A longtime counterculture festival now in its fifth decade and set to be held over the July Fourth holiday is being shut down, with U.S. Forest Service officials citing a lack of appropriate permitting and concerns over environmental impact.

The Rainbow Family of Living Light gathering was set to be held the first week of July in California’s Plumas National Forest. On June 25, however, the U.S. Forest Service officials issued an order asking people to leave the area, with those who refuse to go facing fines of up to $5,000 or a six-month jail sentence.
