Locomotive in the River

I found this photo in my father's collection. I have no information about it. All I know is that my father and his brother owned a large camera together in the 1930s in Chelan County, Washington. It appears that one of them must have taken this photo. I sent a copy of it to the Chelan County Historical Society, but no one seems to know anything about this accident. The family farm was in Peshastin, Washington, between Leavenworth and Cashmere, and the Great Northern Railroad ran along the Wenatchee River between Wenatchee and Leavenworth before heading over the Cascade Mountains to Seattle, so it seems most likely that the accident happened somewhere between Wenatchee and Leavenworth in the 1930s.
