  • Expansion of the permitted 15.7-acre quarry to a 321-acre mine and total permit area of 447 acres.
  • The existing quarry and expansion are on public land.

  • Operations seven days a week, year-round.
  • Development of a wider haul route along Transfer Trail, from the mine to Highway 6.
  • Hauling truckloads of rock from the mine site to Highway 6, up to 450 round trips per day.
  • RMI has yet to inform the public where the mined material is going or how it will be transported through and beyond Glenwood Springs.

The impacts we face

  • A mine scar running 1,800 vertical feet down the mountainside, visible from most of Glenwood Springs.
  • Constant truck traffic between mine and rail yard, one truck each direction every 96 seconds, 6 a.m. to 6 p.m. daily.
  • Noise from rock blasting, crushing, loading and hauling.
  • Potential risk to to the delicate groundwater network feeding the area’s hot springs aquifers.
  • Dust, air pollution and carbon emissions.
  • Consumptive use of water to control dust at the mine.
  • Potential risk of polluted storm runoff or debris flows from the exposed mine area.
  • Obliteration of the recently-discovered Witches’ Pantry Cave and other karst formations.
  • Destruction of habitat for wildlife, including deer, bighorn sheep, bear, mountain lion, bald eagles, hawks, songbirds and bats.

The consequences that threaten us

  • Long-term daily impacts to quality of life for residents and visitors.
  • Acute impacts to vital tourist attractions: Glenwood Caverns Adventure Park, Iron Mountain Hot Springs and Glenwood Hot Springs Lodge & Pool.
  • Disruptions to boating, fishing, activities at Two Rivers Park, and recreation on Transfer Trail.
  • Severe community effects, including truck traffic, dust, noise, light pollution, health risks, and a permanent, unsightly mine scar.
  • Congestion and road damage from heavy truck traffic.
  • Decline in property values, tax revenues and community vitality.
