Geo 365: March 3, Day 62: Table Rock Rip-Up

A large rip-up (mud deposited and somewhat consolidated elsewhere, then ripped off the bottom, transported intact to a new location, then redeposited) and a few smaller ones at Table Rock. If you enlarge this, you can see the coarse, angular, and poorly-sorted nature of the sand grains in this deposit, which is fairly typical for sedimentary deposits at Table Rock. I don't know if anyone has ever done a detailed analysis and write-up of any significant portion of this volcanic/sedimentary pile, but there's a heck of a lot of detail to pay attention to. Apologies ahead of time, but I intend to spend yet another week looking at those details. We haven't even got to the "splort" yet.
