The Crescent City 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.
Crescent City’s center stands about 60 ft above sea level. Within three miles the land runs from 0 ft to 120 ft, a difference of 120 ft: gently rolling country. Open water lies within three miles.
Under the town center the state geologic map shows Cypresshead Formation (sand), from the Late Pliocene, 2.6 to 3.6 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.
Sand, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 11 mi of the line.
Sand. Age: Late Pliocene, 2.6 to 3.6 million years old. About 5 mi of the line.
Sand. Age: Holocene, less than 12,000 years old. About 0.3 mi of the line.

A raindrop that lands in Crescent City reaches the St. Johns River and the Atlantic Ocean by way of Crescent Lake and Dunns Creek: about 110 river miles.
Lake on the way: Crescent Lake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Crescent City; river miles along the main stem, rounded.
