St. Joseph Bay is a large body of water enclosed by St. Joseph Peninsula. The St. Joseph Peninsula is 17 miles long and has an average width of 1,000 feet. It is formed from the Cape San Blas shoals and the historical migration of the Apalachicola River. The cape and the spit sediments are quartz sands originally supplied by the Apalachicola River. Waves and other shore zone processes have put the beaches in a constant state of change over the last hundred years.
