2015 Map of Cannibal Island

About this map

The delta of the Eel River and its intricate network of coastal waterways define this coastal region of Humboldt County. Low-lying landforms such as Cannibal Island, Mosley Island, and Cock Robin Island are separated by a complex system of sloughs, including Sevenmile Slough, McNulty Slough, and Hawk Slough. This landscape is primarily shaped by the intersection of freshwater drainage and the tidal influence of the Pacific Ocean, which meets the shore along the narrow South Spit. In the eastern section, Loleta Bottoms represents the agricultural character of the river valley, while the rise of Table Bluff provides a distinct change in elevation above the marshy lowlands. Local transport is reflected in family and place-named routes like Copenhagen Rd, Cannibal Island Rd, and Quinn Rd, tracing the early settlement patterns of this tidal basin.
