Comments

Steep Terrain/Chute that comes off the North Ridge of the Dog Lake Bump. This path strikes the Summer Trail from Lake Mary heading to Lake Martha. Very Steep and Rocky. Hard to say when this went. It could have been as recently as the same day that the Rocky Points Slide went/12/26. Crown looked fresh, yet there was some new snow on the debris and runout. Either way, it went to the ground. It may have been remotely triggered by folks ascending and or descending the easy out down the Dog Lake Shoulder.
