Important Community Update


We previously shared with you the news that the Colorado Mountain Club and several of our employees were among victims of a criminal predator, who was arrested earlier this year and is facing multiple charges of placing hidden cameras in our office and throughout the Denver Metro area and violating individual privacy. We are appalled and angered by this terrible violation and its impact on our team, and we continue to work with authorities to support the case against him. We have been told by authorities conducting the investigation that all victims at CMC have been notified.

The perpetrator, now charged with several criminal offenses, is a former employee who was terminated in November 2019 after our investigation substantiated a complaint of bullying and harassment against a co-worker. At that time, there were no indications that any criminal behavior had taken place or that there were any safety concerns from our staff. It was not until January 2021 that we were alerted by police of suspected criminal activity involving hidden devices and privacy violations in our workplace. 

The safety and wellbeing of our staff, volunteers, and members is always our foremost priority. We immediately shared the information with staff and CMC members and quickly began our own assessment and action plan to support and protect our team.

Statement Against Racism & Hate

Statement Against Racism and Hate in the Outdoors


Colorado Mountain Club explicitly condemns racism, hate, and all systems and behavior that erode the safety of the Black Community, Indigenous Peoples, and other Communities of Color.

Incidences of hate and racism in the outdoors are not isolated to Ahmaud Arbery running in Georgia or Christian Cooper birding in New York City’s Central Park. All over the country––including right here in Colorado––people of color disproportionately face suspicion, unprovoked confrontations, and other dangers in the outdoors solely because of the color of their skin.

We must educate ourselves & our community, and work to ensure that the Black Community, Indigenous Community, & other Communities of Color have equitable access to, and feel safe and welcome recreating in Colorado's outdoors.
