       Wildflowers along the Black Canyon Trail (Hike 16)

       BIGHORN SHEEP

      The bighorn sheep, Colorado’s official state animal, is also the symbol of Rocky Mountain National Park. It’s estimated that more than six hundred bighorn sheep live in the park, eating grasses and other vegetation and using their grippy hooves and soles to avoid predators by traversing cliffs and ledges. Their horns are permanent and can weigh up to thirty pounds (13.6 kg), and they use them to head-butt each other at speeds of up to 40 miles per hour (64 kmph) in mating rituals. In late spring and early summer, bighorn sheep are known to travel down from the Mummy Range to Sheep Lakes in the middle of the day to get nutrients from the plants and soil.

       BEARS

      Sightings of black bears—whose fur, contrary to their name, can be brown—are uncommon in Rocky Mountain National Park, but enough black bears call the park home for bear canisters to be required for backcountry travel, and for bearproof food lockers to be provided in park campgrounds. Black bears weigh between 200 and 600 pounds, can run 25 to 30 mph, and generally avoid humans.

       MARMOTS

      Cousins of the more famous groundhog, marmots are the huskiest members of the squirrel family, inhabiting rocky areas in the harsh alpine environment and digging labyrinthine tunnel systems underneath boulders, where they live in groups of ten to twenty. They hibernate for more than half the year, bedding down for the winter in late September or early October and staying in until April or May. If you hear a marmot whistle in the alpine, it is likely signaling to other marmots that a potential danger is nearby (you) so they can take cover in tunnels.

       FISH

      Several species of fish can be found in the lakes, rivers, and streams in Rocky Mountain National Park, and six species are known to be native to the park: western longnose sucker, western white sucker, mottled sculpin, cutthroat trout, Colorado River cutthroat trout, and the greenback cutthroat trout, which is the official Colorado state fish and is currently classified as threatened on the endangered species list. All greenback cutthroat trout in Rocky Mountain National Park are catch-and-release.

       WILDFLOWERS

      From late spring to late summer, wildflower blooms bring a palette of red, purple, white, and yellow to trail sides and meadows all over the park. Some of the flowers more commonly seen on the hikes in this book are cow parsnips, arnica, alpine avens, scarlet paintbrush, fireweed, Bigelow’s tansyaster, and lupine. The Colorado state flower, the purpleand-white Colorado columbine, is also found in the park.

       TREES

      Rocky Mountain National Park’s mountainsides are thick with evergreen trees, including Douglas fir, lodgepole pine, ponderosa pine, Colorado blue spruce, and Engelmann spruce, and in the rocky and windiest areas of the park, gnarly limber pines can be found, their trunks and limbs twisted dramatically by wind. Stands of aspen can also be found throughout the park, bringing fall color to the mountains when their leaves turn golden in autumn.

       ALPINE TUNDRA PLANTS

      Above 11,500 feet (3505 m), you won’t see tall trees, but the ground at that altitude is far from barren. Many hardy shrubs, grasses, and lichen thrive in the short growing season and harsh environment of the alpine tundra. Low-growing, wind-twisted fir and spruce trees can be several hundred to a thousand years old. These trees, called Krummholz (a German word meaning “wood that is crooked, twisted, or bent”) mark the upper limit of tree growth and the transition to alpine tundra, where a number of low-to-the-ground grasses and sedges carpet the mountain slopes.
