KeywordsSnow sampler lateral sampler

The sections of duraluminum snow sampler tubing were screwed together. A strip of cold-rolled steel 1/16 X 1/2 inch moved freely through guides supported on the inside of the tubing. The slide bar was permanently bent at the cutter end so that it would lay flat against the tubing when driving but would curve inward when pushed towards the cutter end. The tube was then rotated one turn to cut the core free from the vertical face of the hole face. The tube and core withdrawn and weighted to obtain the snow water equivalent of the driver and by noting the length of drive it was possible to compute the density of the snow in the horizontal section. The sampler with this modification cut the retained core within 05% of the sampler drive.
