Observer Comments

I remote triggered a moderately hard slab approximately 8-14 inches deep and about 60 ft wide. I was skinning on the trail underneath a convex rollover. I felt the slab tension and continued as a slope test. Then it broke about 50 ft above me and ran down onto the trail. Due to the large chunks and lack of momentum it did not hit me.
