October 20, 1941: "C.J. (Charlie) Slade, Assistant Ranger at Arrowhead, was attacked by a grizzly bear on August 9th when climbing to Sproat Mt. Lookout with supplies. He was first grabbed by the hips and thrown to the ground. In falling he struck his head on a rock, getting a deep gash in his head and sustaining a slight concussion. He was then bitten around the hips and back and when the bear reached his neck Charlie thought his time had come, but something attracted the bear's attention and she left him and went to her cub. She returned and grabbed him by the right arm and shook him like a pup shakes an old sock. At this point Charlie does not remember exactly what happened but found himself 1 1/2 miles down the trail. He made the office and radioed Ranger Percy Young that he would have to go to the hospital. Assistance was sent immediately and he was taken to the Revelstoke Hospital, where he spent the next 10 days." (Forest Branch News Letter)
