Pike Texas Tech University, James Daniel Pike, August 2017 ACKNOWLEDGMENTS I would like to extend my greatest thanks to my advisor Dr. Dustin Sweet, who was an excellent advisor during this research. Dr. Sweet was vital throughout the whole process, be it answering questions, giving feedback on figures, and imparting his extensive knowledge of the ancestral Rocky Mountains on me; for this I am extremely grateful. Dr. Sweet allowed me to conduct my own research without looking over my shoulder, but was always available when needed. When I needed a push, Dr. Sweet provided it. I would like to thank my committee memebers, Dr. Lee and Dr. Lehman for providing feedback and for their unique perspectives. I would like to thank Jenna Hessert, Trent Jackson, and Khaled Chowdhury for acting as my field assistants. Their help in taking measurements, collecting samples, recording GPS coordinates, and providing unique perspectives was invaluable. Thank you to Melanie Barnes for allowing me to use her lab, and putting up with the mess I made. This research was made possible by a grant provided by the Colorado Scientific Society, and a scholarship provided by East Texas Geological Society.

Geology of the Park Program Welcome! We look forward to sharing the geological story of Garden of the Gods with your students. We align with current Colorado Academic Standards for K-5 Earth and Space Science. Goals: Students recognize the exceptional geological wonder of the Garden of the Gods. Students gain a broad understanding of the geological events that shaped the Pikes Peak region Students gain a broad understanding of and appreciation for the science of geology. Students identify the three rock types and the three geological processes. Students recognize the geological formations in the Park, their ages, and composition. 1 Teacher Reference Guide: Basic Geology of Garden of the Gods The Pike’s Peak region has been shaped by millions of years of mountain building and erosion. There have been three different mountain building events in the geological history of this area: 1. The Ancestral Rockies (320-310 million years ago). The erosion of these first Rocky Mountains formed the sedimentary Fountain Formation and the Lyons Sandstone layers. 2. The Laramide Orogeny (70-65 million years ago). This process uplifted the Front Range. The layers seen in the Garden were forced upright as the land broke along the Rampart Range Fault.

  • Mesozoic Stratigraphy at Durango, Colorado
    160 New Mexico Geological Society, 56th Field Conference Guidebook, Geology of the Chama Basin, 2005, p. 160-169. LUCAS AND HECKERT MESOZOIC STRATIGRAPHY AT DURANGO, COLORADO SPENCER G. LUCAS AND ANDREW B. HECKERT New Mexico Museum of Natural History and Science, 1801 Mountain Rd. NW, Albuquerque, NM 87104 ABSTRACT.—A nearly 3-km-thick section of Mesozoic sedimentary rocks is exposed at Durango, Colorado. This section con- sists of Upper Triassic, Middle-Upper Jurassic and Cretaceous strata that well record the geological history of southwestern Colorado during much of the Mesozoic. At Durango, Upper Triassic strata of the Chinle Group are ~ 300 m of red beds deposited in mostly fluvial paleoenvironments. Overlying Middle-Upper Jurassic strata of the San Rafael Group are ~ 300 m thick and consist of eolian sandstone, salina limestone and siltstone/sandstone deposited on an arid coastal plain. The Upper Jurassic Morrison Formation is ~ 187 m thick and consists of sandstone and mudstone deposited in fluvial environments. The only Lower Cretaceous strata at Durango are fluvial sandstone and conglomerate of the Burro Canyon Formation. Most of the overlying Upper Cretaceous section (Dakota, Mancos, Mesaverde, Lewis, Fruitland and Kirtland units) represents deposition in and along the western margin of the Western Interior seaway during Cenomanian-Campanian time. Volcaniclastic strata of the overlying McDermott Formation are the youngest Mesozoic strata at Durango. INTRODUCTION Durango, Colorado, sits in the Animas River Valley on the northern flank of the San Juan Basin and in the southern foothills of the San Juan and La Plata Mountains. Beginning at the northern end of the city, and extending to the southern end of town (from north of Animas City Mountain to just south of Smelter Moun- tain), the Animas River cuts in an essentially downdip direction through a homoclinal Mesozoic section of sedimentary rocks about 3 km thick (Figs.
