Fragments by size 0. divided into large (with debris, comparable to the human body), medium (size of debris larger than the shoe) and shallow (less shoe with debris). The slopes are small pieces on top. of 0., large — at the bottom. The steeper the slope and the smaller 0., The more likely it slipping under load, especially if it is a solid smooth substrate, for example. on rock slabs, glaciers. Mobile (Ie n. live) 0. can carry along the unwary tourist, cause rockfall. Especially dangerous are they over rock dumping, steps to-rye difficult to notice during the descent.

Ice ax is used as a support for climbing the big rocks. When driving at an average of 0. very important to recognize the early "live" rocks to try not to stand on them to get round.
