Yellowstone - Yellowstone River

In Hayden Valley, a western side valley of almost genial aspect, a variety of wild life can be observed, including bison, deer and sometimes grizzly bears.

A few miles below Fishing Bridge are the striking mud volcanoes of the Mud Volcano Area and the simmering Sulphur Caldron. Visitors must take care to stay on the boardwalks.

The easily accessible Upper Falls on the Yellowstone River drop 110 ft. A few hundred yards lower down the river plunges 310 ft into a gorge with a deafening roar. As a result of chemical reactions in the rhyolite which outcrops here the walls of the gorge shimmer in reddish to yellow tones. There are very fine views of the falls from Lookout Point and Grandview Point on the north side of the valley, near the holiday settlement of Canyon Village.
