Stop the Transfer Trail Mine Expansion


Rocky Mountain Resources (RMR) is proposing a massive expansion to the Transfer Trail limestone and gravel mine they operate just outside of Glenwood Springs (on public land). RMR wants to extract FIVE MILLION tons of material annually and operate 24/7, 365 days per year. They believe operations will last for a minimum of 20 years. Extraction, crushing and hauling are proposed from 6 am to 6 pm with blasting from 9 am to 4 pm. To achieve their five million ton/year goal, they’ll need to average 38,000 lbs./minute during each twelve hour production shift. RMR would like to increase their permitted size from 15.7 acres to 440 acres with 320 acres of “disturbed area”. The proposed operation will start stripping material at 8,400 ft. and eventually end up at 6,600 ft. in the existing quarry. When complete, the stripped 1,800 vertical foot mountain face will be visible from a majority of town. RMR is proposing to increase their truck haul traffic from 20 trucks/day to between 320 and 450 trucks/day. The truck loads will fill a waiting 100 ton railcar every 5.25 minutes in the railyard along the Colorado River. The loading area is directly across from Iron Mtn. Hot Springs, near Two Rivers Park and less than a mile from the heart of downtown Glenwood. This proposed operation will have significant impacts to the City of Glenwood Springs, the Roaring Fork Valley and beyond.

The Glenwood Springs Citizens’ Alliance encourages you to help STOP THE TRANSFER TRAIL MINE EXPANSION.

Tourism is Glenwood Springs’ Economic Driver.

Glenwood Springs has been a popular tourist destination since 1885.  The Glenwood Hot Springs was completed in 1888 followed by the opening of the Hotel Colorado in 1893.  At no time in history has Glenwood Springs been a “mining town.” Learn more.

The mine expansion will create a wound that will never heal.

Rocky Mountain Resources expansion of the mine operation on Transfer Trail will leave a scar on a mountain visible from almost everywhere around Glenwood Springs. (Green shows visibility of mine scar. Red is the mine.) Learn more.
