This slide was triggered on our way out after riding Wolverine Bowl. Just above lake Martha snowboarder one rode down the slope and cut left toward the bottom into less steep terrain. Towards the bottom of the slope the slab broke above the rider and propagated to the riders right. Three other riders were able to ride down the slope to the lake with out any issue.

We did not notice any other activity or instability earlier during the day. However, a 2nd slide was observed while riding back to Brighton near Rock Garden.
