Geyser Basin
Take one of the short loop trails giving visitors a good chance of seeing a variety of geysers, from the ever-entertaining Anemone with its short intervals of 5-10 minutes to the impressive Beehive with its unpredictable eruptions reaching 100-150 feet! Numerous other combination loops or one-way walks can be chosen in the Upper Geyser Basin. Features such as Castle, Grand, Riverside, and Daisy geysers along with Morning Glory Pool are easily accessed using the Old Faithful self-guiding trail map. Details on geyser prediction times may be obtained by stopping by the visitor center.
The Upper and Lower Falls of the Yellowstone
The falls are erosional features formed by the Yellowstone River as it flows over progressively softer, less resistant rock. The Upper Falls is upstream of the Lower Falls and is 109 ft. high. It can be seen from the Brink of the Upper Falls Trail and from Uncle Tom's Trail.
Mt. Washburn
Mt. Washburn is the main peak in the Washburn Range, rising 10,243 ft. above the west side of the canyon. It is the remnant of volcanic activity that took place long before the formation of the present canyon. It is an excellent example of subalpine habitat and is very accessible to the average visitor. Bighorn sheep and an abundance of wildflowers can be found on its slopes in the summer.
Hayden Valley
Hayden Valley is one of the best places in the park to view a wide variety of wildlife. It is an excellent place to look for grizzly bears, particularly in the spring and early summer when they may be preying upon newborn bison and elk calves. Large herds of bison may be viewed in the spring, early summer, and during the fall rut, which usually begins late July to early August.
Yellowstone Lake
With a surface area of 132 square miles, Yellowstone Lake is the largest lake at high elevation (i.e., more than 7,000 ft.) in North America. It is a natural lake, situated at 7,733 ft. above sea level. It is roughly 20 miles long and 14 miles wide with 141 miles of shoreline.
