Paige took a look at this 1/27/17. There were no tracks leading in to the slope from the top though there were lots of sled tracks just a short way to the north. Possible it could have been remotely triggered from there or from below as folks riding up the canyon will sometimes carve up the lower part of the path. The deposition covered the existing snowmobile road. Hard to tell how deep but up to at least 6' in some spots. Definitely failed on buried surface hoar.
