Archaeologists are excavating sites along the Colorado River in the Grand Canyon in hopes of saving artifacts before they wash away.
Although the National Park Service typically leaves such artifacts alone, about 60 sites are being undercut by water, or unearthed by wind, topography, and a lack of sand, which is largely blocked from getting into the canyon by Glen Canyon Dam upriver.
