A stratovolcano, also known as a composite volcano, is a typically conical volcano built up by many alternating layers (strata) of hardened lava and tephra. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and explosive eruptions. Some have collapsed summit craters called calderas. The lava flowing from stratovolcanoes typically cools and solidifies before spreading far, due to high viscosity. The magma forming this lava is often felsic, having high to intermediate levels of silica (as in rhyolite, dacite, or andesite), with lesser amounts of less viscous mafic magma. Extensive felsic lava flows are uncommon, but can travel as far as 8 kilometres (5 miles).

The term composite volcano is used because strata are usually mixed and uneven instead of neat layers. They are among the most common types of volcanoes; more than 700 stratovolcanoes have erupted lava during the Holocene Epoch (the last 11,700 years), and many older, now extinct, stratovolcanoes erupted lava as far back as Archean times. Stratovolcanoes are typically found in subduction zones but they also occur in other geological settings. Two examples of stratovolcanoes famous for catastrophic eruptions are Krakatoa in Indonesia (which erupted in 1883 claiming 36,000 lives) and Mount Vesuvius in Italy (which erupted in 79 A.D killing an estimated 2,000 people). In modern times, Mount St. Helens (1980) in Washington State, US, and Mount Pinatubo (1991) in the Philippines have erupted catastrophically, but with fewer deaths.

Flora is an unincorporated community in Wallowa County, Oregon, United States. It is located about 35 miles north of Enterprise, just off Oregon Route 3, and is considered a ghost town. Its elevation is 4350 ft. The community includes 6 mines.

Herbert Clark Hoover (August 10, 1874 – October 20, 1964) was the 31st president of the United States, serving from 1929 to 1933. A wealthy mining engineer before his presidency, Hoover led the wartime Commission for Relief in Belgium and was the director of the U.S. Food Administration, followed by post-war relief of Europe. As a member of the Republican Party, he served as the third United States secretary of commerce from 1921 to 1928 before being elected president in 1928. His presidency was dominated by the Great Depression, and his policies and methods to combat it were seen as lackluster. Amid his unpopularity, he decisively lost reelection to Franklin D. Roosevelt in 1932.

Born to a Quaker family in West Branch, Iowa, Hoover grew up in Oregon. He was one of the first graduates of the new Stanford University in 1895. Hoover took a position with a London-based mining company working in Australia and China. He rapidly became a wealthy mining engineer. In 1914, the outbreak of World War I, he organized and headed the Commission for Relief in Belgium, an international relief organization that provided food to occupied Belgium. When the U.S. entered the war in 1917, President Woodrow Wilson appointed Hoover to lead the Food Administration. He became famous as his country's "food dictator". After the war, Hoover led the American Relief Administration, which provided food to the starving millions in Central and Eastern Europe, especially Russia. His wartime service made him a favorite of many progressives, and he unsuccessfully sought the Republican nomination in the 1920 United States presidential election.

California (/ˌkælɪˈfɔːrniə/) is a state in the Western United States that lies on the Pacific Coast. It borders Oregon to the north, Nevada and Arizona to the east, and shares an international border with the Mexican state of Baja California to the south. With almost 40 million residents across an area of 163,696 square miles (423,970 km), it is the largest state by population, third-largest state by area and the largest state economy in the U.S., with a GDP of approximately $4.1 trillion.

Prior to European colonization, California was one of the most culturally and linguistically diverse areas in pre-Columbian North America. European exploration in the 16th and 17th centuries led to the colonization by the Spanish Empire. The area became a part of Mexico in 1821, as a result of its successful war for independence. Following the U.S. conquest of California, part of the Mexican-American War, California was ceded to the United States in 1848. The California gold rush started in 1848 and led to social and demographic changes, including the California genocide. It organized itself and was admitted as the 31st state in 1850 as a free state, following the Compromise of 1850.

In the United States, aspiring lawyers must normally pass a bar examination before they can be admitted to the bar and become licensed to practice law. Bar exams are administered by states or territories, usually by agencies under the authority of state supreme courts. Almost all states use some examination components created by the National Conference of Bar Examiners (NCBE). Forty-one jurisdictions have adopted the Uniform Bar Examination (UBE), which is composed entirely of NCBE-created components.

In every U.S. jurisdiction except Wisconsin, Oregon, and Washington, all those seeking admission to the bar must pass a bar examination. In Wisconsin, graduates of the Juris Doctor degree programs of the state's two American Bar Association-accredited law schools—the University of Wisconsin Law School and Marquette University Law School—may be admitted to the Wisconsin bar by diploma privilege without taking a bar examination. Oregon permits students who have completed a Juris Doctor program with certain required coursework to obtain bar admission through a Supervised Practice Portfolio Examination. In Washington, the State Supreme Court in March 2024 approved "in concept" alternative pathways based on apprenticeship or work experience.

Nevada (/nəˈvædə/ nə-VAD-ə; Spanish: [neˈβaða] ) is a landlocked state in the Western United States. It is also sometimes placed in the Mountain West and Southwestern United States. It borders Oregon to the northwest, Idaho to the northeast, California to the west, Arizona to the southeast, and Utah to the east. Nevada is the seventh-most extensive, the 32nd-most populous, and the ninth-least densely populated U.S. state. Nearly three-quarters of Nevada's population live in Clark County, which contains the Las Vegas–Paradise metropolitan area, including three of the state's four largest incorporated cities. Nevada's capital is Carson City. Las Vegas is the largest city in the state. Nevada is the westernmost U.S. state without coastline and also the westernmost landlocked first-level country subdivison in the Americas.

Nevada is officially known as the "Silver State" because of the importance of silver to its history and economy. It is also known as the "Battle Born State" because it achieved statehood during the Civil War (the words "Battle Born" also appear on its state flag); due to the presidency of Abraham Lincoln, the Union benefited immensely from the support of newly awarded statehood by the infusion of the monetary support of nearly $400 million in silver ore generated at the time by the Comstock Lode. It is also known as the "Sagebrush State", for the native plant of the same name; and as the "Sage-hen State". The state's name means "snowy" in Spanish, referring to Nevada's extensive number of mountain ranges capped with snow in winter, which help make Nevada among the highest US states by mean altitude. These include the Carson Range portion of the Sierra Nevada (and about 1/3 of Lake Tahoe by surface area), as well as the Toiyabe Range, Ruby Mountains, and Spring Mountains (which exemplify the sky islands of the Great Basin montane forests), in western, central, northeastern, and southern Nevada, respectively. Nevada is the driest U.S. state, both lying in the rain shadow of the Sierra Nevada and receiving among the highest solar irradiance of any U.S. state, and is thus largely desert and semi-arid. Nevada comprises the majority of the Great Basin, as well as a large portion of the Mojave Desert. In 2020, 80.1% of the state's land was managed by various jurisdictions of the U.S. federal government, both civilian and military.

The Great Basin is the largest area of contiguous endorheic watersheds, those with no outlets to the ocean, in North America. It spans nearly all of Nevada, much of Utah, and portions of California, Idaho, Oregon, Wyoming, and Baja California. It is noted for both its arid climate and the basin and range topography that varies from the North American low point at Badwater Basin in Death Valley to the highest point of the contiguous United States, less than 100 miles (160 km) away at the summit of Mount Whitney. The region spans several physiographic divisions, biomes, ecoregions, and deserts.

Lake Tahoe (/ˈtɑːhoʊ/) is a freshwater lake in the Sierra Nevada of the Western United States, straddling the border between California and Nevada. Lying at 6,225 ft (1,897 m) above sea level, Lake Tahoe is the largest alpine lake in North America, and at 122,160,280 acre⋅ft (150.7 km) it trails only the five Great Lakes as the largest by volume in the United States. Its depth is 1,645 ft (501 m), making it the second deepest in the United States after Crater Lake in Oregon (1,949 ft or 594 m).

The lake was formed about two million years ago as part of the Lake Tahoe Basin, and its modern extent was shaped during the ice ages. It is known for the clarity of its water and the panorama of surrounding mountains on all sides. The area surrounding the lake is also referred to as Lake Tahoe, or simply Tahoe; its English name is derived from its Washo name, Dáʔaw. More than 75% of the lake's watershed is national forest land, covered by the Lake Tahoe Basin Management Unit of the United States Forest Service.

Broken Top is a glacially eroded complex stratovolcano. It lies in the Cascade Volcanic Arc, part of the extensive Cascade Range in the U.S. state of Oregon. Located southeast of the Three Sisters peaks, the volcano, residing within the Three Sisters Wilderness, is 20 miles (32 km) west of Bend, Oregon, in Deschutes County. Eruptive activity stopped roughly 100,000 years ago, and erosion by glaciers has since reduced the volcano's cone to where its contents are exposed. There are two named glaciers on the peak, Bend and Crook Glacier.

Diverse species of flora and fauna inhabit the area, which is subject to frequent snowfall, occasional rain, and extreme temperature variation between seasons. Broken Top and its surrounding area constitute popular destinations for hiking, climbing, and scrambling.
