The Pierre Shale formation was deposited during the Paleogene and Cretaceous periods about 70 million years ago. The region was covered by a deep sea—the Cretaceous Western Interior Seaway—which deposited massive amounts of shale on the seabed. Both the thick stratum of shale and embedded marine life fossils—including ammonites and skeletons of fish and such marine reptiles as mosasaurs, plesiosaurs, and extinct species of sea turtles, along with rare dinosaur and bird remains—were created during this time period. The area now known as Colorado was eventually transformed from being at the bottom of an ocean to dry land again, giving yield to another fossiliferous rock layer known as the Denver Formation.[58]
The park is home to many predatory animals, including Canadian lynx, foxes, bobcat, cougar, black bear, and coyotes. Wolves and grizzly bears were extirpated in the early 1900s. Most of these predators kill smaller animals, but mountain lions and coyotes kill deer and occasionally elk. Bears also eat larger prey. Moose have no predators in the park. Black bears are relatively uncommon in the park, numbering only 24-35 animals. They also have fewer cubs and the bears seem skinnier than they do in most areas.[79] Canadian lynx are quite rare within the park, and they have probably spread north from the San Juan Mountains, where they were reintroduced in 1999. Cougars feed mainly on mule deer in the park, and live 10–13 years. Cougar territories can be as large as 500 square miles.[80] Coyotes hunt both alone and in pairs, but occasionally hunt in packs. They mainly feed on rodents but occasionally bring down larger animals, including deer, and especially fawns and elk calves. Scat studies in Moraine Park showed that their primary foods were deer and rodents. They form strong family bonds and are very vocal.[81]
Vail is one of the world’s most popular ski resort towns, but in the warmer months of the year, it draws visitors who come to mountain bike, hike, golf and ride whitewater rapids. Throughout the season, there are an abundance of music and dance festivals, including the Bravo! Vail Valley Music Festival which features orchestras like the New York Philharmonic that performs at the outdoor Gerald R. Ford Amphitheater, as well as the Vail International Dance Festival and the Vail Jazz Festival. Just a few of the other highlights include botanical tours through the Betty Ford Alpine Gardens, rock climbing excursions in Vail Valley and the wealth of shops, bars and eateries in the village of Vail itself. 
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.

Approximately 260 miles of trails are open to horse use, which makes up more than 70 percent of the total trail network in the park.
I am convinced Chautauqua is Colorado’s best-kept secret and I’m amazed how few locals know about its charms. Located at the base of the Flatirons in Boulder, this National Historic Landmark has rental cottages that are surrounded on three sides with open space that includes 48 miles of hiking trails and thousands of acres of natural lands begging to be explored. On weekends in June, Theatre-Hikes Colorado will take audience members on a moderate hike amidst the scenic backdrop of Boulder Open Space while scenes from “Snow White” are performed along the way. On June 29, don’t miss the Colorado Music Festival’s Young People’s Concert, which is a is a narrated work about a cartoon score being performed at a symphony concert (tickets are $8). The historic Chautauqua Dining Hall (a tradition since 1898) has recently undergone a huge overhaul and the wraparound porch offers some of the best patio dining in Colorado. If you visit on a Saturday, be sure to also visit the Boulder’s Farmer’s Market (the largest in Colorado). Not to be forgotten are Pearl Street Mall’s restaurants, shops, people-watching and Pop Jet Fountain–they never fail to entertain.

Offering visitors a glimpse into Colorado’s rich history, Georgetown is a charming Victorian mining town nestled just west of Denver. Once the third-largest city in the state, Georgetown was built in 1884 to service the silver mines. Visitors can take a ride on the famous Georgetown Loop Railroad to Silver Plume and back, or visit the well-preserved Hotel de Paris to browse artifacts from the era. Learn how the wealthy locals used to live at the Hamill House Museum or simply browse the charming streets lined with Victorian-era homes and shops. Those who want to explore the area by car should drive along the Guanella Pass, a long stretch of road with picturesque views, before taking rest in one of the area’s many Victorian bed and breakfast inns.
The recreational activities are what draw most people to Maroon Bells. The hiking here is incredible, with all kinds of day hikes and backpacking areas. Mountain biking trails cover hundreds of miles. Fishing in lakes, ponds, rivers, and streams is popular in summer. In winter, people come here to ski, snowshoe, and snowmobile, making it a year-round outdoor playground.
Dinosaur National Monument is so diverse that the possibilities here extend well beyond the archeological aspects, from a simple driving tour through the monument to hiking, fishing, rafting, and camping. A number of scenic drives run through the park on both paved and four-wheel drive roads. Hiking trails range from short nature walks of less than a half mile to eight-mile-long day hikes. Campgrounds, some of which are open to both tents and RVs and others open only to tents, are spread around the park. It's possible to spend a few days in this area if you are interested in exploring the park.
Brown’s Canyon National Monument – It’s one of Colorado’s newest national monuments, and also one of it’s most beautiful. A pristine, natural canyon, Brown’s Canyon offers visitors the opportunity to hike, raft, or camp in the headwaters of the Arkansas River. Towering ponderosa pine trees and monolithic boulders greet you along this amazing stretch of white water. We may be biased, but we think the best way to see it is by raft. There is also fantastic camping along the river at various locations. Browns’ Canyon is also close to the small town of Nathrop, which offers a number of hot-springs resorts that are perfect for relaxing after a day of adventuring, including Antero Hot Springs Cabins, Mt. Princeton Hot Springs Resort, and Cottonwood Hot Springs.
Estes Park vacation rentals are always worth considering, but be sure to check the calendar before you book and you could enjoy something even more special.

The park's climate is also affected by the Continental Divide, which runs northwest to southeast through the center of the park atop the high peaks. The Continental Divide creates two distinct climate patterns - one typical of the east side near Estes Park and the other associated with the Grand Lake area on the park's west side.[49] The west side of the park experiences more snow, less wind, and clear cold days during the winter months.[49] 
Dinosaur National Monument, in northwest Colorado, combines dramatic scenery with natural and cultural history to create one of Colorado's most interesting sites. Dinosaur remains embedded in exposed rock walls reveal evidence of the giants that once roamed these areas. Petroglyphs offer insight into the cultures and people that lived here long ago, and surrounding it all are cliff walls and the Green and Yampa Rivers snaking through the otherwise dry landscape.
While it is possible to travel through Rocky Mountain National Park and not catch sight of any wildlife, we venture to say that is an unlikely experience. From everyday sightings of chipmunks and mule deer to the moving experience of viewing elk in rut (the mating season), the animals in the park let you know that you are part of something truly wild. Some of these critters are harder to spot than others - they might camouflage themselves in the trees or hide in the underbrush - but look closely and you may have an encounter unlike any other.
