On a rocky trail in South Dakota’s Black Hills, granite spires propped above in the air, Alec Walker had a moment of rare personal clarity and fate. It was the spring of 2004, and Walker, a junior at TrekNorth High School, had sidled up with his science teacher for an ad hoc geology lesson on a hike.
They examined quartz crystals and feldspar, an expanse of granite tumbling ahead and out of sight. “I realized I could do this for the rest of my life,” said Walker, now an aspiring geologist and third-year student at Michigan Technological University.

Field-based epiphanies are a hallmark at TrekNorth, a public charter school in Bemidji, Minn., where outdoor adventure is regarded as a pillar to learning. The 7th through 12th-grade school, which has 165 students and 13 teachers, is based in a strip mall off Bemidji’s Paul Bunyan Drive. But it runs its extensive Outdoor Adventure Program to corners as far afield as Alaska and the Appalachian Trail.
The completion of a high adventure — from mountain climbing in Washington’s Cascades to backpacking a section of the Superior Hiking Trail — is a requirement for each student before graduation. “Wilderness trips are a catalyst for integrity, confidence and leadership in kids,” said Dan McKeon, the school’s executive director.
McKeon came to TrekNorth as an English teacher when the school opened in 2003, working his way up to become director three years later. A lifelong outdoors enthusiast, McKeon has roped up TrekNorth students to climb 200-foot-tall formations in the Needles of South Dakota. He has run dozens of trips, including paddling to far reaches of the Boundary Waters Canoe Area for eight days at a stretch.
He said students gain through day trips and expeditions by building traits impossible to achieve with chalkboards and books. “Students learn on trips that they are tougher than they realized, and can do more than they ever thought possible.”
