Juneau is Alaska's capital, however you can't get there by road. Southeast Alaska is sandwiched between the rugged coastal mountain range and the Pacific Ocean. Constructing roads between many of the towns and cities of SE Alaska is prohibitively expensive and sometimes impossible.
Access to Juneau is only by air and sea.
So if you miss the boat you have to fly out.
Downtown Juneau sits at sea level, with tides averaging 16 feet (5 m), below steep mountains about 3,500 feet (1,100 m) to 4,000 feet (1,200 m) high. Atop these mountains is the Juneau Icefield, a large ice mass from which about 30 glaciers flow; two of these, the Mendenhall Glacier and the Lemon Creek Glacier, are visible from the local road system; the Mendenhall glacier has been generally retreating; its front face is declining both in width and height
