Precambrian metamorphic rock formed the core of the North American continent during the Precambrian eon 4.5–1 billion years ago. During the Paleozoic era, western North America was submerged beneath a shallow sea, with a seabed composed of limestone and dolomite deposits many kilometers thick.[54] Pikes Peak granite formed during the late Precambrian eon, continuing well into the Paleozoic era, when mass quantities of molten rock flowed, amalgamated, and formed the continents about 1 billion–300 million years ago. Concurrently, in the period from 500–300 million years ago, the region began to sink while lime and mud sediments were deposited in the vacated space. Eroded granite produced sand particles that formed strata—layers of sediment—in the sinking basin.[55]

The park was designated a World Biosphere Reserve by the United Nations in 1976 to protect its natural resources.[67][68] The park's biodiversity includes afforestation and reforestation, ecology, inland bodies of water, and mammals, while its ecosystems are managed for nature conservation, environmental education and public recreation purposes.[67] The areas of research and monitoring include ungulate ecology and management, high-altitude revegetation, global change, acid precipitation effects, and aquatic ecology and management.[67]

Putting my Rocky Mountain inspired rectangles away until February, I eventually knitted up the remaining pieces and ironed the whole thing out before I framed the simple square and placed it on my beige wall. Perhaps I needed the chill of winter to remind me of the brisk breeze of that famous mountain range, maybe I briefly tired of sweater and cardigan projects, captivated instead by the simplicity of knit-purl in straight lines.

            “By 1900, the growing national conservation and preservation movement, led by Theodore Roosevelt, Gifford Pinchot, and John Muir, advocated an appreciation for nature. The Estes Park Protective and Improvement Association fostered local conservation efforts. "Those who pull flowers up by the roots will be condemned by all worthy people," they warned. In 1909, Enos Mills, a naturalist, nature guide, and lodge owner, championed the creation of the nation's tenth national park. He hoped that: "In years to come when I am asleep beneath the pines, thousands of families will find rest and hope in this park." Unleashing his diverse talents and inexhaustible energy, he spent several years lecturing across the nation, writing thousands of letters and articles, and lobbying Congress to create a new national park. Most civic leaders supported the idea, as did the Denver Chamber of Commerce and the Colorado Mountain Club. In general, mining, logging, and agricultural interests opposed it. On January 26, 1915, President Woodrow Wilson signed the Rocky Mountain National Park Act.”
The climate change study projects further temperature increases, with greater warming in the summer and higher extreme temperatures by 2050. Due to the increased temperature, there is a projected moderate increase in the rate of water evaporation. Reduced snowfall—perhaps 15% to 30% less than current amounts—and the elimination of surface hail, along with the higher likelihood of intense precipitation events are predicted by 2050. Droughts may be more likely due to increased temperatures, increased evaporation rates, and potential changes in precipitation.[53]

At 265,000 acres, Rocky Mountain National Park isn't the country's largest national park, nor is it the most-frequented with about 4 million annual visitors (compared to Great Smoky Mountains National Park's more than 11 million visitors). But there is something definitively magical about RMNP, which rises 12,183 feet into the Colorado sky. The main attraction is hiking its 350-some miles of trails that wind through pine and spruce forests, glittering alpine lakes, swaths of wildflowers and if you're lucky, some elk or bighorn sheep.

The uplift disrupted the older drainage patterns and created the present drainage patterns.[60]
