Green River

“We’ll never see them again,” thought the small crowd as they waved goodbye to the brave and possibly doomed men.

On May 24, 1869, an expedition made up of ten men left Green River Station, Wyoming, and started down the Green River.  The leader of this expedition was Major John Wesley Powell.

This was his first trip down the Green River to the Colorado River and through the Grand Canyon.  Three months later, and with only five of the ten men that started the expedition, the first party to ever traverse the Grand Canyon completed their journey.  In 1871, a second expedition made it possible for Powell to produce maps and scientific publications.  This opened the door for other river-runners to explore the aspect of fast water travel and boat design.
