Denton’s center stands about 80 ft above sea level. Within three miles the land runs from 0 ft to 120 ft, a difference of 120 ft: gently rolling country.
Under the town center the state geologic map shows Upland Deposits (Eastern Shore) (gravel, sand), from the Pleistocene, less than 2.6 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 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.
Fine-detrital, coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 7 mi of the line.
Gravel, sand. Age: Pleistocene, less than 2.6 million years old. About 7 mi of the line.
Silt. Age: Tertiary, 2.6 to 66 million years old. About 5 mi of the line.
Sand, silt. Age: Miocene, 5.3 to 23 million years old. About 2 mi of the line.
Sand, clay. Age: Miocene, 5.3 to 23 million years old. About 0.4 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 Denton reaches Chesapeake Bay and the Atlantic Ocean by way of the Choptank: about 45 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Denton; river miles along the main stem, rounded.
