I’m Sarah Vitak. The echoes of elk bugling reveal the vast high-altitude meadows in Rocky Mountain National Park. From September through October, these male elk are calling for mates. We begin on a cold, rainy night in Moraine Park. The temperature is barely above freezing. A hundred thousand years ago this area’s evergreen-covered ridges … called moraines … were created by rocks left behind by a slow-moving river of ice. A little more than a hundred years ago … due to extensive hunting … there were no elk seen here. At that time … about fifty elk were imported from Yellowstone National Park … and now thousands of elk again find their mates in Colorado’s largest national park. We end in Big Meadows. A bull elk walks through the tall grass and calls into the night … echoing his ancestors … who bugled here for millennia. Sounds of elk in Rocky Mountain National Park … recorded by Jacob Job. Series Producer … Martin Burch. Series Adviser … Ann Marie Awad. Sound Design by Patrick McnameeKing. Music by R. J. Fechter.
