Glen and Bessie Hyde, last seen, November 18th, 1928, (Last Diary Entry November 30th, 1928), Colorado River, Grand Canyon National Park, Arizona.

Bessie Hyde and her husband, Glen, set off on a honeymoon trip on the Green and Colorado Rivers in October 1928. In those days, the Grand Canyon had no commercial river trips and the rapids were for seasoned explorers and professional expeditions only. They had no life jackets or specialist wet weather gear. Certainly not a trip for a pair of honeymooners in a homemade scow called Rain in the Face. Confirming the dangers, early in the trip, Glen fell out of the boat on a rapid.

The Hydes met on a passenger ship travelling to Los Angeles in 1927. They were married on April 12, 1928.

Glen was an expert boat builder who built the 20-foot-long wooden sweep scow and had rafting experience on the Salmon and Snake rivers in Idaho a couple years earlier. In contrast, Bessie was a novice to rivers and rapids. Glen was determined to set a new speed record for travelling through the Grand Canyon, and he wanted Bessie to make history as the first documented woman to run the canyon.

Bessie Hyde, 22, was an aspiring poet, artist and bohemian. According to the late Otis "Dock" Marston's library, the Hyde's plan was that they would run the canyon, then go on the lecture circuit and make money retelling their adventure.

The couple were last seen on November. 18th, 1928 and their scow was found in early December, around three weeks later. It was found floating upright around River Mile 237, and filled with belongings and the supplies were fully strapped in. But Glen and Bessie were nowhere to be seen. There is evidence they made it as far as River Mile 225 where they may have made camp. A huge search turned up no trace of the couple.
