The Snake River is a major river of the greater Pacific Northwest region in the United States. At 1,078 miles (1,735 km) long, it is the largest tributary of the Columbia River, in turn the largest North American river that empties into the Pacific Ocean. The Snake River rises in western Wyoming, then flows through the Snake River Plain of southern Idaho, the rugged Hells Canyon on the Oregon–Idaho border and the rolling Palouse Hills of Washington, emptying into the Columbia River at the Tri-Cities, Washington.
Shoshone is the county seat and largest city of Lincoln County, Idaho, United States. The population was 1,461 at the 2010 census. In contrast to the Shoshone Native American tribe for which it is named, the city's name is correctly pronounced "Show-shown", with a silent "e".

Craters of the Moon National Monument and Preserve is a U.S. national monument and national preserve in the Snake River Plain in central Idaho. It is along US 20, between the small towns of Arco and Carey, at an average elevation of 5,900 feet (1,800 m) above sea level. The protected area's features are volcanic and represent one of the best-preserved flood basalt areas in the continental United States.
Newberry Volcano is a large active shield volcano located about 20 miles (32 km) south of Bend, Oregon, United States, 35 miles (56 km) east of the major crest of the Cascade Range, within the Newberry National Volcanic Monument. Its highest point is Paulina Peak. The largest volcano in the Cascade Volcanic Arc, Newberry has an area of 1,200 square miles (3,100 km2) when its lava flows are taken into account. From north to south, the volcano has a length of 75 miles (121 km), with a width of 27 miles (43 km) and a total volume of approximately 120 cubic miles (500 km3). It was named for the geologist and surgeon John Strong Newberry, who explored central Oregon for the Pacific Railroad Surveys in 1855. The surrounding area has been inhabited by Native American populations for more than 10,000 years.
Mount McLoughlin is a dormant steep-sided stratovolcano, or composite volcano, in the Cascade Range of southern Oregon and within the Sky Lakes Wilderness. It is one of the volcanic peaks in the Cascade Volcanic Arc, within the High Cascades sector. A prominent landmark for the Rogue River Valley, the mountain is north of Mount Shasta, and Crater Lake lies to the north-northeast. It was named around 1838 after John McLoughlin, a Chief Factor for the Hudson's Bay Company. Mount McLouglin's prominence has made it a landmark to Native American populations for thousands of years.
The Snake River Plain is a geologic feature located primarily within the U.S. state of Idaho. It stretches about 400 miles (640 km) westward from northwest of the state of Wyoming to the Idaho-Oregon border. The plain is a wide, flat bow-shaped depression and covers about a quarter of Idaho. Three major volcanic buttes dot the plain east of Arco, the largest being Big Southern Butte.
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.
Hell's Half Acre Lava Field is a basaltic lava plain located on the Snake River Plain of Idaho in the United States. It is the easternmost of the basaltic lava fields on the Snake River Plain, located about 25 miles (40 km) west of Idaho Falls, Idaho and 30 miles (48 km) north of Pocatello, Idaho. In 1976, the National Park Service designated the northwestern portion of the site a National Natural Landmark. In 1986, the Bureau of Land Management recommended that 68,760 acres (27,830 ha) of the site, located just southeast of the National Natural Landmark, to be a wilderness study area.
The Idaho Transportation Department (ITD) is the state of Idaho governmental organization responsible for state transportation infrastructure. This includes ongoing operations and maintenance as well as planning for future needs of the state and its citizens. The agency is responsible for overseeing the disbursement of federal, state, and grant funding for the transportation programs of the state.
The Fossil Falls is a unique geological feature, located in the Coso Range of California in the United States. Volcanic activity in the mountain range, along with meltwater from glaciers in the nearby Sierra Nevada, played a role in the creation of the falls. They are located near the community of Little Lake, 1.0 mi (1.6 km) off US 395 on Cinder Road to Red Hill, with signs to Fossil Falls.
The Fort Rock-Christmas Lake Valley Basin is the basin of a former inland sea that existed in that region from Pliocene through late Pleistocene time. The Fort Rock basin maar field includes over 30 hydrovolcanic landforms spread over an area of 1,500 square miles (4,000 km2). During the Pleistocene and early Holocene, Paleolake Fort Rock encompassed the entire basin.
The Horse Lava Tube System is a series of lava tubes within Deschutes County, Oregon, of the United States. The system starts within the Deschutes National Forest on the northern flank of Newberry Volcano and heads north into and near the city of Bend. The system continues north to Redmond and includes the Redmond Caves. The flow diverts into the Redmond Dry Canyon, where the last known segment is known to exist; however, the basalt flow that created the system goes beyond to Crooked River Ranch and terminates just short of the Crooked River Gorge. The lava flow that created the Horse system is also referred to as the Horse Cave lobe and it filled the ancient channel of the Deschutes River which at that time flowed around the east side of Pilot Butte. The Horse Cave lobe is a part of the basalt of Lava Top Butte which also consists of the Arnold Lava Tube System, the Badlands rootless shield, and the Lava Top butte basalt. All have a geologic age around 80,000 years old.
Salmon Falls Creek is a tributary of the Snake River, flowing from northern Nevada into Idaho in the United States. Formed in high mountains at the northern edge of the Great Basin, Salmon Falls Creek flows northwards 121 miles (195 km), draining an arid and mountainous basin of 2,103 square miles (5,450 km2). The Salmon Falls Creek valley served as a trade route between the Native American groups of the Snake River Plain and Great Basin. Today, most of its water is used for irrigation.
Idaho Central Credit Union (ICCU) is a state-chartered credit union in the western United States, headquartered in Chubbuck, Idaho, adjacent to Pocatello. ICCU is the largest credit union in Idaho, with numerous branches serving more than 390,000 members and assets of $5 billion; its governing agency is the state's Department of Finance.
Paleontology in Idaho refers to paleontological research occurring within or conducted by people from the U.S. state of Idaho. The fossil record of Idaho spans much of the geologic column from the Precambrian onward. During the Precambrian, bacteria formed stromatolites while worms left behind trace fossils. The state was mostly covered by a shallow sea during the majority of the Paleozoic era. This sea became home to creatures like brachiopods, corals and trilobites. Idaho continued to be a largely marine environment through the Triassic and Jurassic periods of the Mesozoic era, when brachiopods, bryozoans, corals, ichthyosaurs and sharks inhabited the local waters. The eastern part of the state was dry land during the ensuing Cretaceous period when dinosaurs roamed the area and trees grew which would later form petrified wood.
Hager Mountain is a volcanic peak in Oregon in the northwest corner of the Basin and Range Province in the United States. The mountain is located south of the small unincorporated community of Silver Lake in south-central Oregon, and it is in the Fremont–Winema National Forest. On the summit, there is a fire lookout operated during the summer and fall by the United States Forest Service. There are several hiking trails that lead to the lookout station.
Black Magic Canyon is a small canyon located north of Shoshone, Idaho along Idaho State Highway 75. It was created by the Big Wood River over the last 10,000 years. The river carved this canyon through 800,000-year-old basalt lava flows leaving sculpted black rock reminiscent of Utah's slot canyons. Because of irrigation use during the summer and snowfall in winter, the canyon is best explored in spring or fall.
The Guffey Butte–Black Butte Archeological District is a 14,000 acres (57 km2) historic district in southwestern Idaho, United States, that is listed on the National Register of Historic Places (NRHP). It includes numerous archeological sites in Ada, Canyon, Elmore, and Owyhee counties.
The Shale Butte Wilderness Study Area is a Bureau of Land Management wilderness study area (WSA) in Lincoln County, Idaho. It covers 15,560 acres (6,300 ha). The WSA is located to the south of Craters of the Moon National Monument and Preserve.
