Yes, in my haste I did oversimplify the situation here. In different
places in the park many of the "forests" are clearly the result of
transport in mud and debris as most of the tree are in fact not standing
and stumps are not rooted in a "fossil" soil. There are some trees that do
appear at least to have been covered by ash or where at the bottom of a
valley and were surrouded my mud rather than be transported.
The fossil forest didn't really have much to do with my question.

Your answer to my volcanic cooling question was about what I thought:
Nothing ever is as simple as it first seems unfortunately. It seem that it
would be safe to say that there could be enough unknowns in any equation
that I shouldn't use time for cooling as an argument that a world-wide
flood couldn't have happened only 4000 years ago. This is what I needed to
know. Thanks.
