Scores of Native American mounds have been lost through time, but the one thought to be the nation's highest -- Canaveral National Seashore's Turtle Mound -- survived.
Preservation of the mound has saved many of its secrets, clues to the past never unearthed.
That's why archaeologists and park rangers are excited to learn as much as they can from new holes dug into the massive oyster-shell pile last week.
Pretty good article and it's got a video, too. What was with the post-hole diggers?
