Thanks for responding.
One of the main features of Walter Browns model is a subsequent flood in the Grand Canyon area which would take place when trapped waters burst free. I have personally played with water and mud dams, and the shapes of the formations match up very well with my results.
I know others are looking at "secondary flooding" as well. I think many, if not all of the features in question could probably be accounted for with little problem.
If a discussion were restricted to a single location, I might be more inclined to participate. As it is, as soon as one is accounted for more and more will be brought in. It's how the game is played around here.
For any creationist taking up the challenge, don't get suckered in to any phony flood model where there was no earth prior to the flood (flood must account for lowest rocks), or where no other local floods have ever taken place. The flood is not a simple event as evolutionist straw man models must always make it out to be. And there may have been considerable tectonic activity both during and after the flood.
I'm not aware of the meteorite issue, but I know about the pole reversal thing. There's no need to call anyone a liar for not believing in them. The evidence is slim, and subject to interpretation. And there's no reasonable mechanism which would cause such an event.
If anyone earnestly wants to discuss an angular unconformity which they think 'disproves' the history of the flood, they're welcome to email me: dstew8 at excite dot com. I may be slow to respond, but I'll try to help. I'm no expert, but I haven't yet found an issue in evolutionism which requires an expert to debunk.
