In short: Often called the Alaska Panhandle, this region is a labyrinth of islands and waterways larger than Indiana. Because of its extreme, mountainous terrain, most communities remain disconnected from the road network, relying entirely on ferries, floatplanes, and ships to navigate a landscape defined by glaciers, salmon, and ancient forests.

Southeast Alaska covers 35,138 square miles, forming a complex archipelago that serves as the northern terminus of the Inside Passage. This protected waterway has functioned as a vital corridor for centuries, first for Tlingit, Haida, and Tsimshian peoples, and later for gold-rush steamships. Today, the region is dominated by the Tongass National Forest, the largest national forest in the United States, which was established in 1902 as the Alexander Archipelago Forest Reserve. The climate here is uniquely mild for Alaska, characterized by temperate rainforests and winter temperatures that often stay above freezing.

The region's geography dictates its economy and infrastructure. With almost no road connections between towns—save for Hyder, Skagway, and Haines—the Alaska Marine Highway and regional air carriers are essential. Juneau, the state capital, serves as the primary aerial hub, while Ketchikan functions as a secondary center for the south. The economy has shifted significantly over time; while logging was once a primary industry, it has declined alongside the closure of major pulp mills. Commercial fishing, mining, and a massive cruise ship industry now anchor the regional economy.

Tourism exploded in the late 20th century, spurred by the success of the television series The Love Boat, which featured Alaska episodes and helped popularize cruise travel between 1977 and 1987. By 2019, approximately 1.3 million people visited Alaska via cruise ship. Meanwhile, mining remains a critical, if complex, economic driver. Active sites like the Greens Creek mine, which focuses on silver, operate alongside ongoing debates regarding transboundary mining issues, where projects in British Columbia upstream of rivers like the Unuk and Stikine have raised environmental concerns for the region's vital watersheds.
