Land Acknowledgement

Eco-Cycle operates on the ancestral homelands and unceded territory of Indigenous Peoples who have stewarded this land since time immemorial. We acknowledge the Di De’i (Apache), Hinono’eiteen (Arapaho), Tsétsėhéstȧhese (Cheyenne), Nʉmʉnʉʉ (Comanche), Caiugu (Kiowa), Čariks i Čariks (Pawnee), Sosonih (Shoshone), Oc’eti S’akowin (Sioux), and Núuchiu (Ute)—nations with deep historical ties to this region.

We honor their enduring presence, resilience, and contributions to the land, waters, and ecosystems of Boulder. We recognize that the displacement and oppression of Indigenous Peoples are not relics of the past but ongoing injustices that demand our attention and action.
