The Shelter Cove 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.
Shelter Cove’s center stands about 150 ft above sea level. Within three miles the land runs from 10 ft to 2,330 ft, a difference of 2,320 ft: mountain country. Open water lies within three miles. The highest named summit within 15 miles is King Peak, about 4,040 ft, 9 miles north-northwest.
Under the town center the state geologic map shows Franciscan Complex, unit 1 (Coast Ranges) (sandstone, mudstone), from the Jurassic to Cretaceous, 66 to 202 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 5×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone, mudstone. Age: Late Cretaceous to Pliocene, 2.6 to 100 million years old. About 6 mi of the line.
Sandstone, mudstone. Age: Jurassic to Cretaceous, 66 to 202 million years old. About 2 mi of the line.

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 Shelter Cove reaches the Pacific Ocean by way of Telegraph Creek: about 1 river miles.
