Observations document past conditions at specific times and places. They help inform the regional avalanche forecast but are not themselves an avalanche forecast. They come from various sources and cluster around popular destinations, which may introduce bias. We cannot vouch for the accuracy of observations submitted by individuals other than the SAC Forecasters and Professional Observers. A lack of reported avalanches does NOT mean no avalanches occurred.
