Glacial geology in Rocky Mountain National Park can be seen from the mountain peaks to the valley floors. Ice is a powerful sculptor of this natural environment and large masses of moving ice are the most powerful tools. Telltale marks of giant glaciers can be seen all throughout the park. Streams and glaciations during the Quaternary period cut through the older sediment, creating mesa tops and alluvial plains, and revealing the present Rocky Mountains.[61] The glaciation removed as much as 5,000 feet (1,500 m) of sedimentary rocks from earlier inland sea deposits. This erosion exposed the basement rock of the Ancestral Rockies. Evidence of the uplifting and erosion can be found on the way to Rocky Mountain National Park in the hogbacks of the Front Range foothills.[60] Many sedimentary rocks from the Paleozoic and Mesozoic eras exist in the basins surrounding the park.[62] 

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. A perfect opportunity to snag a memorable smooch in the Mile High City — “mile-high club” jokes totally optional. More things to do in Denver >>

Most visitors enter the park through the eastern entrances near Estes Park, which is about 71 miles (114 km) northwest of Denver.[91] The most direct route to Trail Ridge Road is the Beaver Meadows entrance, located just west of Estes Park on U.S. Route 36, which leads to the Beaver Meadows Visitor Center and the park's headquarters. North of the Beaver Meadows entrance station is the Fall River entrance, which also leads to Trail Ridge Road and Old Fall River Road.[91] There are three routes into Estes Park: I-25 to U.S. 34 west which runs alongside the Big Thompson River; U.S. 36 west (northwest) from Boulder connecting to U.S. 34 west; and the Peak to Peak Highway, also known as State Highway 7, from points south.[91]
The park contains a network of trails that range from easy, paved paths suitable for all visitors including those with disabilities, to strenuous mountain trails for experienced, conditioned hikers as well as off-trail routes for backcountry hikes. Most trails are for summer use only, since at other times of the year many trails are not safe due to weather conditions.[82] The park provides dozens of designated backcountry campsites and horseback riding is permitted on most trails.[83] Llamas and other pack animals are also allowed on most of the trails.[84]
Brian and I descended back to ~7,000 feet for dinner in a small-town Indian restaurant in Nederland, Colorado, west of Boulder. By then, both our heads ached like a bad hangover, and my lungs literally burned when I tried to inhale anything but shallow breaths. Add generalized joint pain, and I had a full-blown case of altitude sickness. Given that I am a noted hypochondriac, I expected the worst.
