The nickname of the 49th state, Alaska, is the "Last Frontier." Purchased from Russia for $7 million in 1867, Alaska is the largest state in area and is the largest peninsula in the Western Hemisphere. Mt. McKinley in the Alaska Range is North America's highest peak at 20,320 feet and one of the greatest challenges for mountain climbers. Juneau is the state's capital, and Alaska state flower is the pale-blue forget-me-not. Alaska became the 49th state on January 3, 1959; it was the first new state in the Union since 1912.
