Iguazú Falls or Iguaçu Falls are waterfalls of the Iguazu River on the border of the Argentine province of Misiones and the Brazilian state of Paraná. Together, they make up the largest waterfall system in the world. The falls divide the river into the upper and lower Iguazu. The Iguazu River rises near the heart of the city of Curitiba. For most of its course, the river flows through Brazil; however, most of the falls are on the Argentine side. Below its confluence with the San Antonio River, the Iguazu River forms the border between Argentina and Brazil.
The geothermal areas of Yellowstone include several geyser basins in Yellowstone National Park as well as other geothermal features such as hot springs, mud pots, and fumaroles. The number of thermal features in Yellowstone is estimated at 10,000. A study that was completed in 2011 found that a total of 1,283 geysers have erupted in Yellowstone, 465 of which are active during an average year. These are distributed among nine geyser basins, with a few geysers found in smaller thermal areas throughout the Park. The number of geysers in each geyser basin are as follows: Upper Geyser Basin (410), Midway Geyser Basin (59), Lower Geyser Basin (283), Norris Geyser Basin (193), West Thumb Geyser Basin (84), Gibbon Geyser Basin (24), Lone Star Geyser Basin (21), Shoshone Geyser Basin (107), Heart Lake Geyser Basin (69), other areas (33). Although famous large geysers like Old Faithful are part of the total, most of Yellowstone's geysers are small, erupting to only a foot or two. The hydrothermal system that supplies the geysers with hot water sits within an ancient active caldera. Many of the thermal features in Yellowstone build up sinter, geyserite, or travertine deposits around and within them.
The Grand Canyon of the Yellowstone is the first large canyon on the Yellowstone River downstream from Yellowstone Falls in Yellowstone National Park in Wyoming. The canyon is approximately 24 miles (39 km) long, between 800 and 1,200 ft deep and from .25 to .75 mi wide.
Grand Coulee is an ancient river bed in the U.S. state of Washington. This National Natural Landmark stretches for about 60 miles (100 km) southwest from Grand Coulee Dam to Soap Lake, being bisected by Dry Falls into the Upper and Lower Grand Coulee.
Shoshone Falls is a waterfall in the western United States, on the Snake River in south-central Idaho, approximately three miles (5 km) northeast of the city of Twin Falls. Sometimes called the "Niagara of the West," Shoshone Falls is 212 feet (65 m) in height, 45 feet (14 m) higher than Niagara Falls, and flows over a rim nearly one thousand feet (300 m) in width.
The Cook–Folsom–Peterson Expedition of 1869 was the first organized expedition to explore the region that became Yellowstone National Park. The privately financed expedition was carried out by David E. Folsom, Charles W. Cook and William Peterson of Diamond City, Montana, a gold camp in the Confederate Gulch area of the Big Belt Mountains east of Helena, Montana. The journals kept by Cook and Folsom, as well as their personal accounts to friends were of significant inspirational value to spur the organization of the Washburn-Langford-Doane Expedition which visited Yellowstone in 1870.
The Washburn Expedition of 1870 explored the region of northwestern Wyoming that two years later became Yellowstone National Park. Led by Henry D. Washburn and Nathaniel P. Langford, and with a U.S. Army escort headed by Lt. Gustavus C. Doane, the expedition followed the general course of the Cook–Folsom–Peterson Expedition made the previous year.
Tower Fall is a waterfall on Tower Creek in the northeastern region of Yellowstone National Park, in the U.S. state of Wyoming. Approximately 1,000 yards (910 m) upstream from the creek's confluence with the Yellowstone River, the fall plunges 132 feet (40 m). Its name comes from the rock pinnacles at the top of the fall. Tower Creek and Tower Fall are located approximately three miles south of Roosevelt Junction on the Tower-Canyon road.
The Grand Loop Road is a historic district which encompasses the primary road system in Yellowstone National Park. Much of the 140-mile (230 km) system was originally planned by Captain Hiram M. Chittenden of the US Army Corps of Engineers in the early days of the park, when it was under military administration. The Grand Loop Road provides access to the major features of the park, including the Upper, Midway and Lower geyser basins, Mammoth Hot Springs, Tower Fall, the Grand Canyon of the Yellowstone and Yellowstone Lake.
The Gardner River is a tributary of the Yellowstone River, approximately 25 miles (40 km) long, in northwestern Wyoming and south central Montana in the United States. The entire river is located within Yellowstone National Park. It rises on the slope of Joseph Peak, Gallatin Range in the northwestern part of the park, and winds southeast through Gardner's Hole, a broad subalpine basin which is a popular trout fishing location. The Gardner falls within the Native Trout Conservation Area and anglers are allowed to take an unlimited number of brown and rainbow trout. Mountain whitefish and Yellowstone cutthroat trout must be released. Angling on the Gardner is governed by Yellowstone National Park fishing regulations. After merging with Panther Creek, Indian Creek and Obsidian Creek, it then turns north and flows through a steep canyon where it cuts through a basaltic flow from approximately 500,000 years ago known as Sheepeater Cliffs. Below Sheepeater, Glen Creek out of Golden Gate Canyon and Lava Creek out of Lava Creek Canyon join the Gardner near Mammoth Hot Springs. The river crosses the 45th parallel in Gardner Canyon and is also home to a popular hot spring known as The Boiling River. The river continues north through Gardner Canyon and empties into the Yellowstone near Gardiner, Montana.
The following articles relate to the history, geography, geology, flora, fauna, structures and recreation in Yellowstone National Park.
Firehole Falls is a waterfall on the Firehole River in southwestern Yellowstone National Park in the United States. The falls are located approximately 0.5 miles (0.80 km) upstream from the confluence of the Firehole and Gibbon Rivers at Madison Junction. Firehole Falls has a drop of approximately 40 feet (12 m). The falls are located within Firehole Canyon on Firehole Canyon Drive, a one-way road that parallels the main Madison Junction to Old Faithful road.
Salt Creek Falls is a cascade and plunge waterfall on Salt Creek, a tributary of the Middle Fork Willamette River, that plunges into a gaping canyon in the Willamette National Forest near Willamette Pass in Lane County, Oregon. The waterfall is notable for its main drop of 286 feet (87 m), ranking third highest among plunge waterfalls in Oregon, after Multnomah Falls and Watson Falls.) The pool at the bottom of Salt Creek Falls waterfall is 66 feet (20 m) deep.
The Bechler River is a remote major river flowing southwest entirely within the confines of Yellowstone National Park to its confluence with the Fall River in the southwest section of the park. The river was named by Frank Bradley, a member of the 1872 Hayden Geological Survey for cartographer and explorer Gustavus R. Bechler, the chief surveyor and mapmaker on the survey. Henry Gannett also a member of the survey claimed that Bechler discovered the river, but trapper Osborne Russell explored the area in 1830.
Fall River rises on the Madison and Pitchstone Plateaus in the southwest corner of Yellowstone National Park, Wyoming and flows approximately 64 miles (103 km) to its confluence with the Henrys Fork of the Snake River near Ashton, Idaho. Historically, the river was referred to as the Middle Fork of the Snake River or as Fall River or the Falls River by trappers and prospectors as early as the 1830s. It was officially named the Falls River by 1872 Hayden Geological Survey, but was always called Fall River by the locals and so the U.S. Board on Geographic Names changed the official name to Fall River in 1997 at the request of Idaho authorities. The river is home to numerous waterfalls and cascades in its upper reaches.
There are nine named plateaus in Yellowstone National Park. These plateaus are part of the much larger Yellowstone Plateau and dominate areas in the park south and west of the Gallatin and Absaroka mountain ranges. Four of the plateaus are from rhyolite lava flows that occurred between 110,000 and 70,000 years ago.
Silver Cord Cascade is a horsetail type waterfall on Surface Creek, a tributary of the Yellowstone River in Yellowstone National Park. Surface Creek flows out of Ribbon Lake off the South rim of the Grand Canyon of the Yellowstone and plunges 1,200 feet (370 m) to the Yellowstone River. It is considered the tallest waterfall in Yellowstone.
Proxy Falls, also known as Lower Proxy Falls, is a cascade and plunge waterfall from a collection of springs on the shoulder of North Sister, that plunges into a gaping canyon near McKenzie Pass in the Willamette National Forest, near Belknap Springs, Oregon. The waterfall is notable for its main drop of 226 feet (69 m) which makes it one of the highest plunge waterfalls in Oregon.
