We had a near miss yesterday in the Joffre area. We left from camp at motel 66 at 6am. With little recovery overnight we decided to climb Mt Hartzel.
We traversed below the N face of Matier about 250m from the bershrund in the flats. There where some old cornice debris in the flats and we made sure to stay further away as there was still one last cornice lingering up high. We summited Mt Hartzel around 10am. At 1030am while enjoying the views from the summit we witnessed first hand the upper cornice fail and trigger the entire N face of Matier to basal snow/ice. The crown was around 3m and the debris pile ran about 400m into the flats. Needless to stay our tracks got annihilated!
