Quick report
We teamed up with our friends at USGS to check the amounts and stability of new snow in Glacier National Park.
- We found 1 to 2 feet of fluffy new snow above 5000 feet.
- The new snow sluffed easily under our feet.
- Though avalanches were small, some ran long distances on the firm crust below.
- Steep and rocky terrain produced recent natural sluffs; again, these were small in size.
- Winds were calm during our tour. We found little evidence of wind effect.
We rode knee-deep powder one-at-a-time on slopes angled 30 to 35 degrees, and group skied on slopes less than 30 degrees. Pretty amazing mid-April pow day.
