Sinks Canyon State Park

Sinks Canyon is so named because of the Middle Fork of the PopoAgie (pronounced popo Shuh), a rushing mountain river that flows out of the Wind River Mountains and through the canyon. Halfway down the canyon, the river abruptly turns into a large limestone cavern, and the crashing water "sinks" into fissures and cracks at the back of the cave. The river is underground for no one knows how far until it appears 2 hours later 1/4 mile downstream from the cave it entered into an area called " The Rise". The rise is a calm small pool containing 12-15 lb. trout. You can't fish there as it is a state park and the fish are protected. The river then continues down to the valley below.
