Rocky Mountains The Rocky Mountains, also known as the Rockies, are a major mountain range in western North America. The Rocky Mountains stretch more than 3,000 miles (4,800Â km) from the northernmost part of British Columbia, in western Canada, to New Mexico, in the Southwestern United States. Within the North American Cordillera, the Rockies are somewhat distinct from the Pacific Coast Ranges, Cascade Range, and the Sierra Nevada, which all lie further to the west.
Sierra Nevada (U.S.) In the Cretaceous, a subduction zone formed at the edge of the continent.[20] This means that an oceanic plate started to dive beneath the North American plate. Magma formed through the subduction of the ancient Farallon Plate rose in plumes (plutons) deep underground, their combined mass forming what is called the Sierra Nevada batholith. These plutons formed at various times, from 115 Ma to 87 Ma.[21] The earlier plutons formed in the western half of the Sierra, while the later plutons formed in the eastern half of the Sierra.[18] By 66 Ma, the proto-Sierra Nevada had been worn down to a range of rolling low mountains, a few thousand feet high.

Sierra Madre Occidental Railroads came to the area starting in the 1880s and 1890s, which allowed many old mines in the region to reopen at a profit.[119] Since most of the railroads were American, the foreign influence led to unrest among the people living in the mountains, causing the Tomochic rebellion in 1892.[120] In addition to the railroads, canals were constructed in the 1890s in the Yaqui and Mayo river valleys.[121] However, these canal projects failed due to the resistance that the natives of the valleys put up against the projects.[122] Loggers began arriving in the mountains in the late 1800s. In response to the new industry, the Tarahumara moved further into the canyons.[119]
