Inter-locking palmetto logs were used to construct a crib which was weighted down and sunk in the river. The logs are attached by means of long wooden guide posts visible at the bottom of the cribbing structure. In addition to the cribbing forming the sides of the rectangle on the Mepkin dock, a layer of cribbing was added to the middle of the rectangle dividing it into two compartments. This provided extra stability and strength for the structure. Interlocking Cribbing of the Dock Structure Diving Advice Underwater slates with the maps and history of each site will be sold through interested dive stores.
Divers have the option of diving through a local dive store or charter business, or as individuals.
It is recommended that they at least purchase the underwater maps. The best time to dive on these sites is during the incoming tide which counteracts the natural outflow of the river thereby lessening the strength of the current. Consult local tide tables for times of tides. Generally, tides in the trail area run about three and a half hours behind the listed times for Charleston harbor. Divers should descend down the mooring line to the monument which is equipped with signage that identifies the dive site and sponsors.
