Normally, bark loosens from fallen trees. But the raft in the lake is a tiny fraction of the trees that fell and were buried. And you won't see peat there, because it takes thousands of years to form. The "Mt. St. Helens Peat" argument is only a "just so" story, with no evidence to support it.
So, the way the bark has settled compared to fossilized bark in coal...being the same...is a just so story?
