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.

This slide was triggered from this spot on the ridge above the slide. The lower angle slope below me cracked but did not slide.
Overview of the slide, taken from between the trigger point and the crown.
Looking a the skiers left side of the crown from the middle of the avalanche. Note the firm bed surface (the 12/15 rain crust) and the thin darker line in the crown just above the rain crust at the bottom of the new snow - the near crust facets.
Skier's right side of the crown and flank as the slope become lower angle to the skier's right.
Looking down the path at the debris and terrain traps below.
Small skier triggered loose dry sluff and a shooting crack on a N-NE facing slope around 8000 ft.
