1980 Map of Carancahua Pass

USGS Topo · Published 1981

About this map

Matagorda Bay dominates this coastal survey, where the Calhoun Co Matagorda Co line bisects the open water. The map documents the intricate maritime infrastructure of the early 1980s, tracing the deep-water Palacios Channel as it cuts across the bay floor toward the north. Navigational aids, labeled simply as Light and Daybeacon, mark the essential paths for Gulf vessels navigating the transition from the Intracoastal Waterway through Carancahua Pass. To the southeast, the submerged topography of Halfmoon Reef provides a notable landmark for those studying the shifting shoreline and oyster reef formations of the Texas coast. This edition reflects hydrographic data compiled just after the late 1970s, offering a precise view of the seafloor before modern coastal changes.
