I unintentionally, but not surprisingly, triggered a soft slab in the north chute of East Mineral. It broke about 10 feet above me on the steep roll over where it always breaks. I saw it crack and easily skied off the slab avoiding what could've been a ride down the chute. The weakness was within the newer snow about a few cm above the dirt layer. This was identified prior to the avalanche. It is interesting that this weakness is still somewhat sensitive 3 days after its formation. It's my opinion that you need a slope approaching 40 degrees to get these types of slides to release.

Here's a totally different type of instability that I observed.
