About 300 million years ago, the land was uplifted creating the ancestral Rocky Mountains.[55] Fountain Formation was deposited during the Pennsylvanian period of the Paleozoic era, 290–296 million years ago. Over the next 150 million years, the mountains uplifted, continued to erode, and covered themselves in their own sediment. Wind, gravity, rainwater, snow, and glacial ice eroded the granite mountains over geologic time scales.[56] The Ancestral Rockies were eventually buried under subsequent strata.[57]
The town of Dolores may be small, but it’s well-worth spending some time in, tucked in a magnificent canyon with the picturesque Dolores River cutting along one side and rock cliffs on the other. The second largest reservoir, McPhee Reservoir, can be found here, and San Juan National Forest, just a mile from town, provides excellent opportunities for fly fishing, hiking, and biking. In addition to outdoor activities, the town boasts four parks, a brewpub and a unique mix of restaurants and shops.
The Experience: Hanging Lake in Glenwood Canyon is a summer dream (though it's also incredibly breathtaking in winter when the cascading water freezes). The Colorado River snakes through the center of town, and there's plenty to do outside of this park, making it a lovely destination on its own, but you can also make it a day trip if you're staying in Aspen.
A geographical anomaly is found along the slopes of the Never Summer Mountains where the Continental Divide forms a horseshoe–shaped bend for about 6 miles (9.7 km), heading from south–to–north but then curving sharply southward and westward out of the park.[5][27] The sharp bend results in streams on the eastern slopes of the range joining the headwaters of the Colorado River that flow south and west, eventually reaching the Pacific.[5][28] Meanwhile, streams on the western slopes join rivers that flow north and then east and south, eventually reaching the Atlantic.[5][28]

There are four ecosystems, or zones, in Rocky Mountain National Park: montane, subalpine, alpine tundra, and riparian. The riparian zone occurs throughout all of the three other zones. Each individual ecosystem is composed of organisms interacting with one other and with their surrounding environment. Living organisms (biotic), along with the dead organic matter they produce, and the abiotic (non-living) environment that impacts those living organisms (water, weather, rocks, and landscape) are all members of an ecosystem.[66]

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]
By day, this forested hot spring just north of Steamboat Springs teems with families splashing in the all-natural pools.

As of 2010, the preceding one hundred years of records indicated an increase in the average annual temperature of approximately 3 °F (1.7 °C).[48][52][a] The average low temperature has increased more than the average high temperature during the same time period.[48] As a result of the temperature increase, snow is melting from the mountains earlier in the year, leading to drier summers and probably to an earlier, longer fire season.[48] Since the 1990s, mountain pine beetles have reproduced more rapidly and have not died off at their previous mortality rate during the winter months. Consequently, the increased beetle population has led to an increased rate of tree mortality in the park.[53]
