Archeologists working on an island just off Miami believe they’ve found a unique stone Indian burial mound. But with part of the site underwater, the team is battling a rising sea that threatens to cover the East Coast’s low-lying areas within the century.

It’s not easy to get to the dig site.

First, a 40-minute ride in a National Park Service boat ironically nicknamed Speedy.

Then, just off Totten Key, archeologist Josh Marano navigates the boat through a manmade channel cut from rocks that have shipwrecked lesser captains.
