The Zipper on the north face of Lane Peak

March 17, 2019, 11:30 a.m. PST

Weather: Warm, clear, and sunny though the route was shaded throughout our climb and the day.

Snowpack: Consolidated base with loose snow on top and a thin crust early in the day. Older pinwheels and rollers where seen on sunny slopes.

Area Description: Lane Peak in the Tatoosh Range of Mt. Rainier National Park

Avalanches: A moderately sized loose wet avalanche caught my party of two and another pair near the top of the route. It appeared to have traveled down a side gully before entering the main chute. One person was able to hold one, a second was swept about 20 feet and two others were carried a few hundred feet down. All parties were uninjured. My partner and I finished the climb as the quickest way to get out of the chute. The southern facing descent route was a complete debris field, which we crossed as safely as quickly as possible. After we crossed we witnessed another moderately sized loose wet avalanche within the debris field. On the rest of our descent we saw active rollers and pinwheels.
