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]
Located in in southwestern Colorado, Mesa Verde is home to the famous cliff dwellings of the ancient Anasazi people. It is one of the most significant archeological preserve of Native American culture in the US. In the 12th century, the Anasazi start building houses in shallow caves and under rock overhangs along the canyon walls. The most famous of these is Cliff Palace. The Ancient Puebloans constructed it from sandstone bricks, and mortar made from ash, clay and water. It encompassed 150 rooms and 76 open areas. Climatic change and increased population placed the communities under stress and by the late 1270s, the Ancestral Puebloan population began migrating to what is now New Mexico and Arizona.
The Rockies are unbelievable. We explored the Niwot Ridge tundra plateau, speckled with wildflowers of every shape and color, looked down on the layered blue mountain ranges below, while snow-tipped peaks gazed at us from still-greater heights. I felt the elevation only in the difficulty breathing I experienced when walking from Point A to Point B - but we walked for more than three miles. Otherwise, it was the height itself that pulsed through my veins, truly on top of the world. 
A small city that packs a lot of punch for its size, Vail is one of the most beloved ski destinations in the country, where its not uncommon to spot a celebrity or two.

While most visitors come to Vail for its famous 5,289 acres of ski slopes, in the summer visitors can also explore the Eagles Nest Wilderness Area and Holy Cross Wilderness area to hike the area’s rugged mountainside trails.

Colorado is the perfect destination for an extra-special weekend getaway, especially since it’s home to numerous exciting cities and nature spots. Admire panoramic views of the sweeping, majestic Rocky Mountains, and plan an afternoon hike and picnic. Book a stay at a gorgeous Colorado vacation rental near a historic national park to conveniently enjoy the great outdoors. Here are eight of the most romantic weekend getaway locations in Colorado.
The St. Regis Resort offers castle-like grandeur and a staff that will treat you like royalty. It also has a menu of romantic vacation packages that are perfect for honeymooners, and all can be customized just for you and your new spouse. You can choose things like in-room dining, spa gift certificates for its decadent Remede Spa, as well as having flowers, chocolate-covered strawberries and sparkling wine delivered and waiting in your room upon your arrival. The property sits at the base of Aspen Mountain, just steps away to many of Aspen’s top restaurants and shops. The resort has its own eatery onsite too, which serves breakfast, lunch and dinner as well as hosting live music at night.
The first week of the park shutdown brought little financial impact, said town manager Frank Lancaster, probably because most tourists had already booked their Christmas stays and couldn't cancel. Along the town's main street Wednesday, tourists peered in candy store windows, shopped for T-shirts and rented snowshoes, and there was little sign the nearby park is largely inaccessible.
With over 1,800 acres of skiable terrain in Beaver Creek, it’s no wonder this resort town is a top choice for a weekend trip in Colorado. Beaver Creek is home to the Birds of Prey downhill course, too—a difficult run that’s often included in World Cup races in early December. Not up to the challenge? No worries. There’s plenty more to do like catching a show at the Vilar Performing Arts Center or hanging out at the Beaver Creek Resort. Swing by in the afternoon for a taste of their fresh-baked (and free) chocolate chip cookies.
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]
The Western Slope has plenty of charms, including being a dinosaur mecca with plenty of hands-on science, and is the heart of Colorado’s agricultural region. At the Museum of Western Colorado’s Dinosaur Journey, visitors can get up close and personal with dinosaur skeletons, a working paleontology lab and realistic robotic dinosaurs. Dedicated to “putting science in the hands of kids,” the Western Colorado Math and Science Center features interactive exhibits in biology, physics, earth and space science, and electronics. From June through October, orchards are laden with some of the sweetest harvests around: cherries, grapes, apples, plums, pears, apricots and peaches. Take an orchard tour or check out the myriad of roadside stands selling fresh produce, jams and ciders. For great biking or strolling, the Colorado Riverfront Trail winds for more than 18 miles through the city of Grand Junction’s picnic grounds, botanical garden, protected wetlands and fishing pier. Buy one/get one free passes are available for six major attractions from the Grand Junction Visitors Center. This “Map to Adventure” includes Dinosaur Journey, Museum of the West, Cross Orchards, the John McConnell Math & Science Center, The Art Center and the Western Colorado Botanical Gardens.
When it comes to the best weekend getaways in Colorado, Colorado Springs is a top choice with a little bit of everything—numerous hiking trails, interesting museums, an artsy historic district, and plenty of restaurants and breweries. It’s also home to Garden of the Gods, a National Natural Landmark featuring hiking, climbing, and stunning views at the foot of Pikes Peak.
