Black Hills land claim

The Black Hills land claim is an ongoing land dispute between Native Americans from the Sioux Nation and the United States government. The land in question was pledged to the Sioux Nation in the Fort Laramie Treaty of April 29, 1868, but effectively nullified without the Nation's consent in the Indian Appropriations Bill of 1876. That bill “denied the Sioux all further appropriation and treaty-guaranteed annuities” until they gave up the Black Hills. A Supreme Court case was ruled in favor of the Sioux in 1980. The Sioux have outstanding issues with the ruling and have not collected the funds. As of 2011, the award was worth over $1 billion.

Great Sioux War of 1876

The Great Sioux War of 1876, also known as the Black Hills War, was a series of battles and negotiations which occurred in 1876 and 1877 between the Lakota Sioux, Northern Cheyenne, and the United States. The cause of the war was the desire of the U.S. government to obtain ownership of the Black Hills. Gold had been discovered in the Black Hills, settlers began to encroach onto Native American lands, and the Sioux and Cheyenne refused to cede ownership to the U.S. Traditionally, the United States military and historians place the Lakota at the center of the story, especially given their numbers, but some Native Americans believe the Cheyenne were the primary target of the U.S. campaign.

Nez Perce in Yellowstone ParkW
Nez Perce in Yellowstone Park

The Nez Perce in Yellowstone Park was the flight of the Nez Perce Indians through Yellowstone National Park between August 20 and Sept 7, during the Nez Perce War in 1877. As the U.S. army pursued the Nez Perce through the park, a number of hostile and sometimes deadly encounters between park visitors and the Indians occurred. Eventually, the army's pursuit forced the Nez Perce off the Yellowstone plateau and into forces arrayed to capture or destroy them when they emerged from the mountains of Yellowstone onto the valley of Clark's Fork of the Yellowstone River.

The Nez Perce War was an armed conflict that pitted several bands of the Nez Perce tribe of Native Americans and their allies, a small band of the Palouse tribe led by Red Echo (Hahtalekin) and Bald Head, against the United States Army. The conflict, fought between June and October 1877, stemmed from the refusal of several bands of the Nez Perce, dubbed "non-treaty Indians," to give up their ancestral lands in the Pacific Northwest and move to an Indian reservation in Idaho. This forced removal was in violation of the 1855 Treaty of Walla Walla, which granted the tribe 7.5 million acres in their ancestral lands and the right to hunt and fish in lands ceded to the government.

Red Cloud's WarW
Red Cloud's War

Red Cloud's War was an armed conflict between the Lakota, Northern Cheyenne, and Northern Arapaho on one side and the United States in Wyoming and Montana territories from 1866 to 1868. The war was fought over control of the western Powder River Country in present north-central Wyoming. This grassland, rich in buffalo, was traditionally Crow Indian land, but the Lakota had recently taken control. The Crow tribe held the treaty right to the disputed area, according to the major agreement reached at Fort Laramie in 1851. All involved in "Red Cloud's War" were parties in that treaty.

Vore Buffalo JumpW
Vore Buffalo Jump

The Vore Buffalo Jump is an archeological site in Crook County, Wyoming. A sinkhole, formed where gypsum soil was eroded, leaving a steep-sided pit about 40 feet (12 m) deep and 200 feet (61 m) in diameter. Native American hunters could stampede bison in the direction of the pit, which was deep enough to kill or disable the animals that were driven into it. The location is one of a number of buffalo jump sites in the north central United States and southern Canada. The Vore site was used as a kill site and butchering site from about 1500 AD to about 1800 AD. Archeological investigations in the 1970s uncovered bones and projectile points to a depth of 15 feet (4.6 m). About ten tons of bones were removed from the site. About five percent of the site has been excavated, and the pit is estimated to contain the remains of 20,000 buffalo.
