Step 1: Prepare
- Start the Mountain Hub App. Doing this before taking your measurement will give your phone the time it needs to accurately find its position.
- If the app was already open on your phone, close it (double tap the home button, then swipe up on iOS) and re-open it.
- Take off your pack and assemble your avalanche probe or measuring stick.
Step 2: Measure
Use your avalanche probe to measure the depth of snow to the nearest centimeter:
- Find a representative area in undisturbed snow to make your measurement. For example, avoid tree wells, or spots where skiers and snowmachiners may have compressed the snow.
- Push your probe firmly into the snowpack down to the ground. Make sure you push firmly to make sure you are measuring to the ground and not intermediate ice or dense snow layers.
- Read the snow depth on the probe from ground level to the nearest centimeter at the snow surface.
- If possible, repeat 3-4 times in a small radius (<1 m) and take the average of those measurements.
- If the snow depth is greater than your probe length, use your shovel to dig a shallow pit (~50 cm or so) with a clean vertical wall. Push your probe firmly to the ground in your pit. Mark the top of the probe on the vertical wall of snow. Remove your probe and use it to measure the additional distance from the mark to the snow surface. Add the two numbers and you’ll have the total snow depth!
Step 3: Record
