The Monticello plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
Monticello’s center stands about 200 ft above sea level. Within three miles the land runs from 160 ft to 390 ft, a difference of 230 ft: rolling country. The highest named summit within 15 miles is Hope Hill, about 480 ft, 15 miles south-southwest.
Under the town center the state geologic map shows Pascagoula and Hattiesburg formation (clay, sand), from the Miocene, 5.3 to 23 million years old.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 57×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Clay, sand. Age: Miocene, 5.3 to 23 million years old. About 15 mi of the line.
Sand, gravel. Age: Pliocene to Pleistocene, less than 5.3 million years old. About 9 mi of the line.

A raindrop that lands in Monticello reaches the Gulf of America by way of the Pearl: about 200 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Monticello; river miles along the main stem, rounded.
