Alaska, the largest state in the United States by area, is known as "The Last Frontier" due to its vast, untamed wilderness and relatively recent settlement history. Purchased from Russia in 1867, Alaska became a state in 1959. The nickname reflects the state's rugged landscapes, including towering mountains, expansive forests, and extensive coastline, as well as its rich natural resources. Alaska's wild beauty attracts adventurers and nature enthusiasts seeking to experience its unique environment and wildlife.
