Ill be looking for time gaps that are significant in earths history
The HAdean base
The top of the Grenville or Canadian SHield
The base of the CArboniferous
The Permian/ Triassic boundary
Any significant uncomformable features like a metero strike or a tsunami track, flood deposits, dune deposits, loess hills with cross sections
This is gonna be a text with lots of pix. The organization is whats gonna make it a usable work.
All these unconformities will, of course, have to be located within 50 miles of a really great restaurant.
