About this map

Nanahubba Bluff and Seaboard Bluff overlook the convergence of Alabama's great river systems in this 2018 survey. The landscape is dominated by the intricate hydrology where the Tombigbee River and Alabama River meet to form the Mobile River. This fluvial environment is characterized by numerous secondary waterways and named backwaters such as Tuggin Slough, Joe Bayou, and the Alabama River Cutoff, illustrating the shifting nature of these wetlands.

Upland from the river bottoms, the map reveals human imprints including Big John Cem and a network of rural roads such as Bates Lake Rd and Griffin Rd. The survey details the complex boundary intersections of Mobile, Baldwin, Washington, and Clarke Counties, which all converge within this watery labyrinth. Topographic features like Bilbo Island and Calverts Bar highlight the sediment-rich environment of the delta's upper reaches.
