Record 3 2007-09-17

English

Subject field(s)
  • Geomorphology and Geomorphogeny
  • Atmospheric, Climatic and Meteorological Phenomena
CONT

Steep gullies, filled with ice and snow, are a frequent source of avalanches because they combine several hazardous features :. Often slope angles exceed 40° so that slab and loose snow avalanches are frequent.. Several independent starting zones can occur on the sides and at different elevations.. The snow condition/stability can vary widely over the length of the gully, making evaluation difficult.. Snow deposition and characteristics are radically affected by the weather in a gully..... The difficulty of escaping to the side and the probability of hitting rocks magnify the danger for persons caught.

CONT
