Most dramatic was the show from 5-9pm Sat as we set high camp with repeated snow/sleet squalls separated by long views to Diamond peak and Klamath Lake, dramatic clouds, thunder close enough to touch. We encountered approx 8 other teams, all with the same outcome, the highest reported he got to 12000' before wind knocked him off.
