Abstract: A series of tests were conducted to determine if impressions in snow could be recovered from beneath subsequent snowfall. Various techniques were evaluated to determine which were most successful in preserving the detail of the original impression. It was found that a significant level of detail could be recovered. The various techniques that were tested are discussed and the authors provide recommendations on techniques they found to be most successful, which involved the use of compressed air. The effect of snow metamorphosis on the stability of snow impressions is discussed.
