Little is known about the six mounds found at the parkâs border with Crabbe Elementary, according to archaeologist Matthew Davidson. Davidson and archaeologist Jason Flay, are organizing a survey near the mounds with archaeologists across the state this weekend to start answering questions that have plagued researchers for nearly a hundred years. According to Davidson, who studied mounds found throughout Boyd, Greenup, Carter, Lewis and Lawrence when he was working towards his PhD, said the last crack at researchers attempted to find answers on the mounds was in the 1930s by the University of Kentucky.
