In the clearing weather, we could see this wide natural avalanche from late Sunday in Holiday Bowl, Upper Blind Hollow.

We visited Holiday Bowl, several days after it'd naturally avalanched during the powerful storm on Sunday12-13-09.

We climbed up this smaller pocket just south of the larger slide in the main bowl. It probably released at the same time the as the larger slide as it is only separated by a narrow rib

Here's a look at our results and our extended column test. The propagating failure occurred in very weak faceted snow just under the dusty layer.
