Indiana Dunes National Park
Tonight at Indiana Dunes National Park
Lake Michigan's might has influenced Indiana Dunes for millennia. Wind and waves have shaped the land, leaving a rich mosaic of habitats along these 15 miles of Indiana coast. Over 50 miles of trails lead through shifting sand dunes, quiet woodlands, sunny prairies and lush wetlands. Known for its striking plant and bird diversity, it's easy to find inspiration throughout the park’s 16,000 acres.

What this latitude gives you
From 41.6° north, anything above declination +48.4° is circumpolar here: it never sets, so it is available on every clear night of the year. Anything below declination -48.4° never clears the horizon at all.
Astronomical darkness lasts through every night of the year here, including midsummer, which makes this a rare site for a June or July imaging trip.
