Hosston’s center stands about 200 ft above sea level. Within three miles the land runs from 170 ft to 340 ft, a difference of 170 ft: gently rolling country. The highest named summit within 15 miles is Delaney Mount, about 480 ft, 8 miles east-northeast.
Under the town center the state geologic map shows Cane River Formation (clay, silt), from the Eocene, 34 to 56 million years old.
The section below crosses 10 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.
Silt, clay. Age: Holocene, less than 12,000 years old. About 6 mi of the line.
Clay, silt, sand. Age: Pleistocene, less than 2.6 million years old. About 5 mi of the line.
Clay, marl. Age: Eocene, 34 to 56 million years old. About 4 mi of the line.
Sand, clay, lignite. Age: Paleocene, 56 to 66 million years old. About 4 mi of the line.
Clay. Age: Holocene, less than 12,000 years old. About 2 mi of the line.
Sandstone. Age: Eocene, 34 to 56 million years old. About 0.9 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 4 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 Hosston reaches the Gulf of America by way of Black Bayou, Twelvemile Bayou, Cross Bayou, the Red River, the Atchafalaya and the Lower Atchafalaya: about 440 river miles.
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 Hosston; river miles along the main stem, rounded.
