These observations document past conditions at a small and variable scale. They are not to be confused with an avalanche forecast. They come from a variety of sources. We can only vouch for the quality of those produced by the SAC forecasters and professional observers.

Avalanche Observation 		Red Lake Peak - Above Crater Lake
Carson Pass Area 		Just before the avalanche was triggered. The skier that triggered it just did a ski cut and then a few more turns with no reaction other than loose sluff. The avalanche would be triggered on the next 1 or 2 turns. The skier that triggered the avalanche took this photo of the loose dry sluff just before the avalanche was triggered. Avalanche debris field. The path dog legs out of sight to the left. Looking back at the upper path of the avalanche. You can ski where the skier went over the buried rocks but was able to ski to safety. The upper crown is 12-14" and lower crown 24-30". Overview of avalanche crown. The first ski cut is visible as well as where the skier stopped after releasing the loose sluff. 24-30" avalanche crown Upper bowl of Red Lake peak is visible with previous ski tracks. The lower part of the avalanche path is obscured by a small ridge line with trees. Public
