We lead events in the Front Range and beyond, and sponsor activities to inform Sierra Club members and the general public about local, regional, state, and national environmental issues. Please join us at one of our hikes, meetings, or events!
"Climate change, the trees, streams, and puddles, and birds, bugs, and frogs, attest, is not a matter of opinion or belief. It is an observable fact. Leaves don't lie, frost isn't running for office, frogs don't fund-raise, pollinators don't put out press releases."
