Muddy Ridge is an expanse of undeveloped land in the northeast portion of the Wind River Indian Reservation removed from Tribal control in 1920 to create irrigation infrastructure for non-Tribal residents. GYC is working in lockstep with Tribal leadership from both the Eastern Shoshone and Northern Arapaho Tribes to advocate for the repatriation of Muddy Ridge and resolve this decades-old injustice.

More than 14 Tribal Nations met with a host of federal agencies and non-governmental organizations to bring further discussion to the management of federal lands and how Indigenous values and beliefs can merge into stewardship of lands that were once aboriginal homelands to many Tribes and Bands.
