Paleo-Indian in the context of "North Cascades National Park"

Colorado is a landlocked state in the Western United States. It is one of the Mountain states, and Southwestern region of the United States, sharing the Four Corners region with Arizona, New Mexico, and Utah. It is also bordered by Wyoming to the north, Nebraska to the northeast, Kansas to the east, and Oklahoma to the southeast. Colorado is noted for its landscape of mountains, forests, high plains, mesas, canyons, plateaus, rivers, and desert lands. It encompasses most of the Southern Rocky Mountains, as well as the northeastern portion of the Colorado Plateau and the western edge of the Great Plains. Colorado is the eighth-largest U.S. state by area and the 21st by population. The United States Census Bureau estimated the population of Colorado to be 5,957,493 as of July 1, 2024, a 3.2% increase from the 2020 United States census.

The region has been inhabited by Native Americans and their Paleo-Indian ancestors for at least 13,500 years and possibly much longer. The eastern edge of the Rocky Mountains was a major migration route for early peoples who spread throughout the Americas. In 1848, much of the Nuevo México region was annexed to the United States with the Treaty of Guadalupe Hidalgo. The Pike's Peak Gold Rush of 1858–1862 created an influx of settlers. On February 28, 1861, U.S. President James Buchanan signed an act creating the Territory of Colorado, and on August 1, 1876, President Ulysses S. Grant signed Proclamation 230, admitting Colorado to the Union as the 38th state. The Spanish adjective "colorado" means "colored red" or "ruddy". Colorado is nicknamed the "Centennial State" because it became a state 100 years (and four weeks) after the signing of the United States Declaration of Independence.

The region that is today the U.S. state of Colorado has been inhabited by Native Americans and their Paleo-Indian ancestors for at least 13,500 years and possibly more than 37,000 years. The eastern edge of the Rocky Mountains was a major migration route that was important to the spread of early peoples throughout the Americas. The Lindenmeier site in Larimer County contains artifacts dating from approximately 8720 BCE.

When explorers, early trappers, hunters, and gold miners visited and settled in Colorado, the state was populated by American Indian nations. Westward expansion brought European settlers to the area and Colorado's recorded history began with treaties and wars with Mexico and American Indian nations to gain territorial lands to support the transcontinental migration. In the early days of the Colorado gold rush, Colorado was a Territory of Kansas and Territory of Jefferson. On August 1, 1876, Colorado was admitted as a state, maintaining its territorial borders.

Manitoulin Island (/ˌmænəˈtuːlɪn/ MAN-ə-TOO-lin) is an island in Lake Huron, located within the borders of the Canadian province of Ontario, in the bioregion known as Laurentia. With an area of 2,766 km (1,068 sq mi), it is the largest lake island in the world, large enough that it has over 100 lakes itself. In addition to the historic Anishinaabe and European settlement of the island, archaeological discoveries at Sheguiandah have demonstrated Paleo-Indian and Archaic cultures dating from 10,000 BC to 2,000 BC.

The current name of the island is the English version, via French, of the Ottawa or Ojibwe name Manidoowaaling (ᒪᓂᑝᐙᓕᓐᒃ), which means "cave of the spirit". It was named for an underwater cave where a powerful spirit is said to live. By the 19th century, the Odawa "l" was pronounced as "n". The same word with a newer pronunciation is used for the town Manitowaning (19th-century Odawa "Manidoowaaning"), which is located on Manitoulin Island near the underwater cave where legend has it that the spirit dwells. The modern Odawa name for Manitoulin Island is Mnidoo Mnising, meaning "Spirit Island".

The Oklahoma panhandle (formerly called No Man's Land, the Public Land Strip, the Neutral Strip, or Cimarron Territory) is a salient in the extreme northwestern region of the U.S. state of Oklahoma. Its constituent counties are, from west to east, Cimarron, Texas and Beaver. As with other salients in the United States, its name comes from the similarity of its shape to the handle of a pan. Its largest city is Guymon in Texas County. Black Mesa State Park, located in Cimarron County, is the highest point in the state. Other points of interest include Beaver Dunes Park, Optima Lake, and the Optima National Wildlife Refuge. Oklahoma Panhandle State University is ten miles away from Guymon.

Paleo-Indian people settled in the region around 8450 BCE. Native American horticulturists inhabited the region before the European colonists arrived in the 16th century. The area became part of New Spain with the Adams–Onís Treaty of 1819, which set the western boundary of the Louisiana Purchase at the 100th meridian. The outcome of the Mexican War of Independence made the panhandle a part of Mexico in 1821. The area was part of the Texas Republic from its formation in 1836 until Texas became part of the United States in 1846, which left the area federal property. The area was incorporated into Oklahoma Territory and later split into three counties when Oklahoma obtained statehood in 1907.

In prehistoric archaeology, scrapers are unifacial tools thought to have been used for hideworking and woodworking. Many lithic analysts maintain that the only true scrapers are defined on the base of use-wear, and usually are those that were worked on the distal ends of blades—i.e., "end scrapers" (French: grattoir). Other scrapers include the so-called "side scrapers" or racloirs, which are made on the longest side of a flake, and notched scrapers, which have a cleft on either side that may have been used to attach them to something else.

Scrapers are typically formed by chipping the end of a flake of stone in order to create one sharp side and to keep the rest of the sides dull to facilitate grasping it. Most scrapers are either circle or blade-like in shape. The working edges of scrapers tend to be convex, and many have trimmed and dulled lateral edges to facilitate hafting. One important variety of scraper is the thumbnail scraper, a scraper shaped much like its namesake. This scraper type is common at Paleo-Indian sites in North America. Scrapers are one of the most varied lithic tools found at archaeological sites. Due to the vast array of scrapers there are many typologies that scrapers can fall under, including tool size, tool shape, tool base, the number of working edges, edge angle, edge shape, and many more.
