The Fenwick 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.
Fenwick’s center stands about 20 ft above sea level. Within three miles the land runs from 0 ft to 130 ft, a difference of 130 ft: gently rolling country. Open water lies within three miles. The highest named summit within 15 miles is Tater Hill, about 650 ft, 13 miles north.
Under the town center the state geologic map shows Unknown - Unmapped.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 42×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
