6. Northern United States: Chasing the Aurora in the Lower 48
Advertisement
Although the Northern Lights are usually connected with high-latitude locations like Alaska or Scandinavia, the northern areas of the contiguous United States present unexpected chances for aurora viewing, however under more difficult and less predictable conditions. Particularly during seasons of increased solar activity, states like Michigan's Upper Peninsula, northern Minnesota, Wisconsin, the Dakotas, and Montana lay in latitudes where the aurora borealis can periodically be seen. Although they are not as regularly trustworthy for Northern Lights sightings as their Arctic equivalents, these places give lower 48 state residents easily available choices to witness this celestial event without resorting to foreign travel. These areas usually have few aurora viewing seasons; the best chances usually arise during the equinox months of March or April and September or October, when the Earth's axial tilt lines up with the solar wind generating auroral activity.
Often known to just as the "U.P.," the Upper Peninsula of Michigan is among the most likely places in the contiguous United States to see auroras. Its northerly latitude, together with large wilderness regions and dark sky preserves, produces conditions that might compete with some international aurora locations during periods of high geomagnetic activity. With its secluded beaches and high hills giving unhindered views of the northern horizon, the Keweenaw Peninsula, extending into Lake Superior, offers especially good viewing opportunities. Dark sky and occasional amazing aurora displays are well-known features of the Boundary Waters Canoe Area Wilderness and North Shore of Lake Superior in Minnesota. These places gain from their close proximity to the Canadian border as well as from the large, unspoilt boreal forest stretches that reduce light pollution. With state parks and woods providing easily accessible viewing sites away from metropolitan light sources, Wisconsin's northern counties—especially those surrounding Lake Superior—also show possibility for aurora sightings.
Though less often connected with Northern Lights viewing, the Dakotas and Montana might present unexpected possibilities during times of strong auroral activity. The large, broad plains and badlands of North and South Dakota offer clear views of the night sky, which let one find even small auroral glows on the northern horizon. Along with some of the most striking scenery in the lower 48 states, Glacier National Park and the neighbouring wilderness areas provide Montana with the chance of aurora sightings. The difficulty of aurora viewing in these areas is the erratic nature of the phenomena and the necessity of exact timing and ideal conditions of temperature. Unlike in more northerly latitudes, where the aurora may be seen for prolonged durations or even several nights in succession, sightings in the northern United States are frequently brief, lasting only a few hours or perhaps several nights in sequence.
Aurora chasers in the northern United States mostly depend on forecasting tools and real-time solar activity monitoring if they are to maximise their chances of success. Daily aurora predictions from the National Oceanic and Atmospheric Administration (NOAA) are quite helpful for organising viewing efforts. Long-term travel planning is difficult though, since these projections usually only look forward by a few days to a week. This unpredictability calls for a flexible strategy since many aficionados keep a condition of ready to rapidly organise when the conditions seem favourable. For the aurora-watching population in these areas, social media and aurora alert networks have become vital instruments since they enable quick spread of information on continuous displays and viewing conditions. Notwithstanding the difficulties, the reward of seeing the Northern Lights from the contiguous United States can be very unique and memorable, tying viewers to the larger rhythms of the solar system and the Earth's place within it.
