These pits are generated using a FREE and easy to use program available at www.SnowPilot.org. Through Snowpilot, snowpit data can be uploaded to a international database for use by researchers to study avalanches.
Watch a video that shows how to download and use the software.
Go to either the AAA page about Snow, Weather, and Avalanche Guidelines (SWAG), or NAC websites to get detailed guidelines on snowpits and stability tests.
This snowpit from Bell Lake was dug by a level one avalanche class six days before a skier was killed in an avalanche on a slope nearby. Between the time this pit was dug and the time of the fatality, this area received steady snowfall which increased the weight and thickness of the slab overlying the weak interface at 130cm.
