Bull Elk
From mighty elk to rare boreal toads, Rocky Mountain National Park protects animals of the high south-central continental divide. Elk number about 1000 in the park, and are easily seen. Moose are more rare, found primarily in the Kawaneeche valley. Bighorn sheep are fond of coming to mineral licks in Horseshoe Park. Mountain lions are fairly common, but as is also true of bobcats, secretive and rarely seen. Black bears thrive in the parks lower forests. Hardy ptarmigan remain active at higher elevations through the winter, as do pikas. Ptarmigan, snowshoe hares, and ermine blend with the season, whitening in winter. Marmots and ground squirrels sleep deeply then, but are easily seen during the summer. Greenback Cutthroat Trout have been restored to many lakes and streams, where they feed on a rich insect fauna.
