Sierra Buttes Trail Stewardship
Strengthening mountain communities using trails as the tool
Help connect mountain communities, create jobs, and support economic growth through recreation.
Creating quality outdoor experiences in the Lost Sierra since 2003 through trail construction and maintenance.
Our work in the Tahoe, Plumas, Lassen and Humboldt-Toiyabe National Forests centers around building sustainable and resilient recreation-based economies through local job creation, responsible forest stewardship and increased recreation opportunities, and by hosting world-class race events.
The work performed by our professional trail crew and volunteers to maintain, restore, and enhance trails is done in an environmentally sensitive and ecologically responsible fashion, with the ultimate goal of fostering a connection between all trail users in the Lost Sierra and the public lands on which they recreate. Our mission is to help maintain enjoyable trail access for generations to enjoy.
