Proctor’s center stands about 1,210 ft above sea level. Within three miles the land runs from 1,130 ft to 1,410 ft, a difference of 280 ft: rolling country. The highest named summit within 15 miles is Sand Mountain, about 1,460 ft, 5 miles east-southeast.
Under the town center the state geologic map shows Twin Mountains Formation (claystone, sandstone), from the Early Cretaceous, 100 to 145 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 45×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Claystone, sandstone. Age: Early Cretaceous, 100 to 145 million years old. About 12 mi of the line.
Limestone, shale. Age: Early Cretaceous, 100 to 145 million years old. About 4 mi of the line.
Limestone, marlstone. Age: Early Cretaceous, 100 to 145 million years old. About 4 mi of the line.
Sandstone. Age: Early Cretaceous, 100 to 145 million years old. About 2 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 2 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 Proctor reaches the Gulf of America by way of Walnut Creek, the Leon, the Little River and the Brazos: about 640 river miles.
Lake on the way: Belton Lake.
320 miles of the trip are on the Brazos.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Proctor; river miles along the main stem, rounded.
