Fairbanks began by accident. In August 1901 the steamboat Lavelle Young ran aground in the Chena River, and the trader E. T. Barnette, who was on his way to somewhere else, was put ashore with his supplies. Gold prospectors working in the hills saw the smoke, talked him into staying, and the trading post became a gold town and then the hub of Interior Alaska. Today about 32,500 people live in the city, and in winter what you notice is how normal everything is: schools, supermarkets and a university carry on at temperatures that would close a city anywhere else. The University of Alaska Fairbanks is also why the aurora is taken seriously here.
Why three days, and why not fewer? Fairbanks sits under the auroral oval, and local tourism people say the lights show up on average four nights out of five when the sky is clear and dark enough. The catch is the clear part: cloud beats any forecast. Their advice is at least three nights, which gives a better than 90 percent chance, and more nights only help. The sights fit in two days, and the other goes to Chena Hot Springs. If you can add a fourth or fifth night, do it for the sky, not for more museums.
Day one is the university, downtown and Alaskaland (Pioneer Park), with an easy first aurora watch. Day two is Chena Hot Springs, 56 miles (91 km) out. Day three goes to North Pole, the pipeline and Fox, then up Cleary Summit. Start on a Wednesday: it keeps Lemongrass (closed Sundays) and the Fox brewery (closed Mondays and Tuesdays) open on the days you need them.
