Idaho ( /ˈaɪdəhoʊ/ (help·info)) is a state in the Pacific Northwest region of the United States of America. The state's largest city and capital is Boise. Residents are called "Idahoans." Idaho was admitted to the Union on 3 July 1890 as the 43rd state.
Idaho is a mostly mountainous state larger than the whole of New England. It is landlocked, surrounded by the states of Washington, Oregon, Nevada, Utah, Wyoming, Montana and the Canadian Province of British Columbia. However, the network of dams and locks on the Columbia River and Snake River make Lewiston, Idaho the farthest inland seaport on the west coast of the continental United States.
To residents of the state and regular visitors, Idaho is regarded as a highly outdoors-oriented community. Central Idaho is home to one of North America's oldest ski resorts, Sun Valley, where the world's first chairlift was installed. Snow sports are important keystones of Idaho's identity, with a ski resort adjacent to nearly every urban area. Whitewater rafting and kayaking are among the state's major pastimes. Hell's Canyon and the Salmon River boast some of North America's finest whitewater, with the nearby town of Riggins, ID serving as the state's informal whitewater capital.
According to the United States Census Bureau, in 2008 the population for Idaho was estimated to be 1,523,816. The state's postal abbreviation is ID. Idaho's nickname is the Gem State because nearly every known gem has been found there. In addition, Idaho is one of only two places in the world where star garnets can be found (the other is the Himalaya Mountains, in India), and is the only place six pointed star garnets have been found. The state motto is Esto Perpetua (Latin for "Let it be forever").
