Georgie White Clark - adventurer, raconteur, eccentric - came to know the canyons of the Colorado River by swimming portions of them with a single companion. As she subsequently hiked and rafted throughout the region, she increasingly shared her trips and love of the river with friends and acquaintances.<BR>Georgie, a conservationist and nature lover, saw the Colorado River and her sport change with the building of Glen Canyon Dam, enormous increases in the popularity of river running, and new National Park Service regulation of rafting and river guides. Adjusting, though not always easily, to the changes, she helped transform an adventurous sport available to only a few into a major tourist activity. She was eighty years old when, at the helm, she guided her last boatload of passengers down the Colorado.
