This appears to be a little more treacherous than I imagined. Where is the trail? Around the tree and down the side of the cliff?
Armand is probably Guiness World Record material, in more ways than one. I truly doubt that there's been anyone older who has hiked down the canyon. A Google search for "oldest+hiker+grand canyon" results in posts about the oldest rock formations.
Let's have an Armand siting! This Thursday, October 26. The Bright Angel Trail. I'll send you some Kona coffee if you're the first one to provide me with a photo!
