Hickory’s center stands about 1,240 ft above sea level. Within three miles the land runs from 1,160 ft to 1,300 ft, a difference of 140 ft: gently rolling country.
Under the town center the state geologic map shows Bromide + Tulip Creek and McLish Formations (limestone, shale, sandstone), from the Middle Ordovician, 459 to 471 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 48×. 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, dolostone. Age: Early Ordovician, 471 to 487 million years old. About 7 mi of the line.
Limestone, shale, sandstone. Age: Middle Ordovician, 459 to 471 million years old. About 4 mi of the line.
Shale, sandstone, limestone. Age: Carboniferous, 299 to 324 million years old. About 4 mi of the line.
Coarse-detrital, fine-detrital. Age: Pleistocene, less than 2.6 million years old. About 3 mi of the line.
Limestone, shale. Age: Middle Ordovician to Late Ordovician, 445 to 471 million years old. About 2 mi of the line.
Limestone, shale, sandstone. Age: Middle Ordovician, 459 to 471 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.

A raindrop that lands in Hickory reaches the Gulf of America by way of Mill Creek, the Washita, the Red River, the Atchafalaya and the Lower Atchafalaya: about 900 river miles.
680 miles of the trip are on the Red River.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Hickory; river miles along the main stem, rounded.
