Rising from 7,800 feet to 12,000 – even 14,000 feet in some places – RMNP is a high-elevation park and if you don't give yourself time to adjust to the thinner atmosphere and lower oxygen levels, you could run the risk of getting the headaches, nausea and disorientation characteristic of altitude sickness. Along with taking a day or so to acclimate to the high altitude, you should make sure to consume plenty of water and food to ward off symptoms.

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]
