Mt. Olympus, mythological home of the Greek gods, Yosemite’s Half Dome, the ever-classic Matterhorn, Alaska’s Denali, and Colorado’s Pikes Peak all share the quality of compelling attraction that a charismatic alpine profile evokes. At the base of our peak along the confluence of two small, nondescript streams, Native Americans gathered thousands of years ago. Explorers, immigrants, city-visionaries and fortune-seekers arrived successively, all shaping in turn the region and communities that today spread from the flanks of Pikes Peak. From any vantage point along the Interstate 25 corridor, the Colorado plains, or the Arkansas River Valley escarpments, Pikes Peak looms as the dominant feature of a diverse “bioregion”, a geographical area with a distinct flora and fauna, that stretches from alpine tundra to desert grasslands. “Biodiversity” is shorthand for biological diversity: a term covering a broad array of contexts from the genetics of individual organisms to ecosystem interactions. The news tells us daily of ongoing threats from the loss of biodiversity on global and regional levels as humans extend their influence across the face of the earth and into its sustaining processes. On a regional level, biologists look for measures of biodiversity, celebrate when they find sites where those measures are high and mourn when they diminish; conservation organizations and in some cases, legal statutes, try to protect biodiversity, and communities often struggle to balance human needs for social infrastructure with desirable elements of the natural landscape.

  • Denudation History and Internal Structure of the Front Range and Wet Mountains, Colorado, Based on Apatite-Fission-Track Thermoc
    NEW MEXICO BUREAU OF GEOLOGY & MINERAL RESOURCES, BULLETIN 160, 2004 41 Denudation history and internal structure of the Front Range and Wet Mountains, Colorado, based on apatite­fission­track thermochronology 1 2 1Department of Earth and Environmental Science, New Mexico Institute of Mining and Technology, Socorro, NM 87801Shari A. Kelley and Charles E. Chapin 2New Mexico Bureau of Geology and Mineral Resources, New Mexico Institute of Mining and Technology, Socorro, NM 87801 Abstract An apatite fission­track (AFT) partial annealing zone (PAZ) that developed during Late Cretaceous time provides a structural datum for addressing questions concerning the timing and magnitude of denudation, as well as the structural style of Laramide deformation, in the Front Range and Wet Mountains of Colorado. AFT cooling ages are also used to estimate the magnitude and sense of dis­ placement across faults and to differentiate between exhumation and fault­generated topography. AFT ages at low elevationX along the eastern margin of the southern Front Range between Golden and Colorado Springs are from 100 to 270 Ma, and the mean track lengths are short (10–12.5 µm). Old AFT ages (> 100 Ma) are also found along the western margin of the Front Range along the Elkhorn thrust fault. In contrast AFT ages of 45–75 Ma and relatively long mean track lengths (12.5–14 µm) are common in the interior of the range. The AFT ages generally decrease across northwest­trending faults toward the center of the range. The base of a fossil PAZ, which separates AFT cooling ages of 45– 70 Ma at low elevations from AFT ages > 100 Ma at higher elevations, is exposed on the south side of Pikes Peak, on Mt.

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.

    THE GEOCHEMICAL AND MINERALOGICAL EVOLUTION OF THE MOUNT ROSA COMPLEX, EL PASO COUNTY, COLORADO, USA by Philip Persson A thesis submitted to the Faculty and Board of Trustees of the Colorado School of Mines in partial fulfillment of the requirements for the degree of Master of Science (Geology). Golden, Colorado Date ________________ Signed: ________________________ Philip Persson Signed: ________________________ Dr. Katharina Pfaff Thesis Advisor Golden, Colorado Date ________________ Signed: ________________________ Dr. M. Stephen Enders Professor and Interim Head Department of Geology and Geological Engineering ii ABSTRACT The ~1.08 Ga Pikes Peak Batholith is a type example of an anorogenic (A)-type granite and hosts numerous late-stage sodic and potassic plutons, including the peraluminous to peralkaline Mount Rosa Complex (MRC), located ~15 km west of the City of Colorado Springs in Central Colorado. The MRC is composed of Pikes Peak biotite granite, fayalite-bearing quartz syenite, granitic dikes, Mount Rosa Na-Fe amphibole granite, mafic dikes ranging from diabase to diorite, and numerous rare earth (REE) and other high field strength element (HFSE; e.g. Th, Zr, Nb) rich Niobium-Yttrrium-Fluorine (NYF)-type pegmatites. The aim of this study is to trace the magmatic evolution of the Mount Rosa Complex in order to understand the relationship between peraluminous and peralkaline rock units and concomitant HFSE enrichment and mineralization processes. Field work, petrography, SEM-based methods, whole rock geochemistry, and electron probe micro-analysis (EPMA) of micas was performed on all rock units to determine their textural, mineralogical and geochemical characteristics. Early peraluminous units such as the Pikes Peak biotite granite and fayalite-bearing quartz syenite contain annite-siderophyllite micas with high Fe/(Fe + Mg) ratios, and show relatively minor enrichments in REE and other HFSE compared to primitive mantle.

  • Petrology and Mineralogy of the Mount Rosa Area, El Paso and Teller Counties, Colorado
    THE AMERICAN MINERALOGIST, VOL. 5 1, MARCH-APRIL, 1966 PETROLOGY AND MINERALOGY OF THE MOUNT ROSA AREA, EL PASO AND TELLER COUNTIES, COLORADO. II. PEGMATITESI EuceNB B. Gnoss, CaliJornia Diris,ion of Mines and Geology San Fra nci sco, C alifor n i o AND E. Wu. IIerNnrcu, Department of Geologyand Mineralogy The Llniversity of Michigan, Ann Arbor, Michigan. Aesrnlcr Two contrasting swarms of pegmatite dikes occur intermingled in the Pikes Peak granite and in related alkalic granites in the Mount Rosa area, west of Colorado Springs. One is the older calc-alkalic Pikes Peak type; the younger is the alkalic Mount Rosa type. The accessory assemblage of the Mount Rosa quartz-microcline-riebeckite pegmatites consists chiefly of radioactive zircon, fluorite, astrophyllite, thorite, and lesser amounts of pyrochlore, rutile, niobian rutile, columbite, bertrandite and rare aluminofluorides. These dikes intrude both the Pikes Peak and its derivative fayaiite granites along north- east-trending fractures. These pegmatites contrast markedly with the coexisting Pikes Peak pegmatites, which are characterized by quartz and amazonite crystals, zircon, biotite, siderite, and minor topaz, allanite, cassiterite and genthelvite. The Pikes Peak type occurs as segregations and injected bodies only within Pikes Peak granite. Age determinations on zircons from pegmatites of the Mount Rosa type proved to be inconsistent, but ages determined by means of the Kao/Ara0 method on pegmatitic rie- beckite are consistent rvith geological evidence and age determinations on the granites, giving an age of 1040 my. INrnolucrroN Discoverl' of unusual minerals in pegmatitesof the St. Peters Dome district, Mount Rosa area,Colorado, attracted the attention of mineralo- gists as earlv as 1877 (Koenig, 1877).

  • Evolution of the Crystallisation Conditions in the Wellington Lake Pegmatite in the Pikes Peak Granite, Colorado (USA)

This work is distributed under the Creative Commons Attribution 4.0 License. Evolution of the crystallisation conditions in the Wellington Lake Pegmatite in the Pikes Peak Granite, Colorado (USA) Ludmila Maria Fonseca Teixeira, Julien Allaz, and Olivier Bachmann Institute of Geochemistry and Petrology, Eidgenössische Technische Hochschule (ETHZ), Zürich, Switzerland Pegmatites are texturally, mineralogically, and geochemically zoned rocks that show distinctive features such as graphic granite in the wall zones, coarse-crystalline material in the centre, and unusual mineralisation sometimes of economic significance. They are usually considered to be derived from silicate melts, but a significant fluid supply is also required to reproduce their unique - - 2- 3- characteristics. These fluids are commonly enriched in flux anions such as F , Cl , CO3 , and BO3 . Many studies have investigated the petrogenetic processes that led to pegmatite crystallisation, yet not all aspects of pegmatite formation have been fully understood. Notably, the nature of the precipitating medium remains uncertain for the different zones of the pegmatite. In order to better understand the transition from a silicate-melt-dominated crystallisation to fluid-dominated precipitation, we aimed to produce a temperature profile across the pegmatite and its host granite. We analysed quartz crystals from the different zones of the Wellington Lake Pegmatite and the host rock, a syenogranite of the Pikes Peak Batholith, in Colorado (USA). This NYF-type pegmatite consists of a fine-grained graphic granite wall zone, a coarse-grained quartz and albite intermediate zone, and pure blocky quartz core zone with REE-dominated mineralisation including fluocerite, bastnäsite, thorite, columbite, zircon, and cassiterite.

  • Catamount Ranch Open Space Forest Stewardship Management Plan
    Catamount Ranch Open Space Forest Stewardship Management Plan Colorado State Forest Service Teller County Division of Parks November, 2000 _____________________________________________________________________________________ Catamount Ranch Open Space Forest Stewardship Management Plan Page 1 Purpose In July of 1998 Teller County adopted the Management Plan for the Catamount Ranch Open Space, a document providing general goals and objectives for the next five years. The Planning Team agreed to the following vision statement: The Catamount Ranch Open Space will be managed primarily for long- term natural resource conservation and will remain commercially undeveloped. The Planning Team decided that the vision statement should be complemented by a set of broad principles that would govern Catamount Ranch Open Space. The principles are more specific than the ideas expressed in the vision statement and apply generally to the entire Open Space. The list of operating principles is as follows: • The Catamount Ranch Open Space will be essentially undeveloped and managed primarily for long-term, natural resource conservation. • Secondarily, management will provide opportunities for people to enjoy and learn about the land, the wildlife, and the history of the area while respecting the primary purpose of long-term resource conservation through limited access and low-key human impact. • Management of the Catamount Ranch Open Space will respect the neighbors and complement adjoining land uses. • Management will use wise and prudent practices that minimize negative impacts on the land, flora, and fauna that might arise from public use of the property. The Planning Team also developed a list of goals and objectives for the Open Space. The goals are the desired outcome of management on the property.
