1953 Map of Cat Island Pass

USGS Topo · Published 1981

About this map

Timbalier Island and the neighboring Wine Island anchor this coastal survey, where the waters of Terrebonne Bay meet the open Gulf of Mexico. The landscape is defined by the shifting shoals and deep-water channels of Cat Island Pass, a critical maritime artery in Louisiana's coastal marshlands. This edition, photorevised in the late 1970s, reveals the industrial footprint of the offshore energy sector with the Caillou Island Field and multiple installations marked simply as Oil Well. Navigational aids like the Light and Marker No 1 emphasize the importance of safe passage through these treacherous barrier island gaps, where the shoreline is subject to constant change from tide and storm surge.
