Archaeologists reveal research that uncovers clues to fate of vanished civilizations in the Grand Canyon
Archaeologists Ellen Brennen crouched in the relentless sun, meticulously uncovering the curious, two-chambered hearth in the floor of a sunken, circular room built 1,000 years ago in the mysterious depths of the Grand Canyon.
