[[Also, the presence of fossils.]]
Mt. St. Helens has em- fossilized trees- instant fossilization complete With Sediments!:
“The Specimen Ridge fossilized tree trunks are reminiscent of the enigmatic polystrate fossils discussed in the previous chapter. Polystrate (i.e. “many-layer”) fossils are evidence against an old earth because their existence argues that the several layers encasing them had to be deposited quickly, and at one time. In order to produce a fossil, an organism must be buried rapidly so as to seal it off from the decomposing affects of air, insects, bacteria, etc. Prior to the Mount St. Helens eruption, scientists were at a loss to explain how so many uprooted and dead trees might come to buried in an upright position. Discoveries at Spirit Lake, in the blast site immediately north of Mount St. Helens, revealed the answer.”
