Marlow’s center stands about 1,310 ft above sea level. Within three miles the land runs from 1,180 ft to 1,400 ft, a difference of 220 ft: rolling country.
Under the town center the state geologic map shows Rush Springs Formation (sandstone), from the Permian, 252 to 299 million years old.
The section below crosses 9 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 53×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Coarse-detrital, fine-detrital. Age: Pleistocene, less than 2.6 million years old. About 9 mi of the line.
Sandstone, conglomerate. Age: Permian, 252 to 299 million years old. About 4 mi of the line.
Fine-detrital. Age: Holocene, less than 12,000 years old. About 3 mi of the line.
Sandstone, siltstone. Age: Permian, 252 to 299 million years old. About 3 mi of the line.
Sandstone. Age: Permian, 252 to 299 million years old. About 2 mi of the line.
Conglomerate, shale, siltstone. Age: Permian, 252 to 299 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. 3 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 Marlow reaches the Gulf of America by way of Hell Creek, Little Beaver Creek, Beaver Creek, the Red River, the Atchafalaya and the Lower Atchafalaya: about 1,050 river miles.
840 miles of the trip are on the Red River.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Marlow; river miles along the main stem, rounded.
