Was watching a snowboarder ride down the tree'd ridge off the top of Rocky Point. He made a few cuts on the rolls next to the main gut. He seemed to get a couple stuffs to run slowly. On a roll further down the slope he made a cut into the gully which seemed to trigger the slab or it could have been a combo of him and the sluff. Anyways he moved back onto the ridge and out of the gully and was clear of the slide. The slide didn't run very far due to the slope mellowing out in steepness. The slide ripped close to the ground and is a repeater I assume. The slide was 18 inches deep max. but probably averaged about 8 or so inches. I didn't take too close of a look at the crown but it seemed to be mostly the new snow failing on the bed surface basically on the ground.
