Asa Gray
Asa Gray (November 18, 1810 – January 30, 1888) is considered the most important American botanist of the 19th century. His ''Darwiniana'' was considered an important explanation of how religion and science were not necessarily mutually exclusive. Gray was adamant that a genetic connection must exist between all members of a species. He was also strongly opposed to the ideas of hybridization within one generation and special creation in the sense of its not allowing for evolution. He was a strong supporter of Darwin, although Gray's theistic evolution was guided by a Creator. As a professor of botany at Harvard University for several decades, Gray regularly visited, and corresponded with, many of the leading natural scientists of the era, including Charles Darwin, who held great regard for him. Gray made several trips to Europe to collaborate with leading European scientists of the era, as well as trips to the southern and western United States. He also built an extensive ne ...

Intermontane
Intermontane is a physiographic adjective formed from the prefix " inter-" (''signifying among, between, amid, during, within, mutual, reciprocal'') and the adjective "montane" (inhabiting, or growing in mountainous regions, especially cool, moist upland slopes below the timberline). The corresponding ''physiographic'' noun is intermountain, while the noun ''intermontane'' is an ''ecologic'' noun meaning ''among, between, amid, or within " flora and fauna of a montane habitat.''" As an example, an alpine region would be an intermontane for a species that migrates between a glacial region and a subalpine region. Use of the term *Intermontane Basin, a wide valley between mountain ranges that is partly filled with alluvium such as New Zealand's Mackenzie Basin. *Intermontane Belt, a physiogeological region in the North American Pacific Northwest. *Intermontane Plateaus, the United States physiographic region of the Intermountain West. *Intermontane Steppe, a term used mainly i ...

Rocky Mountains
The Rocky Mountains, also known as the Rockies, are a major mountain range and the largest mountain system in North America. The Rocky Mountains stretch in straight-line distance from the northernmost part of western Canada, to New Mexico in the southwestern United States.

Its southernmost point is near the Albuquerque area adjacent to the Rio Grande rift and north of the Sandia–Manzano Mountain Range. Being the easternmost portion of the North American Cordillera, the Rockies are distinct from the tectonically younger Cascade Range and Sierra Nevada, which both lie farther to its west. The ...
