Glenn hosted an expedition down the Colorado River for the television program Expedition Earth, a show that, "...focuses on adventure, wildlife and environmental issues." The entire trip, which lasted about 18 days was filmed. Glenn served as the narrator for the expert team that was assembled. Glenn also provided the music. Some of which is on Strange Weather and some original compositions that were inspired by the whole experience.

Traveling with Glenn were expedition leader, Mike Boyle, Kirk Baker, the head of the Aspen Kayak School, Woody Calloway, a "Squirt Boat" expert and Nolan Whitesell, who specializes in the open canoe. Also along were the male and female world kayaking champions, Richard Fox and Myriam Jersualmi, who just happened to be newlyweds on their honeymoon.

Glenn looked a little nervous as he listened to initial instructions from Mike Boyle at the Phantom Ranch Put-In Point. "What do I do, hold on?" he asked. At first Glenn didn’t have to do much. While the others ran the first set of rapids, Glenn stayed behind and expounded on the history and design of the kayak.

Then it was time for Glenn to get his feet wet. The entire team got in a large, rubber paddle boat for a run down Granite Rapids. Glenn called it his "baptism by white water". Assigned the position of lead paddler, Glenn commented the it was like the first time he looked off the end of a high diving board. With Mike Boyle yelling, "Paddle, paddle harder! Paddle like you are going to die!" they took off down the rapids. After they made it through Glenn admitted, "I don’t mind telling you I was a little scared."

After this burst of excitement, it was time to relax a little. Glenn got a lesson on the geology of the area. At one point he contemplated his own existence after becoming aware that human existence is just a tiny, recent blip in the geological timeline. Glenn also delivers lessons on the Indians of the area.

The experts spent a lot of time playing in the rapids. After a particularly difficult run, Glenn comments that Woody had either a "..zen or ninja turtle focus".

One purpose of the expedition was to examine the threats to the Colorado River. Glenn outlined three major threats, The Glen Canyon Dam (an act of vandalism) which causes cold water to flow into the canyon and eliminates sediment, the Navajo Generating Station which causes air pollution and hazes over views of the canyon and several uranium mines in the area. Of particular interest was the humped backed chub, an endangered fish that has become a symbol for the negative effects of the dam.

Glenn found the whole experience to be eye-opening. "As days passed, I missed the conveniences of home less and less and began to notice all that was around me...my sense of peace and relaxation grew bigger." Glenn admitted that it was a powerful experience and the most remote place he had ever been.

Glenn took a double kayak lesson from Kirk Baker. Glenn admitted that you would have to be crazy to be let loose in his own boat. He did pretty well, though. He said, "I was impressed by the visceral sense of action and my humbling connection with the power of the river." Glenn pointed out several similarities between kayaking and skiing.

Fun loving Glenn had a blast On one particular tricky passage, the others shot ahead in their individual kayaks while Glenn, "….did my John Wayne impression and rode the bow of the oar boat like a bucking bronco."

Near the end of the trip, Glenn grew contemplative. With a face framed by 18 days of stubble he commented that environmentalism was important. "If we can’t protect this, what can we protect." Glenn then suggested that one solution to the problems of the earth was to raise a generation of environmentally conscious children. He said that conservation had to be as important a part of a child’s education as reading and math. Sentiments that would be echoed years later by his fellow Eagle, Don Henley.

The trip ended on a scary note. After a night around the campfire sharing the lore and legend of Lava Falls, the greatest challenge of the trip, the group piled into the rubber paddle boat and paddled away. Because of Glen Canyon Dam, the water levels in the canyon were dangerously low. The boat hit a rock and blew a pontoon almost at the end of the rapids. Glenn said, "I was hoping I wouldn’t get tossed out. All around us it looked like a big drowning machine." The group was lucky, though. They survived the mishap without injury. Glenn summed it up when he said, "Who cares about the boat? We’re all alive...but that was the longest 30 seconds I’ve ever spent!"

It certainly was a River of Dreams.
