This pit was dug on a north facing slope at Lionhead. The ECT failed on 29 taps on large depth hoar crystas less than a foot off the ground. Although it would be difficult to trigger when it is this far under the surface, in areas wher the snowpack is thinner a snowmobiler could initiate a fracture that would propagate to deeper slopes like this one.
