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.

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] 

You’ll feel really spoiled (especially in Vail!) with complimentary WiFi,  complimentary underground valet parking, free breakfast buffet included a surprisingly hefty selection of pastries, breads, fruits, meats, cheeses, cold cereals, and eggs, as well as juice, tea, and coffee. And the outdoor heated swimming pool is worth taking the plunge just for the view.

Wildflower-lovers are never disappointed in June and July when the meadows and hillsides are splashed with botanical color. Autumn visitors can relax among the golden aspens or enjoy the rowdier antics of the elk rut during mating season. And those brave enough to venture into the cold during the winter are treated to snowscapes unlike any other, as the park is open year-round.

Romantic getaways in Colorado combine sequestered mountain retreats with the cowboy spirit of culture-packed cities like Denver. Set beneath the Rocky Mountains, romantic weekend getaways in Colorado offer the opportunity to see one of America's oldest resort towns, Colorado Springs. Whether you're partying at a festival in idyllic Telluride or hiking through the rock formations of the Garden of the Gods, you'll find it hard not to believe you're in paradise when you're on vacation in Colorado.
Lawn Lake Trail climbs to Lawn Lake and Crystal Lake, one of the parks deepest lakes, in the alpine ecosystem and along the course of the Roaring River. The river shows the massive damage caused by a dam failure in 1982 that claimed the lives of three campers. The trail is a strenuous snowshoe hike in the winter.[42] Ypsilon Lake Trail leads to its namesake as well as Chipmunk Lake, with views of Longs Peak, while traversing pine forests with grouseberry and bearberry bushes. The trail also offers views of the canyon gouged out by rampaging water that broke loose from Lawn Lake Dam in 1982. Visible is the south face of Ypsilon Mountain, with its Y shaped gash rising sharply from the shoreline.[42]
A former Victorian era mining town in the Rocky Mountains, Telluride is a charming town located in a box canyon at the base of a popular ski-and-golf resort. Some of the town’s major attractions include the historic district, which is home to landmarks like the Telluride Historical Museum and the Sheridan Opera House. Telluride is also the site of famous festivals like the Telluride Film Festival and the Telluride Bluegrass Festival.
The park's climate is also affected by the Continental Divide, which runs northwest to southeast through the center of the park atop the high peaks. The Continental Divide creates two distinct climate patterns - one typical of the east side near Estes Park and the other associated with the Grand Lake area on the park's west side.[49] The west side of the park experiences more snow, less wind, and clear cold days during the winter months.[49]
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.
^ Montana State University states in their profile of Rocky Mountain National Park that there has been an increase of 2.5 °F (1.4 °C) in the average park temperature over "the past century" (charts show the period from about 1895-2010).[48] The National Park Service site states that the increase has been 3.4 °F (1.9 °C) over "the last century" (chart shows the period from about 1905-2010).[52]
Garden of the Gods, a registered National Natural Landmark, is a unique landscape of jagged stone towers and fins jutting up 300 feet from the earth, and giant balanced boulders and rock piles dotting the landscape, with distant mountains completing the scene. Fifteen miles of trails, most of which are short and easy, allow you to get up close to the dramatic rock formations and wander through the surreal scenery. The park is a popular area for rock climbing, but other activities in the park include road biking in designated biking lanes, mountain biking, horseback riding, and Jeep and Segway tours.
Rock climbing and mountaineering opportunities include Lumpy Ridge,[85] Hallett Peak, and Longs Peak, the highest peak in the park, with the easiest route being the Keyhole Route. This 8 mi (13 km) one-way climb has an elevation gain of 4,850 ft (1,480 m). The vast east face, including the area known as The Diamond, is home to many classic big wall rock climbing routes. Many of the highest peaks have technical ice and rock routes on them, ranging from short scrambles to long multi-pitch climbs.[86]

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.
