Help Glenwood Springs prevent future mining at the Transfer Trail limestone quarry
The Glenwood Springs area community and those who visit stand together to oppose future mining at the Transfer Trail limestone quarry.
Rocky Mountain Industrials (RMI) stopped mining operations at the quarry in December 2024.
The company is pursuing a new mining permit and a mine expansion.
Many issues remain unresolved:

Quarry site reclamation process and funding
The Colorado Division of Reclamation, Mining & Safety is the lead agency to oversee reclamation of the site. The state holds a surety bond of $489,758. It is seeking a bond of $3.2 million.

RMI’s future plans for its massive limestone mine
Rocky Mountain Industrials still holds 44 unpatented mining claims under the existing quarry and running up the mountainside. It may attempt to revive its 2019 proposal to expand the quarry.

Permanent protection to prevent more mining
The mine expansion poses unacceptable threats to the Glenwood Springs community. Because we value the environment and our quality of life, our aim is to stop the mine expansion for good.
The quarry is on federal public lands
The quarry site and RMI’s mining claims are on public lands managed by the U.S. Bureau of Land Management (BLM).
These are OUR public lands. We have a say in what happens!
The Glenwood Springs community is united in opposition.
Please join us in this cause to protect our community, our economy and our environment.
