Non-flowering lichens cling to rocks and soil. Their enclosed algal cells can photosynthesize at any temperature above 32 degrees Fahrenheit (0 °C), and the outer fungal layers can absorb more than their own weight in water. Adaptations for survival amidst drying winds and cold temperatures may make tundra vegetation seem very hardy, but in some respects it remains very fragile. Footsteps can destroy tundra plants and it may take hundreds of years to recover.[73] Mammals that live on the alpine tundra, or visit during the summer season, include bighorn sheep, elk, badgers, pikas, yellow-bellied marmots, and snowshoe hares. Birds include prairie falcons, white-tailed ptarmigans, and common ravens. Flowering plants include mertensia, sky pilot, alpine sunflowers, alpine dwarf columbine, and alpine forget-me-not. Grasses include kobresia, spike trisetum, spreading wheatgrass, and tufted hairgrass.[73]

The mountain biking trails around Fruita are some of the top-rated trails in the state. Most notably are the 18 Road Trails, with the infamous Zippity Do Da trail, and the Kokopelli Loops. This is desert terrain, with trails that run along the tops of ridges and everywhere in between or alongside cliff ledges with views over the Colorado River. This area has, for many mountain bikers, become an alternative to Moab, Utah. During the spring, you can even combine sports; mountain biking in Fruita one day and skiing at Beaver Creek or Vail - just over two hours away - the next.

Rocky Mountain National Park is home to many species of animals, including nearly 70 mammals and almost 300 species of birds. This diversity is due to the park's varying topography, which creates a variety of habitats. However, some species have been extirpated from the park, including the gray wolf, the wolverine, the grizzly bear, and the American bison.
Rocky Mountain National Park is an American national park located approximately 76 mi (122 km) northwest of Denver International Airport[4] in north-central Colorado, within the Front Range of the Rocky Mountains. The park is situated between the towns of Estes Park to the east and Grand Lake to the west. The eastern and westerns slopes of the Continental Divide run directly through the center of the park with the headwaters of the Colorado River located in the park's northwestern region.[5] The main features of the park include mountains, alpine lakes and a wide variety of wildlife within various climates and environments, from wooded forests to mountain tundra.
Glacial geology in Rocky Mountain National Park can be seen from the mountain peaks to the valley floors. Ice is a powerful sculptor of this natural environment and large masses of moving ice are the most powerful tools. Telltale marks of giant glaciers can be seen all throughout the park. Streams and glaciations during the Quaternary period cut through the older sediment, creating mesa tops and alluvial plains, and revealing the present Rocky Mountains.[61] The glaciation removed as much as 5,000 feet (1,500 m) of sedimentary rocks from earlier inland sea deposits. This erosion exposed the basement rock of the Ancestral Rockies. Evidence of the uplifting and erosion can be found on the way to Rocky Mountain National Park in the hogbacks of the Front Range foothills.[60] Many sedimentary rocks from the Paleozoic and Mesozoic eras exist in the basins surrounding the park.[62]
With many peaks and granite rock formations, there are lots of rock climbing opportunities. Some favorite climbs include the aptly-named Lumpy Ridge and Longs Peak. Whether you prefer bouldering, mountaineering, rock climbing, or ice climbing, the park has something for climbers of all levels. In the winter, opportunities for snowshoeing, skiing, and sledding draw all levels of explorers. If you're in the western part of the park, visit Grand Lake. This breathtaking lake is the state's largest natural body of water, promising scenic views and plenty of outdoor fun. 
If you're looking to splurge during ski season, Aspen is the place to be. This small town is conveniently tucked between four renowned ski spots that offer quality slopes for all levels of skiers. Not only that, but the town features the crème de la crème of luxury resorts that whip up an après-ski scene so appealing it'll be pretty tough to leave. Read More »

^{Reminiscent of the grand mountain lodges built at the turn of the 20th century, the Wild Horse Inn is handcrafted from 400-year old logs and moss covered rock, and it boasts grandiose windows that look out over the valley. This beautifully rustic inn is the perfect winter escape with luxurious log cabin rooms, crackling fireplaces, en-suite bathrooms with showers and jetted tubs, and private balconies or decks. Guests are treated to a full gourmet breakfast each morning and can enjoy complimentary tea, coffee, hot chocolate, and cookies all day.
At about 68 million years ago, the Front Range began to rise again due to the Laramide orogeny in the west.[58][59] During the Cenozoic era, block uplift formed the present Rocky Mountains. The geologic composition of Rocky Mountain National Park was also affected by deformation and erosion during that era. The uplift disrupted the older drainage patterns and created the present drainage patterns.[60]}

In the shadow of Great Sand Dunes National Park and Pre­serve, the quirky town of Hooper sits atop a natural artesian hot spring, with water flowing year-round into the family-friendly Sand Dunes Pool. On the same property, The Greenhouse is an all-indoor, all-adult oasis with three small soaking tubs and a 10-by-75-foot zero-entry pool. The Greenhouse also has a 10-person sauna, indoor gardens and an onsite bar to help you stay even toastier.  

The park contains a network of trails that range from easy, paved paths suitable for all visitors including those with disabilities, to strenuous mountain trails for experienced, conditioned hikers as well as off-trail routes for backcountry hikes. Most trails are for summer use only, since at other times of the year many trails are not safe due to weather conditions.[82] The park provides dozens of designated backcountry campsites and horseback riding is permitted on most trails.[83] Llamas and other pack animals are also allowed on most of the trails.[84]
Above tree line, at approximately 11,000 ft (3,400 m), trees disappear and the vast alpine tundra takes over.[69] Over one third of the park resides above the tree line, an area which limits plant growth due to the cold climate and strong winds. The few plants that can survive under such extreme conditions are mostly perennials. Many alpine plants are dwarfed at high elevations, though their occasional blossoms may be full-sized.[73]
