This natural pass, one of the only three in Texas, was used by Mexican merchants, smugglers and pirates as a highway from the sea. With each big storm, the pass would shift and choke with sandbars, making it the scene of many shipwrecks. In an attempt to tame it, the Army Corps of Engineers tried four times over 60 years to build jetties that would capture the channel. The existing jetties were completed in the 1930’s. Millions of tons of shipping vessels and thousands of pleasure and sport ﬁshing boats use it as a pathway to the Gulf of Mexico annually.
