About this map

Grand Chenier Ridge and its surrounding coastal wetlands define this corner of Cameron Parish, where land and water merge into a complex network of bayous and marshes. The settlement of Grand Chenier sits along the southern edge of the survey, oriented by the winding Mermentau River and the industrial infrastructure of the Mermentau River Navigational Channel. The geography is characterized by distinct cheniers—sandy ridges often supporting live oak groves—such as Little Chenier Ridge, Chenier Perdue Ridge, and Hackberry Ridge, which provided critical high ground for early settlers and agriculture.

Water dominates the landscape through large features like Upper Mud Lake and Little Pecan Lake, while smaller arteries like Marseillaise Bayou and Pumpkin Bayou drain the interior. Local family and place names are preserved in the road network, including Carl McCall Rd, Bonsall Rd, and Indian Point Rd, the latter leading to Indian Point Island. The map records a modern state of the Gulf Coast's drainage and settlement patterns.
