Filley’s center stands about 1,420 ft above sea level. Within three miles the land runs from 1,350 ft to 1,510 ft, a difference of 160 ft: gently rolling country.
Under the town center the state geologic map shows Chase Group (limestone, shale), from the Permian, 252 to 299 million years old.
The section below crosses 3 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.
Limestone, shale. Age: Permian, 252 to 299 million years old. About 11 mi of the line.
Shale, limestone. Age: Permian, 252 to 299 million years old. About 9 mi of the line.
Shale, limestone. Age: Permian, 252 to 299 million years old. About 4 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 Filley reaches the Gulf of America by way of Mud Creek, the Big Blue, the Kansas, the Missouri and the Mississippi: about 1,810 river miles.
Lake on the way: Tuttle Creek Lake.
1,170 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Filley; river miles along the main stem, rounded.
