Salt River Bay

Salt River Bay

The submarine canyon at the mouth of Salt River Bay provides habitat for deep water corals, sponges and fishes. The site is primarily located within the Salt River Bay National Historical Park and Ecological Preserve and also includes Sugar Bay, the shores of which support the best remaining stands of mangrove in the Virgin Islands. These undisturbed stands illustrate the zonation of red, black, and white mangrove and support a multitude of bird species. Overall, the Salt River Estuary is an excellent example of mixed carbonate and clastic sedimentation processes.
