1. Coastal Heritage Under Threat Marker
In front of you once stood Spanish Mount, a massive 20-foot shell mound Native People created nearly 4,000 years ago. Spanish Mount was one of many large shell monuments constructed in the Low Country around this time. Today storms, flooding, rising seas, and coastal development are erasing these features from the land. Spanish Mount has not been spared. By 2016, the mound measured just three feet high.
Before it eroded completely, archaeologists carefully excavated and documented the shell deposits. Layer by layer, they recorded different shell concentrations and recovered artifacts left by the people who were here.
Native People deposited oyster, whelk, crab, clam, periwinkle, fish, turtle, rabbit, deer, and pottery - leftovers from their meals - in a way that looks purposeful. Can you see the slope of shell deposits that formed the once-rounded mound?
Archaeologists are studying artifacts left behind to learn about the daily lives of the Native People who created this monument.
