Route & General Observations

Toured up Japanese trees from mile marker 10. Someone took off right before us so we followed his skin track. He pretty much followed the same skin track we took last week. Started around 10am and ended around 3pm. Made it up to frostbite. Didn’t do the last 100 feet bc the juice wasn’t worth the squeeze.

Observer Comments

Recent avalanche since 3/5 storm on a NE aspect on the ridge up to government peak. Seen when looking south.

After tour, larger roller balls off of arkose on sunny aspect. Saw these from the car. They weren’t there in the morning so indicated recent thaw from sun.

Weather & Snow Characteristics
Please provide details to help us determine the weather and snowpack during the time this observation took place.
Weather

24 degrees and sunny!
Once at 2800 feet, there was a slight breeze from the NE

Snow surface

5-9 inches of fresh powder on top of what felt like either a sun or drizzle crust.

Low density snow in the morning warmed up through the tour and stuck to the skis by the end of the day.

Wind effects evident after 2800 feet. Soft, small windslabs became more evident as we got higher. Didn’t do the last 100 feet of frostbite because it was a mix of ice and windslabs.

Snowpack

No pit dug today. Did several hand shear tests and the new storm snow popped out as a soft cohesive slab off the crust in several locations.
