Figure 7. Sampling a 1-m2 area of snow next to a detonation point.
The scoops are very easy to use and quite effective when taking composite
samples (Fig. 8). It is easy to gauge depth, ensuring a complete sample is taken.
There is no spillage when placing the sample in the compositing bag. They are
lightweight and easy to clean. In some cases, the 20-cm scoop has been used in
difficult locations to acquire the large (m2) discrete samples. They do a thorough
job, but are slow.
