    Four teenage girls from Minnesota, US. 120 hours of non-stop togetherness. No cellphones. This is not a reality show, but an adventure journey.

“It was really perfect,” said Julia Ruelle of her recent adventure to the Boundary Waters Canoe Area Wilderness with three of her childhood friends. “By unplugging, we had an amazing time.”

Last year, the 16-year-old took part in an essay contest and carried off a prize. The award was a 5-day canoe and camping adventure with up to three friends. No parents or guides would be there.  So Julia invited her friends Anna Wander, Madeline Wilson and Julianna Torelli.

The four Minnetonka High School juniors arrived in Ely for training the day before they began the journey. They set out the next day at 7 a.m., quickly developing a routine.

“We were done paddling by noon,” Julia said. “We ate lunch at the campsites and then it was time for hammocks(吊床), reading, making friendship bracelets(手镯)and talking.”

The girls had all had experience in the outdoors before.

Anna had been to the Boundary Waters with her family. “I love how you are separated from everything in your life, especially technology,” Anna said. Without her phone, she said, “I’m less worried about things.” Madeline, too, had been to the Boundary Waters a few years back. “But this time, I had to paddle right and set up camp,” she said. The girls made fire and cooked meal together. No one was ever hungry or homesick, but they were nervous the final night as they waited out a thunderstorm. They left wet sleeping bags in one tent, and squeezed into another for the night. “Every thunderstorm in the Boundary Waters feels huge,” Julia said.

On the car ride home, they were all on their phones catching up with friends. “It was a little at a loss turning my phone on,” said Anna. “Mental health can be improved so much in the Boundary Waters. It really helps to get away and reconnect with yourself.”
