Veteran mountaineer Dale Atkins was climbing the challenging Kelso Ridge last week on Torreys Peak, a popular Front Range fourteener, when he encountered a woman in her 20s who had discovered the complexity of the climb required route-finding skills beyond her experience level. “She said she’d gotten to one of the harder spots and just couldn’t figure out where to go, so she turned around,” said Atkins, a member of the Alpine Rescue Team, a volunteer search-and-rescue group that conducts missions in Clear Creek, Jefferson and Gilpin counties. “I asked her if she was using an app, and she said, ‘Yes, I was using AllTrails,’” he continued.
