In 2005, Gordon Hempton made a single spot within the Hoh Rain Forest famous for its serenity. But now it’s noisier than ever. For outdoor enthusiasts, Olympic National Park offers a smorgasbord of ecosystems: rocky peaks, driftwood-strewn beaches and high-mountain meadows filled with wildflowers and bears. But its rain-fed temperate rain forests host some of the biggest trees in the world.  The Hoh Rain Forest captured audio ecologist Hempton’s imagination for its serene quiet, free from the intrusion of human noise. For decades, he has recorded the birdsong, bugling elk and pitter-patter of rain in painstaking detail. He’s even declared one small section  “One Square Inch of Silence” as a monument to preserve the natural soundscape of Olympic National Park. But in the decades since, air traffic over the Olympic Peninsula has made that square inch louder, not quieter — with the Navy’s “Growler” fighter jets providing the biggest obstacle. In this episode of Crosscut Escapes, Hempton and fellow bioacoustic ecologist Lauren Kuehne join us on a trip deep into the forest in search of silence. --- Credits Host: Ted Alvarez Engineering: Karalyn Smith, Piranha Partners Music: The Explorist
