| Snow hardness readings should be taken in the center of each distinct snow layer and including ice layers which should be identified. Since we do not have a hardness gauge we will estimate hardness using the measurement technique (Hand Test) which is detailed on snow cards and commonly used by the professionals when they don't have a 'Hardness Gauge'.
THE 'HARDNESS GAUGE': Professionals use a hardness gauge which consists of disks of varying surface area. The technique is to slowly press each disc squarely against the snow and and use a scale which records a value indicating g/cm pressure at which the disc begins to enter the snow. PERFORMING THE 'HAND TEST' TO DETERMINE SNOW HARDNESS: This is a test that requires the use of the hand, a pencil and a knife. The procedure is to gently determine the penetration of each test into the designated spot in the profile. These spots will be in the layers that were previously identified (Protocol 3). Gently push the fist, fourfingers, one finger, a pencil and a knife into the snowpit study face and determine which item begins to penetrate the snow surface (with gentle pressure). Use the following scale to determine the hardness of the snow in g/cm2
