McLeod’s center stands about 320 ft above sea level. Within three miles the land runs from 220 ft to 370 ft, a difference of 150 ft: gently rolling country.
Under the town center the state geologic map shows Queen City Sand (siltstone, sandstone), from the Middle Eocene, 38 to 48 million years old.
The section below crosses 8 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.
Siltstone, sandstone. Age: Middle Eocene, 38 to 48 million years old. About 13 mi of the line.
Clay. 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 2 mi of the line.
Sand, clay, lignite. Age: Paleocene, 56 to 66 million years old. About 2 mi of the line.
Sandstone. Age: Middle Eocene, 38 to 48 million years old. About 1 mi of the line.
Clay, silt. Age: Eocene, 34 to 56 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. 2 smaller units along the line are not listed.
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 McLeod reaches the Gulf of America by way of Clear Creek, Black Bayou, Twelvemile Bayou, Cross Bayou, the Red River, the Atchafalaya and the Lower Atchafalaya: about 450 river miles.
Lake on the way: Black Bayou Lake.
260 miles of the trip are on the Red River.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of McLeod; river miles along the main stem, rounded.
