Incident Name: Grizzly Fire on the Lower Trinity Ranger District of the Six Rivers National Forest
Date: 7/25/69, 1300 hours
Personnel: Richard R. Rosvall
Age: 30 years
Agency/Organization: a US Forest Service helicopter
Position: Helitack Foreman at Ammon Helitack (near Salyer, now gone), Lower Trinity R.D., Six Rivers National Forest from 1966-1969

Summary: On July 25, 1969, Richard Rosvall was acting as helitack foreman for a Forest Service helicopter that was fighting a fire on the Six Rivers National Forest near Grizzly Camp on the boundary of the Trinity Alps Wilderness. The Forest Service helicopter was delivering firefighters to the Grizzly Meadow mountainside. It touched down. One or more firefighters left the ship, apparently causing it to lift as he (or they) stepped off the skid. On the uneven ground the helicopter became unbalanced and the pilot lost control. The main rotor struck the ground and then the rotor subsequestly struck and fatally injured Rosvall who had exited.
