About this map

Bayou Grand Caillou serves as the central artery for this coastal Louisiana landscape, where settlement patterns strictly follow the narrow natural levees between the marshes. Small community hubs like Dulac, Boudreaux, and Theriot are tightly clustered along the waterways, connected by a network that includes the massive Houma Navigation Canal and a ferry crossing. The map reveals a high density of family-named cemeteries such as Celestin Cem and Provost Cem, which are vital markers for genealogical research in this subsidence-prone region.

Industrial activity is evidenced by the South Houma Oil and Gas Field and numerous oil wells dotting the wetlands east of the main bayou. Large expanses of open water and marsh, including Lake Boudreaux and Lake Gero, dominate the eastern half of the sheet, while named drainage features like Forty Acre Bayou and Bayou Guillaume illustrate the complex hydrology of Terrebonne Parish in the early 1960s.
