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] 
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]

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.
