Close your eyes and imagine a wilderness four times bigger than Yellowstone National Park. Imagine a landscape north of the Arctic Circle with rugged mountains, vast expanses of treeless tundra, glaciated valleys, forests and many rivers and lakes. In the winter the weather can dip below -50 degrees Fahrenheit and in the month of June the sun is out for 24 hours. This vast and expansive landscape is the home of Gates Of The Arctic National Park & Preserve, where this episode hears from its superintendent, Mark Dowdle.
