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]
The best time to visit Rocky Mountain National Park is from June to September when the snow is (mostly) melted and the hiking trails and attractions are accessible. Still, these four months are also the most popular times to visit, so if you'd rather experience RMNP in relative isolation and while wearing snowshoes or cross-country skis, visit between the months of October and May. Whether snow or sunshine, the park is open to the public 24 hours a day, 365 days a year, though some parts may be inaccessible. 

Remnants of Breckenridge's history as a mining hub give the town an aesthetic that is simply darling. Couple that with the Rocky Mountains that serve as the town's backdrop and you've got a ski destination for the books. When the powder melts, the verdant vegetation that floods the trails make Breck (as locals call it) magical. What's more, the beer scene is an attraction in its own right. Read More »


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). Touch a mastodon tooth, marvel at a half-sized 6-foot Wooden Mammoth Skeleton, do a dig of your own or a daily Ice Age Discovery Hike by  Environment Studies.  Visit the Snowmass Rodeo on Wednesday nights (June 12- August 28) and sign up your kids for the Calf Scramble and Mutton Busting. Ride the Elk Camp Gondola up Snowmass Mountain where the Elk Camp Restaurant will open for activities including downhill biking, dinner, campfires, live music, movies, Stryder Park and Kid’s Playground on Friday evenings. Try your hand at some slopeside bowling at the new bowling alley below Venga Venga Cantina featuring eight full-sized lanes, a lounge area with full bar, wood-fired oven pizzas, upscale bar food and more. Then, get inspired at the Anderson Ranch Arts Center, a stellar place for kids of all ages to take workshops that include sculpture, photography, painting, beading, and mask-making.

More than 3,000 elk, 800 bighorn sheep and herds of mule deer and moose live in the park. For the best photography lighting and opportunities to spot massive bugling elk, head to Moraine Park just after sunrise. View bighorn sheep at Sheep Lakes May through mid-August and catch a glimpse of RMNP’s ever-elusive moose population along the Colorado River in the Kawuneeche Valley on the park's west side.
Rocky Mountain National Park is one of the highest national parks in the nation, with elevations from 7,860 to 14,259 feet (2,396 to 4,346 m),[30] the highest point of which is Longs Peak.[31] Trail Ridge Road is the highest paved through-road in the country, with a peak elevation of 12,183 feet (3,713 m).[32] Sixty mountain peaks over 12,000 feet (3,658 m) high provide scenic vistas.[30] On the north side of the park, the Mummy Range contains a number of thirteener peaks, including Hagues Peak, Mummy Mountain, Fairchild Mountain, Ypsilon Mountain, and Mount Chiquita.[33] Several small glaciers and permanent snowfields are found in the high mountain cirques.[34]
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.

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.
