Sharon Kerfoot, a first-time visitor from Alberta said being able to view the terrain ahead of time, gauge the difficulty of the hike and know just how wide the path is would benefit those considering a trip to the Grand Canyon. She and a group of friends headed down the same path as Vincent but on mules, not foot.

“I think it’s an excellent idea to give people a broader perspective on what they’re getting into,” she said.

What the images won’t tell visitors is how much water they should carry down the trails, how to prepare for temperature changes, what type of food to take and how much, and how best to protect the natural resources, park spokeswoman Maureen Oltrogge said.

“Stitched together with other information out there, the technology could be valuable,” she said.
