You do realize that you are using geological formations that illustrate and prove vast numbers of years in their formation. Great Unconformity in the Grand Canyon lends support to Hutton’s Unconformaty which led to his conclusions on deep time. I doubt you or the Creation Institute really want to go there.
I’ve noticed they do that a lot - point at one aspect of a geological feature as proof of their theory, while ignoring the implications of the rest of that feature.
Hi. One of the best places to start for modern understandings and explanations of catastrophic sedimentary deposits is from John Baumgardner.
Here’s a YouTube:

And here’s an example of his published work:
“Role of a low-viscosity zone in stabilizing plate tectonics: Implications for comparative terrestrial planetology”
