The Colorado Mountain Club's Recreation Impact Monitoring System (CMC RIMS) is the place where grass roots citizen scientists capture observable data to help public land managers monitor trails, campsites and natural resources. CMC RIMS gives you the opportunity to collect data in a structured, assessment format and provide detailed information for Federal, State, and local land management organizations. CMC RIMS is your advocacy and conservation tool to help steward our public lands - improving recreational experiences and preserving natural resources for future generations. CMC RIMS supports individual user and organizational data capture and use goals. For organizations that are interested in setting up data collection and use plans, contact CMC at

CMC RIMS free features include:

• Map based interface with online & offline GPS locating
• Search for Trailheads, Water Access & Campsites near you
• "Check-In" to record your current recreation activity and assist with visitor use monitoring
• Upload images
In addition to the free features, CMC RIMS volunteer "monitoring" features include adding data to assess and inventory:
• Trails
• Campsites
• Water access points
• Signs and facilities
• Visitor use

CMC provides training on how to complete assessments. Upon completion of this training, volunteers will be dubbed as trained citizen scientists and provided access to monitoring features within the app. For more information on volunteering and training, contact CMC at
