A man suspected of using a knife to confront a rafting party along the Chickaloon River has been charged with four counts of felony assault.
Alaska State Troopers say 56-year-old Bruce Harrison of Chickaloon, claiming the group was trespassing, on Monday untied a raft carrying five juveniles and kicked it into fast water toward rapids.
A guide swam to the raft and took control of it.
Online court records Tuesday did not list an attorney for Harrison.
The incident began when one of four rafts from Nova River Runners overturned, putting juveniles in the water. The four rafts tied up on the east bank.
Troopers say Harrison confronted the rafters, claiming they were trespassing, and threatened a guide who attempted to explain the situation.
Harrison was jailed in Palmer.
