Location: Slough Creek Campground Road, Yellowstone National Park
Description: The Junction Butte pack surprised me as I was hiking along the Slough Creek Campround road before dawn. I instantly fell to the ground and began recording. This pack of 8-9 members was about 300-400 yards away, yet their howls were very clear and eerie as they traveled along the winter landscape. Also in the recording, you can hear the calls of Black-Billed Magpies rousing from their roosts and the intermittent sloshing of Slough Creek as the wind bends the sounds across the valley.
Species Present: Gray Wolf (Canis lupus), Black-Billed Magpie (Pica hudsonia)
Recording Equipment: Sound Devices 722 digital audio recorder; Audio-Technica 4022 omnidirectional microphones
