Dock Marston Sport Yak 1963 - Glen Canyon Dam Visitor Center Exhibit
On our camping trip to Zion National Park and Bryce Canyon National Park, we made several stops along the way.
This is an exhibit in the Carl Hayden Visitor Center at Glen Canyon Dam.
The sign at the Exhibit reads: "This is a sport yak used by legendary River Runner Dock Marston on a trip down the Colorado River in 1963. Valves to control the water through the newly constructed Glen Canyon Dam were closed to allow minimal water downstream while Lake Powell was filled. Bigger inflatable boats and dories couldn't make the journey at the low water flow. "
". . .there is nothing - absolutely nothing half so much worth doing as simply messing about in boats . . . in or out of 'em, it doesn't really matter. Nothing seems to really matter and that's the charm of it." River Rat, Wind in the Willows

This is one of four similar boats used by Otis 'Dock' Marston and his expedition for a complete traverse of the Grand Canyon - Lee’s Ferry to Lake Mead, August 5-31, 1963. This trip included three other identical boats. The expedition was sponsored by the NPS to photograph extreme low river conditions after the gates were closed at Glen Canyon Dam. The "DOCK" also ran Cataract Canyon, March 28- April 4, 1964. Its final trip was on the Colorado from Whitmore Canyon to Lake Mead, May 5-12, 1965. The boat was backpacked into the canyon on the Whitmore trail for that trip.
