2016 Map of Pass Cavallo SW

About this map

Matagorda Island stretches across this coastal survey, serving as a narrow barrier between the open Gulf of Mexico and the sheltered waters of the Texas mainland. This environment is defined by the complex movement of sand and sea at the intersection of Espiritu Santo Bay and Matagorda Bay. The map documents the critical waterway of Pass Cavallo, a natural opening that has historically dictated maritime access to the inner bays.
