Pardon the plain talk, but Woodmorappe's work is total crap. I refer people

If you read YEC papers, you'll see that they can't agree on where to place
the upper OR lower boundaries of the so-called "flood" deposits. Henry Morris,
for example, argues that it's "mandatory for Bible-believing Christians" to accept
his view that essentially ALL fossil-bearing strata from late Proterozic through
Tertiary are flood deposits (Morris, 1996). Other "flood" geologists place the
flood/post-flood boundary at the Cretaceous/Tertiary boundary (Austin, 1994,
Vardiman, 1996). Maybe they're not bible-believing Christians? Some, like
Froede (1995), argue that since YEC's can't agree, that they should abandon all
reference to the standard geologic time scale and propose a YEC time scale. In
that scale, there's Pre-flood strata, Flood strata, and Post-flood strata (so the
"flood" strata is whatever the heck they say it is and they can ignore those messy
stratigraphic correlations that mainstream geologists have so painstakingly worked
out over the past century! In other words, that allows them to locate the flood/
post-flood boundary in the Cretaceous in one area and in the Tertiary somewhere
else. How convenient!). YEC's use mainstream geology when it supports their
preconceived ideas about Noah's flood and ignore it when it doesn't support them
(it's called selective use of evidence).
