When ascending the Dog Lake Ridge Line on Friday around 1200, our party noticed a slide that appeared to have occurred either much earlier in the day and or during the previous day. Time unknown. Slide not reported to the Brighton Patrol. Slide appeared to have been imitated by someone entering Girl Chute. Slide was approximately 50 feet wide at the upper crown and when it descended it propagated as it entered the lower bowl area of B bowl. Slide propagated to at least 150 feet wide. It appeared to have run in the same light density weak layer that has been observed over the past few days, 6 to 8 inches down.

PLEASE WHEN YOU SEE AND OR TRIGGER AN AVALANCHE, REPORT IT TO EITHER ALTA CENTRAL AND OR THE LOCAL PATROL.
