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]

At 14,115 feet in elevation, Pikes Peak, in Pike National Forest, is one of the Southwest's famous "fourteeners," a reference to mountains that stand over 14,000 feet. The snow-capped peak is easily recognizable from the nearby town of Colorado Springs. This is one of the most visited mountains in the world, second only to Mt. Fuji. Unlike many mountain peaks that are inaccessible to the average person, you can drive to the summit of Pikes Peak on the Pikes Peak Highway, off highway 24, west of Colorado Springs. Travel time is about 1.5 hours. Alternatively, you can take the Pikes Peak Cog Railway for a scenic 8.9-mile trip, with a round-trip time of just over three hours.


Fort Collins is the perfect base camp for your trip, located just 35 miles from the peaks of Rocky Mountain National Park that soar to more than 13,000 feet and form the Continental Divide. The town of Estes Park sits at the eastern edge of the park. Rocky Mountain National Park covers 410 square miles and includes Longs Peak (14,255 feet high), 18 named peaks above 13,000 feet, 150 named lakes, and the highest continuously paved highway in the U.S. — Trail Ridge Road. The road is usually open from Memorial Day until early October. However, the park is open year-round and lower elevation roads are open during the winter.

Cache La Poudre River trail begins north of Poudre Lake on the west side of the valley near Milner Pass and heads downward toward the Mummy Pass trail junction. Lake Irene is a recreation and picnic area.[40]

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]
