Yellowstone - Yellowstone River

Emerging from Yellowstone Lake, the Yellowstone River flows through a quiet valley, with bison grazing on the meadows; then, to the north of Hayden Valley, it plunges over two spectacular waterfalls into a wild and romantic canyon.

There is a fascinating walk along the river that introduces visitors to the geology of the region, passing old lava flows and less well known zones of geothermal activity.
