Sinks Canyon State Park, State park near Lander, Wyoming.
The Middle Fork Popo Agie River flows through limestone formations, creating a canyon system within the southern Wind River Mountains.
The park received official recognition as a Wyoming State Park in 1971, preserving the geological formations and natural resources for public access.
The Middle Fork Popo Agie River's name comes from the Crow Native American language, reflecting the historical presence of indigenous peoples in this region.
The park maintains four heated yurts with electricity, accommodating between five and ten guests throughout all seasons of the year.
At The Sinks, the river completely disappears into a limestone cavern, resurfacing quarter mile downstream at a pool called The Rise.
