Re: Suspicious impact craters and iridium layers?

[Phil Bigelow <bigelowp@juno.com>]

Could this explain the deeply-channeled Bug Creek beds?  Massive
post-impact rain storms over the Laramide highlands?

Some sed. petrologist should look carefully at the provenance of the
mineral constituents of the Bug Creek sandstone and search for components
not commonly seen in the underlying (K) sandstones.  Maybe new source
areas were eroding immediately after the impact.
