The PDF above contains two vertical panoramas of the Grand Canyon. One version has the geology added, but the scale is such that it is difficult to read. I repeat the panoramas below but in a larger size so that they can be read easily. There is also an annotated view of the unconformity of the post Cambrian sediments on the Pre-Cambrian Grand Canyon Supergroup. A larger version of this is also shown below as a two photo slideshow - annotated and unannotated views.
