Defend our National Monuments

In May 2017, the Department of Interior announced an unprecedented review of 27 National Monuments, including four monuments with mountain biking opportunities that IMBA chapters and advocates worked for years to secure.

What is IMBA doing to protect National Monuments?

IMBA is working hard to protect these threatened monuments by raising awareness, working with local stakeholders, encouraging public comments from mountain bikers like you and submitting its own letter to the Department of Interior to advocate for our public land and the public process that influences these areas. The threat against National Monuments is part of a broad attempt to undermine our public lands and IMBA will work tirelessly to protect the places we ride.

Why are National Monuments important to mountain biking?

National Monuments allow many types of recreation, including mountain biking, and have become a great tool in the mountain bike toolkit to preserve places we love to ride. National Monuments are established by Presidential proclamation using the Antiquities Act of 1906 to protect areas that contain significant natural, cultural, or scientific features representative of our American heritage. Striking the balance between preservation and recreation allows the American public to directly experience the uniqueness and special character of these areas.
