On The Ground Impact
For over 40 years, RMFI has cared for Colorado’s public lands. Here’s how that legacy has shaped our treasured landscapes.
1,610,000 pounds
Of Rock Moved since 2019
To craft each rock step you use on the trail, each retaining wall that keeps the trail and hillside in their place, each drainage crossing that prevents erosion, mud, and trail damage, and every armored corridor of trail—each carefully selected rock is carried and meticulously placed by hand.

Our Why
Check out the fabulous video about "Our Why" filmed and created by Rob Hoff Imagery.
The staff on this event were amazing! I had great conversation with all of the staff and they all taught me something I did not know. The brief about the tools beforehand, how to make the trail and use the tools was great...I would love to attend another event when I visit my son in Colorado again! Thank You for a WONDERFUL experience!!
