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 may be accessed through Estes Park or via the western entrance at Grand Lake. Trail Ridge Road, also known as U.S. Route 34, connects the eastern and western sides of the park.[91] The park has a total of five visitor centers. The Alpine Visitor Center is located in the tundra environment along Trail Ridge Road, while Beaver Meadows and Fall River are both near Estes Park, with Kawuneeche in the Grand Lake area, and the Moraine Park Discovery Center near the Beaver Meadows entrance and visitor center.[9]
Experience the high country the old fashioned way — atop a horse. This is a wonderful way for older children to see more alpine country than possible on foot. There are two stables located within the park: Glacier Creek Stables and Moraine Park Stables. 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.
While sightseeing in Denver, be sure to note your elevation: One of the steps in front of the Colorado State Capitol building is marked with a plaque signifying that it is exactly 5,280 feet, or one mile, above sea level.

Such weather will only last for a few hours to a day, but if you are planning to cross over Trail Ridge Road, weather may hamper your travel.

Rising from 7,800 feet to 12,000 – even 14,000 feet in some places – RMNP is a high-elevation park and if you don't give yourself time to adjust to the thinner atmosphere and lower oxygen levels, you could run the risk of getting the headaches, nausea and disorientation characteristic of altitude sickness. Along with taking a day or so to acclimate to the high altitude, you should make sure to consume plenty of water and food to ward off symptoms.

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. In the winter, the trail around the lake is often suitable for walking in boots, or as a short snowshoe or ski. 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]
“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.”

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]

Situated in Southern Colorado, the Great Sand Dunes National Park is an impressive sight.

At 265,000 acres, Rocky Mountain National Park isn't the country's largest national park, nor is it the most-frequented with about 4 million annual visitors (compared to Great Smoky Mountains National Park's more than 11 million visitors). But there is something definitively magical about RMNP, which rises 12,183 feet into the Colorado sky. The main attraction is hiking its 350-some miles of trails that wind through pine and spruce forests, glittering alpine lakes, swaths of wildflowers and if you're lucky, some elk or bighorn sheep. And maybe it's the thinner atmosphere that goes to visitors' heads, but even the most jaded report feelings of awe and wonder after a day or two of breathing in that refreshing mountain air.
