1953 Map of Eastern Isles Dernieres

About this map

Isles Dernieres barrier islands define the southern boundary of this coastal survey, shielding the interior marshlands from the Gulf of Mexico. The landscape is a complex of shifting sands and tidal channels, where Trinity Bayou and Trinity Bay intersect with the open waters of Lake Pelto. By the mid-20th century, industrial activity becomes evident with the development of the Lake Pelto Oil Field, marked by a Radio Mast and specific infrastructure near Point Mast. This period shows the transition from a purely natural barrier system to an actively utilized resource zone. Navigational points such as Bodwin Point and tidal inlets like Wine Island Pass provide critical orientation for maritime history in Terrebonne Parish, while features like Old Camp Pass hint at seasonal or temporary human presence among the dunes.
