A long-running counterculture festival, now in its fifth decade and scheduled to take place over the Fourth of July holiday, is being canceled, citing U.S. Forest Service officials' lack of appropriate permits and concerns about environmental impact.

The Rainbow Family of Living Light gathering was scheduled to take place in the Plumas National Forest in California during the first week of July. However, on June 25, U.S. Forest Service officials issued an order ordering people to leave the area. Anyone who refuses to do so faces fines of up to $5,000 or six months in jail.

“The Forest is concerned about the 500+ individuals already scattered camping in a concentrated area. We are always willing to work with any organization or group interested in recreation on the National Forest. There are existing and projected impacts to natural and cultural resources and other authorized uses. Our priority is maintaining public health and safety and appropriate management of public lands and natural resources,” Plumas National Forest Superintendent Chris Carlton said in a statement Wednesday.
