The Harvey Cedars 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.
Harvey Cedars’s center stands barely above sea level. Within three miles the land runs from 0 ft to 20 ft, a difference of 20 ft: nearly flat ground. Open water lies within three miles. The highest named summit within 15 miles is Forked River Mountain, about 190 ft, 13 miles northwest.
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 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. Age: Middle Miocene, 12 to 14 million years old. About 8 mi of the line.
Clay, sand. Age: Early Miocene to Middle Miocene, 14 to 20 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
