Old Faithful is a cone geyser located in Yellowstone National Park in Wyoming, United States. Old Faithful was named in 1870 during the Washburn-Langford-Doane Expedition and was the first geyser in the park to receive a name. It is a highly predictable geothermal feature; since 2000, it has erupted every 44 to 125 minutes.The geyser, as well as the nearby Old Faithful Inn, is part of the Old Faithful Historic District.

Yellowstone Falls consist of two major waterfalls on the Yellowstone River, within Yellowstone National Park, Wyoming, United States. As the Yellowstone river flows north from Yellowstone Lake, it leaves the Hayden Valley and plunges first over Upper Yellowstone Falls and then a quarter mile (400 m) downstream over Lower Yellowstone Falls, at which point it then enters the Grand Canyon of the Yellowstone, which is up to 1,000 feet (304 m) deep. Cascading from the 590,000 year old Canyon Rhyolite lava flow, Lower Yellowstone Falls is the largest volume waterfall in the Rocky Mountains of the United States.These falls (44°43′05″N 110°29′46″W) are 308 feet (94 m) high, or nearly twice as high as Niagara Falls. The volume of water flowing over Lower Yellowstone Falls can vary from 680 cu ft/s (19 m3/s) in the autumn, to 8,400 cu ft/s (240 m3/s) at peak runoff in late springtime.[citation needed] The flow rate of Lower Yellowstone Falls is much less than that of Niagara Falls, as the Yellowstone River is only 70 feet (21 m) at the point at which it goes over the lower falls, whereas the Niagara River is 2,600 feet (790 m) in width as it approaches the crest line of Horseshoe Falls.

Jenny Lake is located in Grand Teton National Park in the U.S. state of Wyoming. The lake was formed approximately 12,000 years ago by glaciers pushing rock debris which carved Cascade Canyon during the last glacial maximum, forming a terminal moraine which now impounds the lake. The lake is estimated to be 423 feet (129 m) deep and encompasses 1,191 acres (482 ha). Jenny Lake is considered to be a major focal point in Grand Teton National Park, with many hiking trails, scenic boat rides, and quick access to the major climbing routes onto the tallest peaks of the Teton Range.

Grand Teton is the highest mountain in Grand Teton National Park, in Northwest Wyoming, and a classic destination in American mountaineering. Grand Teton, at 13,775 feet (4,199 m), is the highest point of the Teton Range, and the second highest peak in the U.S. state of Wyoming after Gannett Peak. The mountain is entirely within the Snake River drainage basin, which it feeds by several local creeks and glaciers.The Teton Range is a subrange of the Rocky Mountains, which extend from southern Alaska to northern New Mexico.
