The Pierre Shale formation was deposited during the Paleogene and Cretaceous periods about 70 million years ago. The region was covered by a deep sea—the Cretaceous Western Interior Seaway—which deposited massive amounts of shale on the seabed. Both the thick stratum of shale and embedded marine life fossils—including ammonites and skeletons of fish and such marine reptiles as mosasaurs, plesiosaurs, and extinct species of sea turtles, along with rare dinosaur and bird remains—were created during this time period. The area now known as Colorado was eventually transformed from being at the bottom of an ocean to dry land again, giving yield to another fossiliferous rock layer known as the Denver Formation.[58]

Loveland continued its expansions during the 1990’s. In 1990, Yan was contracted to install Loveland’s first fixed-grip quad. The lift serves intermediate and expert bowl terrain to the right of Chair 4. Due to increased skier numbers, in 1995, Loveland decided to enlarge the Basin lodge to its current size. This drastically increased the number of people the building could accommodate. The following year, chair 3 was replaced by a Poma quad chair, doubling the lift capacity at the Valley.

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]

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.

The sun made us lazy, and after following Brian as he made his way upstream I found a wider expanse of sand and gravel, promptly plopping down on a pair of flip flops I had brought in my backpack as a make-shift seat. After identifying the northern harrier hawk over my head, and the savannas sparrows and red-winged blackbirds perched precariously on reeds across the water, I took out my knitting project. I didn’t have to worry about losing Brian; in the valley I could see for miles in both directions.

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]

            “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 Fall River Visitor Center just outside Rocky Mountain National Park is the only one open during the government shutdown. It's run by the Rocky Mountain Conservancy, a non-profit that supports the park. That, plus its location outside the park, and the fact that the Rocky Mountain Conservancy leases the private building are why this visitor center can stay open.

The riparian ecosystem runs through the montane, subalpine, and alpine tundra zones and creates a foundation for life, especially for species that thrive next to streams, rivers, and lakes.[74] The headwaters of the Colorado River, which provides water to many of the southwestern states, are located on the west side of the park. The Fall River, Cache la Poudre River and Big Thompson Rivers are located on the east side of the park. Just like the other ecosystems in the park, the riparian zone is affected by the climatic variables of temperature, precipitation, and elevation. Generally, riparian zones in valleys will have cooler temperatures than communities located on slopes and ridge tops. Depending on elevation, a riparian zone may have more or less precipitation than other riparian zones in the park, with the difference creating a shift in the types of plants and animals found in a specific zone.[75]
