One of the greatest concentrations of wildlife in the world occurs on San Miguel. If you look carefully at this photo you may see as many as thirty thousand seals and sea lions hauled-out on the isolated, sandy beaches around Point Bennet.
Foul weather and submerged rock and shoals have led to a large number of shipwrecks around San Miguel, such as the EX Tortuga in 1987 near Cardwell Point. The ship was eventually towed out to sea and sunk.
San Miguel’s 600 archeological sites reveal occupation by American Indians back to 10,700 years before the present. The 1995 discovery of sea grass basketry and cordage fragments are the oldest to date on the Pacific coast.
