GRAND CANYON MYSTERY HDTV

It's been 70 years since a honeymoon couple disappeared in the Grand Canyon during what would have been a record-setting rafting trip -- the fastest river trip on the Colorado River, the first through every rapid and the first by a woman.
Idaho farmer Glen Hyde and his bohemian wife Bessie almost made it. They traveled 600 miles on the Green and Colorado Rivers in a massive wooden boat called a sweep scow. The boat was found intact, still holding the couple's food, diary, guidebook, gun, clothing and boots, just 46 miles from the mouth of the Grand Canyon. But one of the biggest-ever Grand Canyon searches failed to turn up any sign of the honeymooners.

Ever since, Glen and Bessie Hyde have been the focus of campfire stories. At least four apparent Glens and Bessies appeared in later years, triggering legends of miraculous escapes. One woman claiming to be Bessie spoke up on a Grand Canyon river trip after listening to the story.
