The Earth Day 20 Foundation highlighted its April 22 activities in George, Washington, near the Columbia River with a live satellite phone call with members of the historic Earth Day 20 International Peace Climb who called from their base camp on Mount Everest to pledge their support for world peace and attention to environmental issues. The Earth Day 20 International Peace Climb was led by Jim Whittaker, the first American to summit Mt. Everest (many years earlier), and marked the first time in history that mountaineers from the United States, Soviet Union, and China had roped together to climb a mountain, let alone Mt. Everest. The group also collected more than two tons of trash (transported down the mountain by support groups along the way) that was left behind on Mount Everest from previous climbing expeditions. The master of ceremonies for the Columbia Gorge event was the TV star, John Ratzenberger, from Cheers, and the headlining musician was the Father of Rock and Roll, Chuck Berry.
