Soft slab failed on pollution layer / fertilizer / grass interface. Unintentionally triggered by fat tire snow bicycle. Slide went unnoticed because photographer and bicyclist were looking at the photo of riding powder on a bicycle when a bi-standder sledding in park with his children said "oh wow an Avalanche.." Debris pile was about 2.5 feet deep.. This is not meant to be a joke just an interesting observation as urban avalanches should not go un noted..
