Protecting the slopes of Colorado’s Mount Champion
May 15, 2026-
The Trust recently completed the transfer of 194 acres on the slopes of Mount Champion, just outside the Mount Massive Wilderness, to the San Isabel National Forest in Colorado.
The Champion Mine South property, which stretches from the North Fork of Lake Creek almost to the summit of Mount Champion, includes remnants of the Champion Mine which was active from 1907-1940 mining gold, silver, copper, and lead. The property is being transferred to public ownership in two phases— this first 194-acre phase, and a second 40-acre phase that will follow at a later date.
Along with the remnants of Champion Mine, a mill site where ore was processed was also located on the 40-acre portion of the property that will transfer later. The 50-ton mill used mercury to dissolve gold from ore that was pulled from the mine and crushed, resulting in a denser material that could more easily be separated from the remaining ore. It was then heated to distill off the mercury for reuse, leaving behind gold particles. This process commonly resulted in waste tailings contaminated with heavy metals.
Last year the Trust completed extensive environmental testing for mercury and other heavy metals on the property in partnership with the EPA-led Mixed Ownership Group, which consists of federal and state agencies, local governments, and non-governmental organizations focused on completing assessments and remedial actions on abandoned mine lands throughout Colorado. The testing all came back within safe levels, an important step to ensure the property is wilderness-ready before becoming public lands. With this due diligence completed, the second phase of the transfer is moving forward.

The property was generously donated to the Trust in 2023 by local landowner Amy Margerum Berg: “My late husband, Charles “Chuck” McLean, had the foresight to purchase these mining claims with the intent of protecting them from development. My son, Slater McLean, and I are so proud to be donating this land in his honor. He loved this land more than anything and spent hours exploring and hiking every inch of this spectacular backcountry wilderness. He would be very happy to know that the land will now be protected forever.”
The popular North Fork Lake Creek Trail leads hikers, backpackers, and horsemen into the 30,000-acre Mount Massive Wilderness and runs through the base of the Champion Mine South property. Protecting the property under public ownership ensures public access on the trail and mitigates the management and liability concerns that have recently cut off access to several of Colorado’s 14ers. The project also protects important wildlife habitat, spanning from streamside riparian zones to alpine meadows above treeline, and is home to bighorn sheep.
