The Southeast Panhandle stretches some 500 mi from Yakutat at its northernmost point to Ketchikan and Metlakatla at its southern end. At its widest point, the region measures only 140 mi, and in the upper Panhandle just south of Yakutat, at 30 mi across, it's downright skinny by Alaska standards. Most of the Panhandle consists of a sliver of mainland buffered on the west by islands and on the east by the imposing peaks of the Coast Mountains.
Those numerous coastal islands—more than 1,000 throughout the Inside Passage—collectively constitute the Alexander Archipelago. Most of them sport mountainous terrain with lush covers of timber, though large clear-cuts are also common. Most communities are on islands rather than on the mainland. The principal exceptions are Juneau, Haines, and Skagway, plus the hamlets of Gustavus and Hyder. Island outposts include Ketchikan, Wrangell, Petersburg, Sitka, and the villages of Craig, Pelican, Metlakatla, Kake, Angoon, and Hoonah. Bordering Alaska just east of the Panhandle lies the Canadian province of British Columbia.
