full_context: Document 1: Capital punishment in the United States: All of the executions which have taken place since the 1936 hanging of Bethea in Owensboro have been conducted within a wall or enclosure. For example, Fred Adams was legally hanged in Kennett, Missouri, on April 2, 1937, within a 10-foot (3 m) wooden stockade. Roscoe "Red" Jackson was hanged within a stockade in Galena, Missouri, on May 26, 1937. Two Kentucky hangings were conducted after Galena in which numerous persons were present within a wooden stockade, that of John "Peter" Montjoy in Covington, Kentucky on December 17, 1937, and that of Harold Van Venison in Covington on June 3, 1938. An estimated 400 witnesses were present for the hanging of Lee Simpson in Ryegate, Montana, on December 30, 1939. The execution of Timothy McVeigh on June 11, 2001 was witnessed by some 300 people, some by closed-circuit television.
Document 2: Capital punishment in the United States: Various methods have been used in the history of the American colonies and the United States but only five methods are currently used. Historically, burning, crushing, breaking on wheel, and bludgeoning were used for a small number of executions, while hanging was the most common method. The last person burned at the stake was a black slave in South Carolina in August 1825. The last person to be hanged in chains was a murderer named John Marshall in West Virginia on April 4, 1913. Although beheading was a legal method in Utah from 1851 to 1888, it was never used.
Document 3: Snake Creek, Oklahoma: Snake Creek is a census-designated place (CDP) in Mayes County, Oklahoma, United States. The population was 298 at the 2000 census.
Document 4: Spokane River: The Spokane River is a tributary of the Columbia River, approximately long, in northern Idaho and eastern Washington in the United States. It drains a low mountainous area east of the Columbia, passing through the Spokane Valley and the city of Spokane, Washington.
Document 5: Capital punishment in the United States: The largest single execution in United States history was the hanging of 38 American Indians convicted of murder and rape during the Dakota War of 1862. They were executed simultaneously on December 26, 1862, in Mankato, Minnesota. A single blow from an axe cut the rope that held the large four-sided platform, and the prisoners (except for one whose rope had broken and who had to be re-hanged) fell to their deaths. The second-largest mass execution was also a hanging: the execution of 13 African-American soldiers for taking part in the Houston Riot of 1917. The largest non-military mass execution occurred in one of the original thirteen colonies in 1723, when 26 convicted pirates were hanged in Newport, Rhode Island by order of the Admiralty Court.
Document 6: Ripple River: The Ripple River is a small river that starts at the outlet of Bay Lake of Crow Wing County, Minnesota, and ends in Aitkin, the county seat of Aitkin County, at its confluence with the Mississippi River. The river follows a circuitous route: as the crow flies, the distance between its source and mouth is , but the total stream length is .
Document 7: Mississippi River: The Mississippi River is the chief river of the second - largest drainage system on the North American continent, second only to the Hudson Bay drainage system. The stream is entirely within the United States (although its drainage basin reaches into Canada), its source is Lake Itasca in northern Minnesota and it flows generally south for 2,320 miles (3,730 km) to the Mississippi River Delta in the Gulf of Mexico. With its many tributaries, the Mississippi's watershed drains all or parts of 31 U.S. states and two Canadian provinces between the Rocky and Appalachian Mountains. The Mississippi ranks as the fourth - longest and fifteenth - largest river in the world by discharge. The river either borders or passes through the states of Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana.
Document 8: Cann River: The Cann River rises southwest of Granite Mountain in remote country on the eastern boundary of the Errinundra National Park and flows generally east, then south, then east, then south through the western edge of the Coopracambra National Park and through the Croajingolong National Park, joined by seventeen minor tributaries before reaching its mouth with Bass Strait, at the Tamboon Inlet in the Shire of East Gippsland.

Document 9: Minnesota River: The Minnesota River is a tributary of the Mississippi River, approximately 332 miles (534 km) long, in the U.S. state of Minnesota. It drains a watershed of nearly , in Minnesota and about in South Dakota and Iowa.
Document 10: Capital punishment in the United States: Possibly in part due to expedited federal habeas corpus procedures embodied in the Antiterrorism and Effective Death Penalty Act of 1996, the pace of executions picked up, reaching a peak of 98 in 1999 and then they declined gradually to 28 in 2015. Since the death penalty was reauthorized in 1976, 1,411 people have been executed, almost exclusively by the states, with most occurring after 1990. Texas has accounted for over one-third of modern executions (although only two death sentences were imposed in Texas during 2015, with the courts preferring to issue sentences of life without parole instead) and over four times as many as Oklahoma, the state with the second-highest number. California has the greatest number of prisoners on death row, has issued the highest number of death sentences but has held relatively few executions.
Document 11: Salem witch trials: The Salem witch trials were a series of hearings and prosecutions of people accused of witchcraft in colonial Massachusetts between February 1692 and May 1693. More than 200 people were accused, nineteen of which were found guilty and executed by hanging (fourteen women and five men). One other man was pressed to death for refusing to plead, and at least five people died in jail. It was the deadliest witch hunt in the history of the United States.
Document 12: Snake River (St. Croix River tributary): The Snake River with its tributaries drains a 1,009 square miles (2,610 km) area of Aitkin, Kanabec, Mille Lacs and Pine counties. After initially flowing southward from its headwaters in southern Aitkin County, the Snake flows through Kanabec County, turning eastward near Mora, Minnesota, following a minor fault line. It drains into the St. Croix River 13 miles (21 km) east of Pine City, Minnesota.
Document 13: Capital punishment in Canada: Capital punishment in Canada dates back to Canada's earliest history, including its period as a French colony and, after 1763, its time as a British colony. From 1867 to the elimination of the death penalty for murder on July 14, 1976, 1,481 people had been sentenced to death, and 710 had been executed. Of those executed, 697 were men and 13 were women. The only method used in Canada for capital punishment of civilians after the end of the French regime was hanging. The last execution in Canada was the double hanging of Arthur Lucas and Ronald Turpin on December 11, 1962, at Toronto's Don Jail.
Document 14: South Fork Humboldt River: The South Fork of the Humboldt River has its origins in a fan-shaped group of canyons draining the western slopes of the Ruby Mountains in northeastern Nevada. These headwaters run from Ruby Dome south to King Peak, and include Echo, Box, Kleckner, North Furlong, Long, Segunda, Drown, and Rattlesnake Canyons. Streams draining these canyons exit the mountains and converge at an elevation of , near the town of Lee and within the tribal lands of the Te-Moak tribe of the South Fork Band of the Western Shoshone.
Document 15: Capital punishment in the United States: Since 1642 (in the 13 colonies, the United States under the Articles of Confederation, and the current United States) an estimated 364 juvenile offenders have been put to death by the states and the federal government. The earliest known execution of a prisoner for crimes committed as a juvenile was Thomas Graunger in 1642. Twenty-two of the executions occurred after 1976, in seven states. Due to the slow process of appeals, it was highly unusual for a condemned person to be under 18 at the time of execution. The youngest person to be executed in the 20th century was George Stinney, who was electrocuted in South Carolina at the age of 14 on June 16, 1944. The last execution of a juvenile may have been Leonard Shockley, who died in the Maryland gas chamber on April 10, 1959, at the age of 17. No one has been under age 19 at time of execution since at least 1964. Since the reinstatement of the death penalty in 1976, 22 people have been executed for crimes committed under the age of 18. Twenty-one were 17 at the time of the crime. The last person to be executed for a crime committed as a juvenile was Scott Hain on April 3, 2003 in Oklahoma.
