Mount St. Helens: No place for a mine

The Green River Valley lies at the doorstep of Mount St. Helens (Lawetlat’la). It is no place for a mine. Cascade Forest Conservancy has been fighting proposals to construct a dangerous open-pit mine in this unique corner of the Cascades for more than 15 years.

A mine could devastate an area important to many Tribes, local communities, and people who value outdoor recreation. The mine would replace a place loved by hunters, anglers, hikers, cyclists, backcountry horseback riders, and others, with a permanent scar on the landscape.

Impacts from the mine would threaten forest health, local biodiversity, fish populations, and even the human communities living near the Green, North Fork Toutle, and Cowlitz Rivers.

We have successfully challenged prospecting permits multiple times in Federal court, but after each victory, the mining corporation has tried again. 

We won’t be able to hold them off in court forever. That is why CFC founded the Green River Valley Alliance campaign–a new coalition working towards a solution that can end the threat of a mine here once and for all. Join us today!


Cascade Forest Conservancy is involved in a lawsuit to protect the the Pumice Plain created in the aftermath of the famous 1980 eruption of Mount St. Helens (Lawetlat’la). Essentially baked clean by a blanket of superheated rock and ash, the Pumice Plain provides scientists and researchers an unprecedented chance to study ecosystem formation after a cataclysmic event. Congress protected this landscape and the work being done by designating the area a Class I Research Area within the Mount St. Helens National Volcanic Monument. Life here is bouncing back far faster than expected, and important discoveries are still being made.  

For 40 years, the Pumice Plain has remained a pristine roadless area. In addition to its value as a research site, it provides visitors from around the world a unique opportunity to see the power of a Cascade volcano and the stubborn resilience of life up close.

This place and the scientific opportunity it holds are now being imperiled by a US Forest Service plan to build a road through the heart of this landscape. The plan is a threat to research, fragile habitats, newly forming watersheds, and the public’s right to this place for themselves.

The Instream Wood Bank Network

A combination of factors like streamside logging have left many waterways unnaturally free of fallen logs and woody debris. Many species, including salmon, trout, and others, need the deep cool pools and habitat diversity downed wood in waterways create.    

The Instream Wood Bank Network was designed to address two challenges faced by restoration professionals throughout the West; the lack of wood and streams and the difficulty of sourcing the wood needed for restoration efforts. The network sources non-salable wood, then employs local contractors to move wood to a series of wood banks that are set up across the region. These banks then provide logs to restoration groups throughout southwest Washington.

The network also advances restoration in new areas by helping to prioritize, design, and coordinate the installation of wood structures in critical habitat areas. 

The Climate Resilience Guidebook

In 2017, we published the Climate Resilience Guidebook—a detailed look at the ways climate change is likely to impact the unique species, watersheds, and ecosystems of the southern Washington Cascades at the local level. The guidebook also suggests location-specific strategies and restoration priorities designed to preserve biodiversity and rebuild ecosystems to ensure our region is made as resilient as possible to the accelerating impacts of climate change.

An updated and expanded version of the Climate Resilience Guidebook will be released in 2022.

News & updates

Mining reform is currently a hot topic, particularly in Washington D.C. There is a growing national conversation about how best to obtain critical minerals needed to fuel the green energy transition while protecting the environment and communities. There are major challenges that we must address to do so. The laws currently governing mining on federal...
President Biden’s Earth Day Executive Order has real potential to be the start of an important shift in the way forests on federal lands (and beyond) are managed. In the fact sheet provided by the Administration, concerns about climate are front and center. The Order recognizes that forests serve vital functions helping to slow the...
The laws and guidelines regulating the way public lands are managed have come a long way, but the challenges we face today require an updated approach.  The Northwest Forest Plan (NWFP) was implemented almost thirty years ago. The plan–a series of federal policies and guidelines governing land uses within federally managed areas of the Pacific...
Once again, the Cascade Forest Conservancy (CFC) has successfully fought off a corporation’s attempt to develop a new open-pit hard rock mine in the Green River Valley, located at the doorstep of the Mount St. Helens National Volcanic Monument. In February, a US District Court reversed decisions made by the Bureau of Land Management (BLM)...
COURT VACATES DECISIONS BY FEDERAL AGENCIES THAT WOULD HAVE ENABLED MINING EXPLORATION NEAR MOUNT ST. HELENS NEWS RELEASE | February 4, 2022 Portland, OR – On Monday, a US District Court, in Portland, vacated agency decisions by the Bureau of Land Management (BLM) and the United States Forest Service (USFS) which had authorized mining exploration...
