Observer Comments

Recent (today) skier triggered slide on lower half of Skyscraper above the parking lot, whumphing. Talked with another group who had significant whumphing in the flats at the bottom of Pinnacle bowl. We split from the road up the low angle slope towards gold cord mine and experienced a massive whumph. Due to the size of it and the recent snowfall and slides, we bailed on today's plan. Experienced a smaller whumph on the very short ski out back to Independence mine.
