I am glad to be working with Yellowstone National Park to edit a series of recordings from their ongoing soundscape research. I just received a hard drive with hundreds of hours of remote recordings from locations around the park. I even had a chance to make a few recordings of my own last week near Pebble Creek Pond in the Lamar Valley. I'll post a few to my Soundcloud page soon. Meanwhile, check out our Yellowstone collection at the Acoustic Atlas.
