Avalanche: Turnagain

Location: Seattle Ridge

Route & General Observations

Skied N, W, and E aspects around Seattle Ridge. Had several small windslabs break at our feet throughout the day. These were contained to the new windloading and were 6 – 9 inches deep. Triggered one slightly larger slide while dropping into an obviously loaded chute. Again it was contained to the newly windloaded snow. Its dimensions are described in the avalanche details section. Interestingly, the next chute over which was steeper and had a larger wind pillow did not slide upon ski cutting.

All observed signs of instability in avalanche terrain confined to newly windloaded snow.
