Monticello’s center stands about 680 ft above sea level. Within three miles the land runs from 510 ft to 720 ft, a difference of 210 ft: rolling country.
Under the town center the state geologic map shows Hornblende Gneiss/ Amphibolite (hornblende-gneiss, amphibolite), from the Precambrian to Paleozoic.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 58×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Hornblende-gneiss, amphibolite. Age: Precambrian to Paleozoic. About 17 mi of the line.
Gneiss, amphibolite. Age: Precambrian to Paleozoic. About 6 mi of the line.
Gneiss, mica-schist, amphibolite. Age: Precambrian to Paleozoic. About 1 mi of the line.
Hornfels. Age: Precambrian to Paleozoic. About 0.5 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 Monticello reaches the Atlantic Ocean by way of White Oak Creek, Murder Creek, the Little River, the Oconee and the Altamaha: about 310 river miles.
140 miles of the trip are on the Oconee.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Monticello; river miles along the main stem, rounded.
