edge, all YEC's writing on the subject deliberately confuse the geological time scale with local stratigraphic columns. They do it on purpose. To mislead.
The first figure Faith provided shows how the local stratigraphy at the Grand Canyon (which, in itself, is a simplified diagram) relates to the geological time scale.
Oh, and Faith, the second one is a version showing the relationship between the different time periods. It shows, for example, that the Carboniferous Period occurred before the Permian Period.
The Carboniferous is a time period, Faith. Not a layer. The Permian is a time period, Faith. Not a layer. It really is not hard to understand.
