The agricultural open space and recreational opportunities in and around Hygiene and Lyons are cherished by many, but may soon be dramatically affected by an intensive surface mining operation, possibly lasting until 2033. A Special Use permit issued two decades ago would allow open pit mining in the geologically unique St. Vrain Valley, with the total area of the use approved at approximately 881 acres. Residents and visitors to the area would experience potentially serious health effects; the compromised availability and quality of water; environmental issues affecting wildlife and habitat; and community impacts such as traffic congestion from trucks and trains, as well as noise and light pollution.
Save Our St. Vrain Valley (SOSvv) is a community of concerned citizens. WE NEED YOUR HELP. Please join us if you are:
- A resident of Hygiene, Longmont, Lyons, or the vicinity

- A cyclist, runner, equestrian, birdwatcher, sportsman, or photographer
- A farmer, rancher, gardener, or beekeeper
- An ally for the environmental protection of Colorado’s Front Range
