Snow Survey Sampling Guide

For Special Conditions - Driving Sampler Through Layers of Deep Snow

Driving Sampler Through Deep Snow

When sampling deep snow, drive the sampler rapidly. Keep it moving continuously until the ground surface is reached.

The following procedure is suggested:

  1. Both surveyors drive the sampler with a hand-over-hand motion, keeping the sampler in motion.
  2. Grab the driving wrench handle and push down.
  3. If the tube stops, one surveyor steps on the handles and drives the tube down to the ground surface with a pumping action of the knees while balancing against his partner's shoulders.
