Observer reported via phone call. Party of two snowshoeing to access slope to snowboard triggered a couple audible collapses as they were assending. They came upon the fresh avalanche that had released lower on the slope than where it usually avalanches and buried the recent skin track they were following. The sight of the avalanche and other red flags caused them to leave the area, and when they got down to their sleds, they had to cross a pile of fresh natural loose wet avalanche debris from a steep slope next to where they had parked.
