Above tree line, at approximately 11,000 ft (3,400 m), trees disappear and the vast alpine tundra takes over.[69] Over one third of the park resides above the tree line, an area which limits plant growth due to the cold climate and strong winds. The few plants that can survive under such extreme conditions are mostly perennials. Many alpine plants are dwarfed at high elevations, though their occasional blossoms may be full-sized.[73]

Brown’s Canyon National Monument – It’s one of Colorado’s newest national monuments, and also one of it’s most beautiful. A pristine, natural canyon, Brown’s Canyon offers visitors the opportunity to hike, raft, or camp in the headwaters of the Arkansas River. Towering ponderosa pine trees and monolithic boulders greet you along this amazing stretch of white water. We may be biased, but we think the best way to see it is by raft. There is also fantastic camping along the river at various locations. Browns’ Canyon is also close to the small town of Nathrop, which offers a number of hot-springs resorts that are perfect for relaxing after a day of adventuring, including Antero Hot Springs Cabins, Mt. Princeton Hot Springs Resort, and Cottonwood Hot Springs.

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]

The montane ecosystem is at the lowest elevations in the park, between 5,600 to 9,500 feet (1,700 to 2,900 m), where the slopes and large meadow valleys support the widest range of plant and animal life,[69][70] including montane forests, grasslands, and shrublands. The area has meandering rivers[70] and during the summer, wildflowers grow in the open meadows. Ponderosa pine trees, grass, shrubs and herbs live on dry, south-facing slopes. North-facing slopes retain moisture better than those that face south. The soil better supports dense populations of trees, like Douglas fir, lodgepole pine, and ponderosa pine. There are also occasional Engelmann spruce and blue spruce trees. Quaking aspens thrive in high-moisture montane soils. Other water-loving small trees like willows, grey alder, and water birch may be found along streams or lakeshores. Water-logged soil in flat montane valleys may be unable to support growth of evergreen forests.[70] The following areas are part of the montane ecosystem: Moraine Park, Horseshoe Park, Kawuneeche Valley, and Upper Beaver Meadows.[70]

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]
Wildflower-lovers are never disappointed in June and July when the meadows and hillsides are splashed with botanical color.

Update on Jan. 14, 2019: A Rocky Mountain National Park spokesman said Monday the park began using recreation fees to temporarily pay about 10 percent of furloughed workers to clean up the park. They’ve been plowing roads, cleaning restrooms and collecting trash since Saturday. Other staff, such as law enforcement rangers, continue to work without pay during the shutdown. The park is expected to reopen to vehicle traffic on Tuesday, said Kyle Patterson, a Park spokesman who is on furlough.
