Route & General Observations

Whilst atop tincan common & only moments after discussing with another recreationist how wild glide cracks were in the area, I stared at this looming glide to my north. “Matt” had just skied off & I began to hear noises as if a glacier was calving so I fumbled for my phone to take a picture. I could see a large hanging piece of slab buckle & obvious cracking textures appear on it. Phone went back in pocket & soon a chunk came roaring down the steep slope hitting & moving other pieces of this whole feature. Yet more moving of the entire slab commenced & 3 minutes later an even bigger, more violent pocket gave out, it tumbled & remained intact for a few seconds then disintegrated with the rest of the debris at the bottom. Quite a spectacle!

Observer Comments

Glide crack chunks released on two occasions 3 minutes apart, both at hot sunshiny SW aspect, apart of the same glide crack pocket. Could see the larger slab crinkle upon itself as it moved & could hear glacial noises coming from it as it crept.
