Bottom Line

We traveled up towards Point Six behind Snowbowl. We found a snowpack that was unconsolidated with a height of 80 to 90cm. We dug a pit above Jenny bowl and performed 3 extended column tests. We had no propagation in our tests. Due to a thin snowpack and an almost complete lack of base, we skied with caution.
