Saw this avalanche in our travels today. I would think it happened naturally, closer to the tail end of the storm on the 16th or 19th, as the crown looked sharp. Maybe warming? In any case, this was a large avalanche. Look closely and see how far the gunners right propagated.

While this wasn't on Bomber Peak Proper, there is history here. "Bomber Peak is another summit on the Timpanogos massif, named because a B-25 bomber crashed into it. On March 9, 1955, the bomber took off from Ogden heading towards California. The pilot lost control and crashed into the eastern side of Bomber Peak just north of the summit. All 5 people aboard were killed and there is still wreckage of the plane on the mountain. It can be seen in the summer, but snow covers the wreckage in the winter. Bomber peak is comparatively left alone compared to the epic skiing off of North Timpanogos and the grandeur of skiing off the true summit of Timpanogos. However, Bomber Peak is worth a visit."
