Ft Pike stands at the strategic nexus where The Rigolets connects Lake Pontchartrain and Lake Borgne. This deep-water pass serves as a primary maritime artery between St Tammany Parish and Orleans Parish, shaped by an intricate network of tidal channels including Salt Bayou and Perdido Bayou. The landscape is dominated by marshlands and ridges like Apple Pie Ridge, while navigation is aided by the W Rigolets LH lighthouse. The Louisville and Nashville RR cuts through the wetlands, paralleling Highway No 90 to bridge the gap between the isolated settlement of Rigolets and the surrounding coastal islands. Notable landforms such as Prevost Island, Hog Island, and Rabbit Island illustrate the fragmented geography of the Louisiana coast during the mid-20th century, before major modern coastal erosion altered these tidewater passes.
