Undine was a stern-wheel steamboat, built in Rock Island, Illinois and shipped to Green River, Utah, and launched in November 1901 by its owner and captain Frank H. Summerhill.
Summerhill intended to serve a tourist trade from Green River to the Colorado cataracts as the prime source of his income.
However he also intended to begin a shipping business up the Grand River, to Moab.
He spent several mouths blasting rock hazards out of the Grand on the route, then attempted an ascent.
After several attempts resulting in snapped cables, it ascended the first rapid but at Big Bend, while ascending rapids with the cable, Undine's bow was caught in a current and it capsized, wrecking it on May 21, 1902.
