Patriots Point is a well-known landmark on the east bank of the Cooper River in the Town of Mount Pleasant, but its modern name obscures a much deeper history. Known as Hog Island before 1973, the site has been radically transformed by nature and humans over the past three centuries. Its evolution from a tiny but habitable island to an expansive, vacant marshland, to a thriving community atop a mountain of dredge spoil, illustrates the shifting dynamics of tidal forces and human engineering that have reshaped the local ecology.
