Continental Divide of the AmericasThe Continental Divide of the Americas (also known as the Great Divide, the Western Divide or simply the Continental Divide; Divisoria continental de América, Gran Divisoria) is the principal, and largely mountainous, hydrological divide of the Americas. The Continental Divide extends from the Bering Strait to the Strait of Magellan, and separates the watersheds that drain into the Pacific Ocean from those river systems that drain into the Atlantic and Arctic Ocean, including those that drain into the Gulf of Mexico, the Caribbean Sea, and Hudson Bay.
Westward Expansion TrailsIn the history of the American frontier, pioneers built overland trails throughout the 19th century, especially between 1829 and 1870, as an alternative to sea and railroad transport. These immigrants began to settle much of North America west of the Great Plains as part of the mass overland migrations of the mid-19th century. Settlers emigrating from the eastern United States did so with various motives, among them religious persecution and economic incentives, to move from their homes to destinations further west via routes such as the Oregon, California, and Mormon Trails.
Intermountain WestThe Intermountain West, or Intermountain Region, is a geographic and geological region of the Western United States. It is located between the front ranges of the Rocky Mountains on the east and the Cascade Range and Sierra Nevada on the west. The Intermountain West has a basin and range and plateau topography. Some of the region's rivers reach the Pacific Ocean, such as the Columbia River and Colorado River. Other regional rivers and streams are in endorheic basins and cannot reach the sea, such as the Walker River and Owens River.
PalouseThe Palouse (pəˈluːs ) is a distinct geographic region of the northwestern United States, encompassing parts of north central Idaho, southeastern Washington, and, by some definitions, parts of northeast Oregon. It is a major agricultural area, primarily producing wheat and legumes. Situated about north of the Oregon Trail, the region experienced rapid growth in the late 19th century. The Palouse is home to two land-grant universities: the University of Idaho in Moscow and Washington State University in Pullman.
Manifest destinyManifest destiny was a cultural belief in the 19th-century United States that American settlers were destined to expand across North America. There were three basic tenets to the concept: The special virtues of the American people and their institutions The mission of the United States to redeem and remake the West in the image of the agrarian East An irresistible destiny to accomplish this essential duty Historians have emphasized that "manifest destiny" was always contested.
Provisional Government of OregonThe Provisional Government of Oregon was a popularly elected settler government created in the Oregon Country, in the Pacific Northwest region of North America. Its formation had been advanced at the Champoeg Meetings since February 17, 1841, and it existed from May 2, 1843 until March 3, 1849, and provided a legal system and a common defense amongst the mostly American pioneers settling an area then inhabited by the many Indigenous Nations.
