Big City Mountaineers (BCM), which serves youth in eight cities across the country, was founded in 1989 to instill critical life skills in underserved urban youth through transformative wilderness mentoring expeditions. BCM’s model is to partner with a vibrant network of youth-based agencies that work with under-resourced, racially diverse young people who often have no experience outside of their neighborhoods. BCM expeditions provide under-resourced youth with the tools and positive reinforcement needed to overcome obstacles and strive for a better future. BCM leverages the challenges inherent in wilderness adventure with a one:one mentoring model and time-tested curriculum designed to teach and empower youth. Since 2011, Polartec has supported BCM by helping the organization plan their youth expeditions. Together, we work to expose more young and diverse people to the outdoors, encouraging healthy living and conservation.
