agesilaus...I've never heard of the "East Rim". That section of the article seems to be based on the writer's conversation or visit with the owner of a tour business. I looked up their website. My guess is that they take you to an overlook on a dirt road off Hwy 89 between Cameron and Page, which is on Navajo land. He mentions the confluence of the Little Colorado River and the Colorado River, which may be where he takes his customers. I imagine it's a lovely sight, but I think it is him naming this overlook as the "East Rim". It is not in the National Park nor is it a "defined park".
And the photo of Antelope Canyon, with the caption "Antelope Canyon in the East Rim" is a little ridiculous. Antelope Canyon is in Page, AZ...nowhere near what could possibly be considered the East Rim of the Grand Canyon.
Bottom line...I think this bit of the article is mainly about the business, Sacred Edge Tours.
Looking at my map, the confluence of the Little Colorado and Colorado rivers is in the GCNP. I think the writer is just stating that this area(East Rim), is geographically the eastern part of the Grand Canyon National Park the same way as the South and North rims are mentioned to give some geographical perpesctive on where they are.
BTW, the confluence is not easy to get to so the clients were probably driven to a look out a long way from the meeting of the rivers athough having only hiked there from the Tanner trail up river, I could not be sure of this.
