Comments
two people crossed the toe of this slope in an area that was believed to be safe. Several minutes later when the remaining four people transited that same area, following the same skinyrack, the slide happened. Approximately 30 to 40 m of the skin track got buried under a thin layer of snow debris that washed down the slope.
