Avalanche on Round Top

Around 2:15 I was descending from the exit of Crescent Coiloir and made my way to the east above the lower bowl above Winnemucca lake. Attempting to find my way through some steeper terrain I made a cut across a section and at the snowboards edge a slab of wet snow broke and rapidly flowed down the mountain, becoming larger and entraining new snow as it went. With the violence as it went down it appaeared to create a small powder cloud and exposed some rocks. I was caught off-guard by the speed by which the snow avalanched and the planar nature as it was about a 6 inch slab that ran on a smooth surface. This would have been most likely an accident report if I had been any lower into the steeper part of the slope and it broke above me, dragging down through rock bands.
