Comments
Natural size 1 must have happened after the last 5cm fell overnight and sometime before 10am, as there was no fresh on the debris. This was on the large open convexity at the "false summit" - that's what it is to me anyway. Broke just past the roll over. Two cracks propogated to a flatter slope that did not slide. Tried to cut it more on my way down and it didn't move.
