 The students now are excavating these what we call shell middens, which are really trash accumulations that date to around 500 B.C., 100 A.D. So we've been out here the last six weeks really excavating. So students are now kind of learning the proper techniques to do archeological excavation. A lot of this area had been mined commercially for shell in the 30s and 40s and early 50s. So there's major damage to these shell mounds. Some of the area had been damaged by uprooted trees due to hurricanes Irma and Matthew. So we're just checking to see what damage has been done, what part is intact. It's really looking at their daily existence. So we're finding what they're eating and they're eating a lot of fish. We're getting redfish. We're getting sea trout. We're getting black drum. We're getting catfish, mullet flounder. So we're getting a lot of the species that people catch today. We're getting crab, blue crab. And then we're also getting lots and lots of oyster shell. So they're eating really well from the marsh. Then we're getting pottery so we can get an idea of their technology. We've gotten a few bone and shell artifacts as well. So really it's just their daily existence.
