Precambrian metamorphic rock formed the core of the North American continent during the Precambrian eon 4.5–1 billion years ago. During the Paleozoic era, western North America was submerged beneath a shallow sea, with a seabed composed of limestone and dolomite deposits many kilometers thick.[54] Pikes Peak granite formed during the late Precambrian eon, continuing well into the Paleozoic era, when mass quantities of molten rock flowed, amalgamated, and formed the continents about 1 billion–300 million years ago. Concurrently, in the period from 500–300 million years ago, the region began to sink while lime and mud sediments were deposited in the vacated space. Eroded granite produced sand particles that formed strata—layers of sediment—in the sinking basin.[55]

Cushion plants have long taproots that extend deep into the rocky soil. Their diminutive size, like clumps of moss, limits the effect of harsh winds. Many flowering plants of the tundra have dense hairs on stems and leaves to provide wind protection or red-colored pigments capable of converting the sun's light rays into heat. Some plants take two or more years to form flower buds, which survive the winter below the surface and then open and produce fruit with seeds in the few weeks of summer. Grasses and sedges are common where tundra soil is well-developed.[73]


It may be summertime but Snowmass has returned to the Ice Age with the Snowmass Ice Age Discovery Center that features the most significant Ice Age ecosystem find in Colorado history (and it’s free).

Become immersed in Rocky’s pristine landscape on some of the park’s 355 miles of hiking trails. Choose from flat lakeside walks to steeper, more challenging mountain climbs. The easy .6-mile Bear Lake trail is a popular hike featuring an interpretive nature trail hugging a subalpine lake at the end of Bear Lake Road. For a stunning waterfall hike, make your way to Alberta Falls or Ouzel Falls.
Just outside the towns of Grand Junction and nearby Fruita is Colorado National Monument. A scenic road snakes its way through some outstanding scenery. This is not typical mountain scenery, but a landscape of huge rock spires, cliff walls, canyons, and desert-like surroundings with small trees and scrubby bushes. Most people drive through the monument along Rim Rock Drive and stop at the lookouts that peer over the landscape below. The road is also a popular road biking area, with hearty souls peddling their way up to the lookouts. A number of day hikes access some scenic areas of the monument, most of which involve moderate elevation changes that range from approximately 300 feet to more than 1,000 feet.

The atmosphere is one that combines the charms of a historic mining town with hippy flair. Set at the base of the Rockies, it’s world-renowned for skiing, but in the warmer months, it becomes a top hiking and mountain biking destination, as well as drawing countless visitors for the chance to take once-in-a-lifetime whitewater rafting adventures through the Taylor Canyon. A true mecca for mountain bikers, there are hundreds of miles of trails linked together to create an endless day of touring from Gothic to Mt. Crested Butte, Irwin to Gunnison, or even from Crested Butte all the way to Aspen. If you don’t have a bike, stop by Big Al’s Bicycle Heaven and rent one for the day or for the length of your stay. In addition to riding the trails, you can ride around town and check out all the historic buildings and funky alleyways.

An alpine village peppered with an array of modern resorts, Beaver Creek is the perfect weekend getaway destination. A laid-back ambiance of unhurried travelers, here visitors can get away from it all with the area’s world-class skiing and resort amenities. With gorgeous Rocky Mountain views, Beaver Creek is located in the Vail Valley and offers plenty of activities to fill a weekend itinerary. Many people come to try their hand at the 1,815 acres of skiable slopes, catering to both novice and experts alike. The area has plenty of other things to do, however, as visitors can take in a show at the Vilar Performing Arts Center, or indulge in anything from golf courses to pampering spas, shops and restaurants, with the city even home to a large outdoor ice rink in its city center.
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 two bedrooms, a fully-equipped kitchen (complete with a coffee bean grinder, toaster, and crockpot) and one and a half updated bathrooms, the remote cabin provide luxury accommodations within walking distance of three picturesque mountain lakes. Guests enjoy a range of activities, including hiking, mountain biking, paddle boarding, fly fishing, or exploring the Alta Lakes Ghost Town, or sledding, tubing, ice skating, and more in the winter months.
All this and more just moments from your dream mountain town home.  Or, venture further into Rocky Mountain National Park and nearby high mountain ranges to find scenic drives and trailheads — with wild flower fields, lush basins and snowcapped massifs, world famous hiking, backpacking and mountaineering, pristine trails up bubbling brooks and cascading waterfalls, through chaos canyons to stair-stepping alpine lakes, frozen tarns, imposing glaciers, tantalizing 13’ners and 14,000′ sawtooth ridges — an adventure-filled vacation you’ll always remember.  
In the winter, Steamboat Springs is famous for its champagne powder; in the summertime the Yampa River Valley, Steamboat Lake and Zirkel Wilderness Area become a veritable outdoor wonderland with boat rentals, canoeing, kayaking, fishing, SUP, swimming and camping. The Coca Cola Adventure Zone at the base of Steamboat Ski Resort includes ropes course, slingshot bungee jump, climbing wall, mini-bounce, mechanical bull, human gyro and t-shirt spin art. Bring your bikes and wind along the paved four-mile Yampa River Core Trail that follows the Yampa River. Or better yet, grab a tube and cruise down the only free-flowing river in the state, meaning that nowhere along its 261 miles is it obstructed by dams or diversions (a bonus for those float trips). If you want to warm up (really hot), checkout the natural hot mineral springs at Old Town Hot Springs and Strawberry Park Natural Hot Springs. A not-to-be missed event is Steamboat Springs Pro Rodeo where contestants gather once a week to compete. Once upon a time, my daughter won the Ram Scramble and still raves about it. It’s not every day grabbing a ribbon from a sheep’s rear counts as a win!

The Experience: Hanging Lake in Glenwood Canyon is a summer dream (though it's also incredibly breathtaking in winter when the cascading water freezes). The Colorado River snakes through the center of town, and there's plenty to do outside of this park, making it a lovely destination on its own, but you can also make it a day trip if you're staying in Aspen.

Regardless of whether or not you have seen cliff dwellings before, you will be blown away by Mesa Verde and the amount of access to the actual ruins that the park allows visitors. The park's centerpiece, Cliff Palace is one of the most impressive dwellings in the entire Southwest, with a dramatic setting and incredibly preserved ruins. Ranger-led tours, which run regularly during the summer high season, allow you to climb ladders right up into the heart of the dwelling. If you aren't up for that level of activity, you can get a full view of the site from a nearby overlook.
There is also plenty for you to explore in the surrounding areas. If you head south, you’ll reach Red Rocks Park, which is known for its red rock formations. Head east, and you’ll find yourself in Denver, where you can experience a taste of the city, complete with shopping and dining options. Head west, and you’ll be in the Rocky Mountains, with options to ski.
In winter you can try cross-country skiing and snowmobile trails and after an energetic day out there is nothing better than a soak in one of the natural thermal springs. You can visit the Buena Vista Heritage Museum or go on a Ghost Town adventure, visit several working art studios and galleries, or quench your thirst at a local brewery. Things to Do in Buena Vista
