That was not my intention. We planned a trip from Florida to the Rocky Mountains of Colorado for one of my freelance writing projects, and originally scheduled a day in Denver (at 5,280 feet in elevation) to acclimate. Frontier Airlines had a different idea. I heard alternatively that our plane had a mechanical issue, that weather in the Midwest grounded the flight, and that the crew went on strike. Regardless, the airline cancelled our original flight. 

^{If you make the quick jaunt to Denver’s neighbor-to-the-north, start with the Fort Collins Museum of Discovery.  Debuting in November 2012, the museum features over interactive 100 exhibits and activities such as the Music & Sound Lab, where physics, technology, history and hands-on playing and composing lead to inspiration.  The Environmental Learning Center is a 212-acre site comprised of four distinct ecosystems – wetlands, riparian, cottonwood forest and prairie – and offers plenty of programs for kids. The Rocky Mountain Raptor Program takes in injured birds of prey, and welcomes visitors interested in their rehabilitation and release. Want a free ride? The Fort Collins Bike Library loans bicycles to visitors and residents, from one hour to seven days, at no charge.}
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.
^{The Cliff House at Pikes Peak is surprisingly affordable, with additional add-ons that can add a lot to your escape without breaking the bank.

Or you can spring for a bottle or two of sparkling wine or Vista Point Chardonnay. Once you arrive, however, you’ll be blown away at the beautiful accommodations in this elegant late 1800s-style hotel with amazing mountain views, two-person spa tubs and much more. Stay at the hotel for some fine dining, venture into Manitou Springs to take in the beautiful sights or head to nearby Cripple Creek for some casino gambling.

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.

About 300 million years ago, the land was uplifted creating the ancestral Rocky Mountains.[55] Fountain Formation was deposited during the Pennsylvanian period of the Paleozoic era, 290–296 million years ago. Over the next 150 million years, the mountains uplifted, continued to erode, and covered themselves in their own sediment. Wind, gravity, rainwater, snow, and glacial ice eroded the granite mountains over geologic time scales.[56] The Ancestral Rockies were eventually buried under subsequent strata.[57]
^{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 Experience: Denver is the perfect urban adventure for anyone who likes midsize cities. It's easy to navigate and manage and doesn't feel at all claustrophobic, but offers endless cultural excursions, gourmet dining experiences, and a fun nightlife you'd expect from large cities. Make sure you visit the Denver Art Museum, check out the breweries in the RiNo neighborhood, and stay at the Crawford Hotel, which is in the old Denver Union Station. For a boutique hotel, stay at The Maven Hotel.
