Technician Andrew Linn, at left foreground in this winter photo, is crouched down to read the weight of a long, empty snow sampling tube hanging horizontally on scales attached to a scrubby spruce tree extending several feet above the snow. Knowing the weights of the tube when empty and when filled with a snow core sample was critical in calculating the moister content of the snow. A group of spruce trees exhibiting a wind-blown or alpine influenced character are obvious in middle ground with a diamond-shaped snow course sign attached high up on one. The sign acknowledges the Federal-State cooperative nature of the snow surveys. A partly tree-covered hill and faintly visible mountain are seen in background.
