About this map

Crescent City sits at the northern edge of this coastal survey, where the maritime infrastructure of the Lighthouse at Battery Point and the industrial activity of Citizens Dock meet the Pacific. The coastline south of the city reveals a landscape of sea stacks and treacherous underwater hazards, including Whaler Island, Pelican Rock, and the submerged Chase Ledge. Hydrographic data compiled from 1920s surveys and 1960s charts Detail the depth curves and tidal flats that defined navigation during this era.
