Assume a team of 2-3 people intend to traverse a very exposed ridge at altitude. What are the main hazards and how can they be mitigated?
The type of ridge in question is covered in snow (various types of, maybe even some ice) and falls off steeply to both sides. The mountaineers follow the ridge to ascend/descend from a peak, generally following the highest point or close to the highest point of the ridge. The inclination of the ridge itself can vary from up- to downhill and various steepnesses (an answer may need to specify applicable steepness for different techniques). Examples of such ridges are the Piz Palü traverse or Bianco ridge to Bernina.
