Description
What's that sound? Many rivers in Alaska are fed by melting glaciers. While glaciers melt and move, they grind the earth beneath them into a fine material known as silt. This silt is then deposited into the rivers by glacial meltwater, and thus into rivers like the Yukon. The silt in the Yukon River makes a 'hissing' sound as it passes over rocks and other material in the river, much like how sand or rocks make noise as they slide downhill. NPS/Sean Tevebaugh
