A change of climate around 7000 years ago dried up much of the Great Basin , forcing the Shoshone people northward into the mountainous areas of central Idaho. Most of what

5824-439: The first people might not have come to North America by land, as previously theorized. On the contrary, they probably came through the water, using a Pacific coastal route. The most parsimonious explanation we think is that people came down the Pacific Coast, and as they encountered the mouth of the Columbia River, they essentially found an off-ramp from this coastal migration and also found their first viable interior route to

5928-448: The first to discover gold in the forest at the eponymous Grimes Creek on August 2, 1862. Subsequent gold discoveries at Rocky Bar in 1863 and Atlanta in 1864 increased the rush of people to Idaho, and in 1863 Idaho City, with a population of 6,267, surpassed Portland, Oregon as the largest city in the Pacific Northwest . The Idaho gold rush was largely over by 1870, and the population of the Boise Basin fell from 16,000 to 3,500. In 1898
