Introduction to South-Central District: The Alaskan Mountains clearly outline the curve of the Gulf of Alaska, and also form the appearance of South-Central Alaska. More than half of Alaska's residents live here, and its glaciers, fjords, roadside lakes, calm beaches and salmon-rich rivers are beautiful all year round. There are large tracts of farmland, fishing areas, national parks, ski resorts and the cosmopolitan city of Anchorage. All important highway transportation lines in the state pass through this area, as do the Alaska Railroad and the Alaska Navigation System. Anchorage is an important transportation hub and can easily reach Mount McKinley, Denali National Park, Fairbanks, etc. Anchorage is also a must-stop on the Pacific Great Circle Route.
