Some 20,000 ambassadors from the global counterculture are making their way to Skookum Meadow, high in the Cascades east of Swift Reservoir, for their annual July Fourth celebration of nonviolence, peace and sustainability. Organizers of the Rainbow Family of Living Light are working closely with Gifford Pinchot National Forest managers on traffic and environmental issues and holding community meetings to address local concerns. One such meeting was scheduled for Monday evening in Stevenson; a second is set for 7 to 9 p.m. Friday at the Yale School gym.Since 1972, the Rainbow Family, a loosely affiliated group of individuals committed to principles of nonviolence and alternative lifestyles, has held its annual U.S. gathering on national forestland. The group had initially considered the Colville National Forest in northeastern Washington for this year’s meet-up, but reportedly shifted its sights to the southwest after learning that this year’s cool, wet spring promised a bumper crop of mosquitoes on the Colville.Law enforcement officials are taking the gathering in stride.Skamania County Undersheriff Dave Cox said the county is taking its lead from the Forest Service. “We’re in a support mode for them,” he said. “We’re basically doing the fire, EMS and peripheral law enforcement. “Christy Covington, public affairs spokeswoman for the Gifford Pinchot National Forest, said Forest Supervisor Janine Clayton met with members of the group in early June and later joined them on a field trip to the 40-acre Skookum Meadow site, a large wetland, part of which is still under deep snow at an elevation of 3,200 feet. An advance “seed crew” is at the site hand-shoveling snow this week, she said.
