Zach Zehr, an avid backcountry adventurer, spends a lot of time in Rocky Mountain National Park, which is open but operating with a limited staff since Dec. 22, 2018, due to the federal government shutdown. Because of the shutdown, the roads aren’t being plowed so much of the park is not open to vehicle traffic. Fat bikes, however, work just fine. Zehr, who is also the manager at the Estes Park Mountain Shop, and some friends rode their fat bikes to the Bear Lake Trailhead and did a backcountry ski trip in the park on Jan. 6, 2019.

The history of Rocky Mountain National Park began when Paleo-Indians traveled along what is now Trail Ridge Road to hunt and forage for food.[11][12] Ute and Arapaho people subsequently hunted and camped in the area.[13][14] In 1820, the Long Expedition, led by Stephen H. Long for whom Longs Peak was named, approached the Rockies via the Platte River.[15][16] Settlers began arriving in the mid-1800s,[17] displacing the Native Americans who mostly left the area voluntarily by 1860,[18] while others were removed to reservations by 1878.[14]

The Rockies are unbelievable. We explored the Niwot Ridge tundra plateau, speckled with wildflowers of every shape and color, looked down on the layered blue mountain ranges below, while snow-tipped peaks gazed at us from still-greater heights. I felt the elevation only in the difficulty breathing I experienced when walking from Point A to Point B - but we walked for more than three miles. Otherwise, it was the height itself that pulsed through my veins, truly on top of the world.

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 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]
