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]
Rocky Mountain National Park’s 415 square miles encompass and protect spectacular mountain environments. Enjoy Trail Ridge Road – which crests at over 12,000 feet including many overlooks to experience the subalpine and alpine worlds – along with over 300 miles of hiking trails, wildflowers, wildlife, starry nights, and fun times. In a world of superlatives, Rocky is on top!
_{Fishing was a popular pastime for early visitors to the park, and it remains so today, with anglers catching several types of trout, including brown, brook, rainbow and cutthroat. Note: A valid Colorado fishing license is required for all persons 16 years of age or older to fish in Rocky Mountain National Park. For current Colorado fishing license fees visit the Colorado Division of Wildlife website.}
^{The Snow Queen Lodge is a Victorian jewel built during Aspen's Wild West Silver Boom that was later converted to a family-run cozy bed and breakfast. It has nine charming rooms with private baths and tasteful Victorian details and a spacious loft at a different location. The lodge is located in downtown Aspen at the base of Aspen Mountain, walking distance from the gondola, world class skiing, and the free shuttles that will take you to other mountains such as Snowmass, Highlands, or Buttermilk.
Nestled just one mile from the south entrance of Rocky Mountain National Park and two miles from downtown Estes Park, Rockmount Cottages is a 20 cabin resort covering 15 acres of wilderness. On the grounds, you’ll have access to a half mile of the Big Thompson River available for fishing and riverside picnics. To fit the lodge lifestyle, each cabin is constructed of knotty pine and most include cozy, stone fireplaces as well as furnished kitchens, a 40-inch flatscreen and DirecTV, wireless internet, and outdoor charcoal grills and picnic areas.}
Your first stop should be the Quarry Visitors Center from where you can access the main attraction at the park, the Quarry Exhibit Hall, built over the Carnegie Dinosaur Quarry. A huge wall of windows allows in natural light, making it feel more like an excavation site than a museum. Fossils are in various states, from still encased in the stone wall to fully assembled skeletons.
Take in the beautiful scenery of Colorado's Front Range, the gateway to Rocky Mountain National Park, as you zip through the trees! Just a 30-minute drive from downtown Denver lie three of Colorado’s longest zipline tracks. 6-line Zipline: Enjoy 4 hours of fresh air, scenic views and thrills on the 6-line zipline in the Rocky Mountains. Ride on six lines that range from 850 feet (259 m) to 1,900 feet (579 m). Soar through the treetops and experience three of Colorado’s longest ziplines! There is a 10-minute uphill hike between the first and second zipline and minimal walking between the others; above-average physical condition is recommended.
The charming town of Boulder is surrounded by dramatic scenery, including the amazing Flatirons, acres of forest and snow-capped peaks – a perfect year-round playground. You can soak up the atmosphere on historic Pearl Street before hiking deep into Flatiron territory from the Open Space Mountain Park or meander through the town along Boulder Creek Path.
_{Known as a world-class ski destination, Aspen is beautiful year around and offers activities and attractions for all ages. Skiers can challenge their skills on the magnificent steeps, slopes and glades of Aspen Mountain or Ajax, on rugged Aspen Highlands or enormous Snowmass. Take a 14 minute ride with the Silver Queen Gondola to the top of Ajax Mountain for the spectacular views of the mountain peaks, the city below and tall evergreens all around you. There are bluegrass concerts on Sundays.}

Lulu City, Dutchtown, and Gaskill in the Never Summer Mountains were established in the 1870s when prospectors came in search of gold and silver.[19] The boom ended by 1883 with miners deserting their claims.[20] The railroad reached Lyons, Colorado in 1881 and the Big Thompson Canyon Road—a section of U.S. Route 34 from Loveland to Estes Park—was completed in 1904.[21] The 1920s saw a boom in building lodges and roads in the park, culminating with the construction of Trail Ridge Road to Fall River Pass between 1929 and 1932, then to Grand Lake by 1938.[22]

Hands down, Crested Butte is my favorite summer destination in Colorado. In addition to world-famous mountain biking and hiking (the views from Snodgrass Mountain are second-to-none), don’t miss the four-week long Crested Butte Music Festival (with the free Divine Family Young People’s Concert July 13, 20 and Aug. 3) and the Wildflower Festival (July 8-14, 2013) where you’ll swear you climbed onto a Monet canvas of mad, extravagant colors. Last winter, CBMR purchased the Coke Zero Gravity BagJump; a 50 feet by 50 feet bag of air for guests to tube and ski and ride into. Come summer, the resort will be setting up two levels of scaffolding at 10 feet and 20 feet for kids and adults alike to jump into the cloud-like bag of air. The resort will also be building a dirt jump for biking enthusiasts to practice their jumping skills with their bicycles for an added adrenaline rush, as if the 25 miles of trails in the Evolution Bike Park isn’t enough. For younger kids, check-out the Trailhead Children’s Museum and big kids (must weigh at least 70 pounds) can try the Crested Butte Zipline Tour, which includes five zip lines ranging in length from 120 – 400 feet connected by features or “events” such as suspended wood bridges and towering platforms. P.S. A few years ago, my kids did Kids Nature Camp at world-renown Rocky Mountain Biological Laboratory in nearby Gothic, Colo. and still rave about it.
Brian eventually caught one small trout in the Moraine creek - success! - and many more in the other rivers that flowed through the park, both that afternoon and the next day. We gazed at fellow monoliths from the top of tundra trails, and spooked a red fox along a riverway. All the time, my small knitting project lay safe and secure in my pack, ready to emerge anytime we sat for more than a few moments.
For mountain bikers, Colorado is a haven, with great trails all over the state. Unfortunately, the mountain climate limits the season in many areas. But the town of Fruita, near Grand Junction, has the climate to enable you to stretch out your mountain biking season through the shoulder seasons and into the winter months. It's also a quirky little town with enough character to make you want to stay a while and return.
