Size 2.0 Na noted yesterday on approach to Sapphire Col. Lots of similar (but bigger) slopes left so we skied somewhere else. Also noted: - a size 2 Na on a SE aspect of Glacier Crest at approximately 1850m that was likely from sometime between Feb 23 and Feb 24. - The Dome roll had run full width probably during the storm of Feb 22 . Likely size 3.0-3.5 but could just make out crown (re-loaded with 25 cm's low density HN). - A size 3.0 - 3.5 from a NW aspect high on Lookout Peak running down into Lookout Bowl, likely from Feb 22 storm. - Lots of debris in the Rampart Path from numerous storm slabs also initiating during Feb 22 storm. Sun in AM in Asulkan Valley created a thin crust on East aspects over 30 degrees or so. This affected ski quality on the standard Dome exit down the skiers left side of the Rampart path.
