“We were on par for a good year but after the closure, we pretty much stopped. We didn’t hit our targets,” said Zach Zehr, manager at the Estes Park Mountain Shop who’s now pushing backcountry ski adventures. “People either cut their trips short or they were pure cancellations because they heard it was closed. Or they didn’t recreate as they thought they would. They shifted gears and did something else. They didn’t buy hats and gloves because they weren’t going to use them.”

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]

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.

The road is usually open from Memorial Day until early October. However, the park is open year-round and lower elevation roads are open during the winter.
“The law is clear: if the federal government is shut down, our National Parks must also be closed to protect public safety and pristine spaces. It is not acceptable to use FLREA (Federal Lands Recreation Enhancement Act) funds to keep the parks open, and the Department of the Interior’s actions likely violate appropriations law,” McCollum said in a statement.
Founded in 1859, Breckenridge is a historic town that rose in popularity for its fantastic ski resorts.

The park is home to some 2,000 to 3,000 elk in summer, and between 800 and 1,000 elk spend the winter within its boundaries. Because of lack of predation, the National Park Service culls around 50 elk each winter. Overgrazing by elk has become a major problem in the park's riparian areas, so much so that the NPS fences them out of many critical wetland habitats to let willows and aspens grow. The program seems to be working, as the deciduous wetland plants thrive within the fencing. Many people think the elk herd is too large, but are reluctant to reintroduce predators because of its proximity to large human populations and ranches.[76]

Rocky Mountain National Park was selected to participate in a climate change study, along with two other National Park Service areas in the Rocky Mountain region and three in the Appalachian Mountain region.[50] The study began in 2011, orchestrated by members of the academic scientific community in cooperation with the National Park Service and the National Aeronautics and Space Administration (NASA).[50] The stated objective: "develop and apply decision support tools that use NASA and other data and models to assess vulnerability of ecosystems and species to climate and land use change and evaluate management options."[51]

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.

A geographical anomaly is found along the slopes of the Never Summer Mountains where the Continental Divide forms a horseshoe–shaped bend for about 6 miles (9.7 km), heading from south–to–north but then curving sharply southward and westward out of the park.[5][27] The sharp bend results in streams on the eastern slopes of the range joining the headwaters of the Colorado River that flow south and west, eventually reaching the Pacific.[5][28] Meanwhile, streams on the western slopes join rivers that flow north and then east and south, eventually reaching the Atlantic.[5][28]
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.

Putting my Rocky Mountain inspired rectangles away until February, I eventually knitted up the remaining pieces and ironed the whole thing out before I framed the simple square and placed it on my beige wall. Perhaps I needed the chill of winter to remind me of the brisk breeze of that famous mountain range, maybe I briefly tired of sweater and cardigan projects, captivated instead by the simplicity of knit-purl in straight lines.

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]
