 Welcome to our Yellowstone as presented by Montana State University Libraries Acoustic Atlas. The Acoustic Atlas is MSU Libraries digital audio archive of animal and environmental sounds from Montana, the Greater Yellowstone Ecosystem, and the American West. These recordings and many others can be accessed at acousticatalyst.org. The first reporting we're going to hear is the sound of a pika, a small animal that lives in Yellowstone's high alpine region. The next recording we'll hear are the sounds of spadefoot, toads, and boreal chorus frogs. The next recording is the sound of Vixen Geyser erupting in Norse Geyser Basin. The next recording is the sound of San Hill Cranes as they fly south on their migration. The following recording you may recognize as Yellowstone's famous gray walls. The next recording contains the sounds of elk, canada geese, looms, coots, and red squirrels. Listen now to the sounds of the iconic American Bison. Familiar sound in September is the bugling of bull elk in Yellowstone. The last sound in our presentation is that of the meeting of two grizzly bears. Remember, every natural environment, every ecosystem has its voice. acousticatalyst.org. Thank you.
