Analysis of information sources in references of the Wikipedia article "Big Cascade Rapids" in English language version.
Two men "shooting" in their scow over the Big Cascade rapids, located on the Athabasca River. The Big Cascade was a seven foot drop in the river. Supplies going north or furs on their way to market were often lost when boats capsized. In high water it was easy to negotiate this rapid, but the water levels were low on this day and the scow was badly damaged, which made the rest of the journey more difficult.
