If you visit rockslides in alpine country in Alaska you’re likely to see (or hear) Hoary Marmots. These large rodents favor the same kind of habitat as pikas—jumbled sections of granite boulders and scree that provide natural hiding places as well as high points from which to watch for predators. Seeming always to be on the lookout, marmots sound off with a shrill whistling call at the first sign of a threat. Another species, the Alaska Marmot, is found primarily in the Brooks Range.
