Skied into Bunchgrass yurt on Friday Feb. 6th. On the 7th we observed an avalanche along the corniced ridge south of the Christmas Tree run. I suspect that it was a natural release that occurred late Friday or early Saturday, because we did not see the slide on our ski in. It released below the cornice and I would estimate that it was 200 - 300 feet wide and ran approximately 50 - 75 feet to the break in the slope.
