I'm working on a new manuscript that is mainly about an mountain-climbing accident on Mt. McKinley, so I'm often researching Alaska. Recently I found something riveting: a soundscape of Denali National Park.
Here you can click on a map of the park and find out what kind of sound data has been collected at various listening stations. Those marked with large yellow dots include actual recordings of sand hill cranes, howling wolves, bleating sheep, river noise, arctic ground squirrel alerts, and more--even rockfall and an avalanche. You can also listen to mountaineers on the Kahiltna Pass.
