This is very rare for the SAIS to issue a statement like this. Please read and take heed.
A terrain trap is a sharply concave part of the run out such as a gully, an abrupt transition or a crevasse where avalanche debris will pile up deeply. Since shovelling takes such a long time, deep burials have a very low chance of survival
SAIS – These are locations in the hills and mountains where the consequences of even a small avalanche can be amplified by the terrain a victim may be carried into. Narrow gullies and valleys, boulder fields, small buttresses and cliffs are places that limit your survival chances greatly if you are carried into or over them. Likewise when travelling above buttresses or boulder fields or through narrow valleys and below small banks be aware of the consequences of avalanches occurring from above, whether natural or triggered by human activity.
Please be careful if out and about Kevin Woods is climbing all the Munros this winter he does an update on Facebook. His journey this winter is a insight into Scottish winter with all its weather and incredible days. Even some of the so called easy mountains in winter have taxed Kevin and he writes honestly about safe travel. It is so important that all winter mountaineers are aware of the dangers in winter and how to make the mountains as safe as possible.
