Beggs’s center stands about 730 ft above sea level. Within three miles the land runs from 680 ft to 890 ft, a difference of 210 ft: rolling country. The highest named summit within 15 miles is Dude Ranch Hill, about 1,050 ft, 6 miles east-northeast.
Under the town center the state geologic map shows Holdenville Formation or Holdenville Shale (shale, sandstone, conglomerate), from the Carboniferous, 299 to 324 million years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 50×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 11 mi of the line.
Shale, sandstone, limestone. Age: Carboniferous, 299 to 324 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.
Shale, sandstone, conglomerate. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Shale, sandstone, conglomerate. Age: Carboniferous, 299 to 324 million years old. About 1 mi of the line.
Shale, limestone, sandstone. Age: Carboniferous, 299 to 324 million years old. About 0.7 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit 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 Beggs reaches the Gulf of America by way of Adams Creek, the Deep Fork, the North Canadian, the Canadian, the Arkansas and the Mississippi: about 1,090 river miles.
Lakes on the way: Murray Lake and Ozark Lake.
600 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Beggs; river miles along the main stem, rounded.
