stem, rounded.
