This morning, I drove to Lander, Wyoming and rode the Bus Loop trail network:

I then headed up Sinks Canyon, where the Popo Agie river goes underground and rises back up 3/4 of a mile away after flowing for roughly 2 hours underground. Heading up-canyon, I visited the “rise” first, where the water comes out of the canyon wall and forms a deep pool where a school of massive trout live:

Next up was the “sink”, where the river flows into its subterranean channel:

At the visitor center, they had this sand pit. A sensor above reads the “terrain” of the sand and projects a real-time colored topographic image onto the sand:

I ended the day dispersed camping up Sinks Canyon in the Shoshone National Forest at 7000-ish feet, at the trailhead for another mountain biking area:

The Middle Popo Agie River is a few steps from the RV:
