I'm sure many of us have visited this area (south rim), as it's a destination for many of the charter Grand Canyon Tours. As I recall, there's a fair size wall and you'd need to be standing on it or climb over it to end up falling, which sounds like what happened.

Authorities investigating the death of a Texas man at Grand Canyon National Park believe he fell about 350 feet from the canyon's edge after trying to retrieve something, possibly a hat.

John N. Anderson, 53, of Grapevine, Texas, died Saturday after falling about 350 feet from the South Rim near El Tovar Lodge, park officials said. Witnesses reported seeing Anderson near a small rock wall that serves as a barrier between visitors and the massive gorge, but no one saw him fall, Grand Canyon Chief Ranger Bill Wright said Tuesday.

Wright said authorities believe Anderson was trying to retrieve something, possibly a hat, when he fell over the edge. The Grand Canyon Regional Communications Center received a report of a man falling around 8 a.m. Saturday.

Rangers found the man's body in a rock outcropping and began CPR, but efforts to resuscitate him were unsuccessful. A helicopter was used to remove Anderson's body, park spokeswoman Kirby-Lynn Shedlowski said.
