"When a group of teenagers set out to hike British Columbia's famed Howe Sound Crest Trail in early July, Google Maps suggested the trek would take about five hours," reports SFGate. "Instead, the hike stretched deep into the night, leaving the group exhausted, dehydrated, injured and in need of a helicopter rescue..." Although the approximately 18-mile route with a 6,000-foot elevation gain can be completed by experienced trail runners in a day, search and rescue officials generally recommend hikers treat it as a two-day backpacking trip. The teenagers, all 17 years old, believed Google Maps' estimate that the route would take about five hours. The printed directions they were carrying, which were shared publicly by Lions Bay Search and Rescue, gave simple instructions for two legs of the trail, but didn't account for the terrain or elevation. "[Google Maps] is calculating the time that you're walking a straight road on pavement," [said Maria Masiar, training officer and search manager with Lions Bay Search and Rescue]. "When you get into outdoor terrain, that no longer holds true." Expecting only a short outing, each hiker carried about half a liter of water and limited food. There are no reliable water sources along the trail, meaning hikers must carry enough supplies for the entire route. As the group climbed, they began suffering from dehydration and muscle cramps but continued onward despite falling dramatically behind schedule. Eventually, the group made the decision to turn back and abandon making it to the end of the trail — and as the sun began to set and the group started to descend, fatigue took its toll. According to Masiar, members of the group had already stumbled and fallen several times while trying to race the coming dark, and only one hiker had a headlamp. Eventually, another hiker slipped about 10 feet off a boulder, injuring his tailbone badly enough that he could no longer continue. Search and rescue crews responded, ultimately evacuating him by helicopter.
