The shore of a nameless pond just south of Alaska's Gates of the Arctic National Park and Preserve. Locals call it Float Pond; it's on the rim of the aural zone–the halo over the northern hemisphere where the aurora borealis are brightest and most psychedelic. Best in the Lower 48? Maine's Deboullie Mountain, near the Canadian border.
To get to Float, snowshoe 2.5 miles south from Bettles (population 25) on the only road in town. Sit on the south bank to put the village's (one or two) lights behind you and the best show in front. Catch a flight to Bettles from Fairbanks. Read current light reports at spaceweather.com.
