Colleen Cooley grew up in Shą́ą́ʼtóhí, a small community located on the Navajo Nation in northeast Arizona. She guides on the San Juan and Green Rivers and advocates for the landscapes, waters, and cultures that surround her. Here, we speak with her about her experience as a Diné river guide, the importance of water, and what she wants to see moving forward for Native and Indigenous guides and Native communities in the region.
