Observations

Multiple cornices observed on Eastern aspects of the Mile Canyon at Timberline. Cornices were wide spread across the canyon wall and reactive to kicking. Most collapsed with less than 5 kicks. Some with a single kick. Cornice fractures propagated up to 15 feet in length in front of us. Multiple cornices fractured into blocks between two and four feet tall.
