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]
Update on Jan. 14, 2019: A Rocky Mountain National Park spokesman said Monday the park began using recreation fees to temporarily pay about 10 percent of furloughed workers to clean up the park. They’ve been plowing roads, cleaning restrooms and collecting trash since Saturday. Other staff, such as law enforcement rangers, continue to work without pay during the shutdown. The park is expected to reopen to vehicle traffic on Tuesday, said Kyle Patterson, a Park spokesman who is on furlough.
Enos Mills, the main figure behind the creation of Rocky Mountain National Park, enjoyed walking to Lily Lake from his nearby cabin. Wildflowers are common in the spring and early summer.

Other lakes in the Wild Basin include Chasm Lake, Snowbank Lake, Lion Lakes 1 and 2, Thunder Lake, Ouzel Lake, Finch Lake, Bluebird Lake, Pear Lake, and Sandbeach Lake. Many of the lakes have backcountry campsites. Waterfalls include Ouzel Falls, Trio Falls, Copeland Falls, and Calypso Cascades.[47]

The Experience: While news just broke that the old-timey train that travels along the mountainside through Pikes Peak will be closed for repairs for the rest of 2018, the nearby town of Manitou Springs should definitely stay on your bucket list. This resort town, located outside of Colorado Springs, is a true gem, complete with 1000-year-old Anasazi (the Ancestral Puebloans) cliff-dwelling ruins in the Mesa Verde National Park and a Victorian-era castle museum and tea room. Stay at the quaint Holden House bed and breakfast.
Durango - very popular for romantic getaways in Colorado during the summer, and for good reason. The gorgeously restored Main Ave combines Victorian-era Hotels and Wild-West Saloons, giving the city a remarkable atmosphere. There's plenty of scenic drives nearby, and the steam-engine narrow gauge rail journey up to Silverton is a wonderful daytrip.

The montane ecosystem is at the lowest elevations in the park, between 5,600 to 9,500 feet (1,700 to 2,900 m), where the slopes and large meadow valleys support the widest range of plant and animal life,[69][70] including montane forests, grasslands, and shrublands. The area has meandering rivers[70] and during the summer, wildflowers grow in the open meadows. Ponderosa pine trees, grass, shrubs and herbs live on dry, south-facing slopes. North-facing slopes retain moisture better than those that face south. The soil better supports dense populations of trees, like Douglas fir, lodgepole pine, and ponderosa pine. There are also occasional Engelmann spruce and blue spruce trees. Quaking aspens thrive in high-moisture montane soils. Other water-loving small trees like willows, grey alder, and water birch may be found along streams or lakeshores. Water-logged soil in flat montane valleys may be unable to support growth of evergreen forests.[70] The following areas are part of the montane ecosystem: Moraine Park, Horseshoe Park, Kawuneeche Valley, and Upper Beaver Meadows.[70]
The climate change study projects further temperature increases, with greater warming in the summer and higher extreme temperatures by 2050. Due to the increased temperature, there is a projected moderate increase in the rate of water evaporation. Reduced snowfall—perhaps 15% to 30% less than current amounts—and the elimination of surface hail, along with the higher likelihood of intense precipitation events are predicted by 2050. Droughts may be more likely due to increased temperatures, increased evaporation rates, and potential changes in precipitation.[53]

This southwestern mountain town is ideal for multi-sport adventurers who want to have access to activities on land and in the water.

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.

Most visitors to the park drive over the famous Trail Ridge Road, but other roads include Fall River Road and Bear Lake Road.[95] The park is open every day of the year, weather permitting.[96] Due to the extended winter season in higher elevations, Trail Ridge Road between Many Parks Curve and the Colorado River Trailhead is closed much of the year. The road is usually open again by Memorial Day and closes in mid-October, generally after Columbus Day.[93] Fall River Road does not open until about July 4 and closes by, or in, October for vehicular traffic.[97] Snow may also fall in sufficient quantities in higher elevations to require temporary closure of the roads into July,[49][93] which is reported on the road status site.[95]
The Rockies are unbelievable. We explored the Niwot Ridge tundra plateau, speckled with wildflowers of every shape and color, looked down on the layered blue mountain ranges below, while snow-tipped peaks gazed at us from still-greater heights. I felt the elevation only in the difficulty breathing I experienced when walking from Point A to Point B - but we walked for more than three miles. Otherwise, it was the height itself that pulsed through my veins, truly on top of the world.
