Fortress Ridge North Runouts

We were on Lillian Lakes Trail where we observed a moderate debris field above and away from us on a runout zone. A small snow spout continually spilled fresh sluffing snow down onto the slope, causing smaller snow spilloffs down the runout of unknown smaller sizes throughout the day. Could not go to collect more information about the avalanche due to terrain hazards (likely requiring snowshoes) and risk of another avalanche in the runout.
