Hieroglyphs at Grand Canyon

Mystery: If the 1909 Arizona Gazette story is true, what are the origins of alleged hieroglyphs at Grand Canyon? Is the covering it up?

Finding Egypt
Rumors of evidence for an Egyptian civilization is said to have been found at Grand Canyon National Park. The rumor spawned from an April 5th, 1909 Arizona Gazette newspaper article. However, the article states that the hieroglyphs were "possibly from Egypt", and it was only a theory.

The exact location of the site is not given in the article, but it says that it was part of a Colorado River expedition from Green River, Wyoming to Yuma, Arizona. The runs right through the Grand Canyon National Park where the alleged discovery of a "great underground citadel of the Grand Canyon" was made.

NPS coverup?
In 1956, a mid-air collision over Grand Canyon occurred between TWA and United Airlines, in zip code 86023, which is bordered by the along the entire length of the north end of the CDP. To date, the National Park Service has restricted the crash-site zone, will not disclose its location, and refuses to un-redact blocked information in the 1956 Mid-Air Collision over Grand Canyon incident report, under ARPA 1979.

In the 1956 incident report, the redacted statement is made: “The area of the Grand Canyon [ the identification redacted ] is the exacted location of the 1956 mid-air aviation accident”. It also mentions that the United crash site was in proximity to “discrete areas”. The NPS refers to both crash-sites as “managed as an archaeological resource” in a denied 2016 request for disclosure.
