They had found not only the datum marker from the 1992 season, but a barnacle-covered stone projectile point. This is a mid-Archaic stemmed point. It is similar in form and fabrication to a point type known as Newnans Lake, which is about 6,000 years old. On a subsequent dive, Bobby Francis descents to lay out a transect line with a tape measure. Then he can swim along this line, collecting artifacts on the sea floor and hand fanning the sediments away at regular intervals to help discern the locations and patterning of artifacts under the sediments.
Dolphins visit the divers regularly during the working dives.
More annoying visitors include schools of remora, like this one in the image below. These fish mistake the archaeologists for sharks and try to attach themselves to working divers. While harmless, this can certainly be distracting, as these fish are persistent. This is one of the test units, Test Unit 2, excavated by divers with the suction dredge. The hole can be seen in the foreground, and separate layers of sediments can be seen in the wall of the unit.
