At about 68 million years ago, the Front Range began to rise again due to the Laramide orogeny in the west.[58][59] During the Cenozoic era, block uplift formed the present Rocky Mountains. The geologic composition of Rocky Mountain National Park was also affected by deformation and erosion during that era. The uplift disrupted the older drainage patterns and created the present drainage patterns.[60]
Colorado’s biggest city, Denver offers an eclectic mix of attractions, from its trendy eateries to its impressive museums. A combination of a cityscape and natural surroundings, Denver is more than just a base to explore Colorado’s other outdoor treasures.

Spend a day at the Denver Art Museum, Denver Museum of Nature & Science or the Denver Zoo, then browse Larimer Square and catch a game at Coors Field.
Sleep helped the altitude sickness, and after a full night in one of the research site’s cabins, I felt much revived. Brian fished in the morning and I scrambled up a rocky outcropping with a graduate student studying pikas through their poop (a non-invasive way to analyze stress levels of this small mammal that looks like a cross between a rabbit and a mouse): but our afternoon was free. What to do?
Just a few miles from the town of Estes Park, Rocky Mountain National Park is one of the most popular national parks in the United States. The soaring mountain peaks, alpine lakes and meadows, forests, and abundant wildlife showcase nature at its best. The park has more than 100 peaks over 10,000 feet, including Longs Peak, the highest in the park, at 14,259 feet.
This southwestern mountain town is ideal for multi-sport adventurers who want to have access to activities on land and in the water. The Animas River snakes right through Durango and is famous for providing some of the best kayaking and rafting in the state. Head just uphill, and you can be surrounded by the soaring peaks of the Rockies, hiking in out-of-this-world alpine terrain, while the lowlands offer outstanding mountain biking on over 1,000 miles of trails in the Durango area alone. One of the must-dos, no matter when you’re here, is to hop aboard the historic Durango & Silverton Narrow Gauge Railroad, a narrow gauge steam train built specifically built to handle the narrow mountain routes, chugging along at 18 miles per hour as it climbs the steep and magnificent mountain passes between Durango and Silverton. Much of its downtown area is a designated National Historic District and offers a number of interesting places to visit, like the San Juan County Historical Society, housed in the old county jail, as well as the Mayflower Gold Mill National Historic Site and the Old Hundred Gold Mine.
The first week of the park shutdown brought little financial impact, said town manager Frank Lancaster, probably because most tourists had already booked their Christmas stays and couldn't cancel. Along the town's main street Wednesday, tourists peered in candy store windows, shopped for T-shirts and rented snowshoes, and there was little sign the nearby park is largely inaccessible.

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]
The sun made us lazy, and after following Brian as he made his way upstream I found a wider expanse of sand and gravel, promptly plopping down on a pair of flip flops I had brought in my backpack as a make-shift seat. After identifying the northern harrier hawk over my head, and the savannas sparrows and red-winged blackbirds perched precariously on reeds across the water, I took out my knitting project. I didn’t have to worry about losing Brian; in the valley I could see for miles in both directions.
