## Narrative

My determination is the cribs that were constructed were on loose bottoms and or frozen bottoms that a scoop could not get to as per the original prevention support plan. The pressure from the fall continued in-by xc9-10 entry 6 on the 1 MW causing the cribs to fail due to sinking and shrinking of the wooden cribs. The cribs in the fall area were not constructed properly.
