The snow sampling tools have been used extensively in tests in Alaska. The
shovels are effective but difficult to use. The sample bag used is slightly smaller
than the shovel, making placement of the sample in the bag difficult. The depth
of the sample is also difficult to control. Tests indicate that spillage during sam-
pling or insufficient sampling depth can result in underreporting of contamina-
tion of up to 15%. Sampling is quick but not as accurate as we would like (Fig.
7). The shovels are easy to clean.
