  • Mid-Scale Drivers of Variability in Dry Mixed-Conifer Forests of the Mogollon Rim, Arizona

Bowker 3 1 School of Forestry and Ecological Restoration Institute, Northern Arizona University, Flagstaff, AZ 86011, USA; [email protected] 2 Ecological Restoration Institute, Northern Arizona University, Flagstaff, AZ 86011, USA; [email protected] 3 School of Forestry, Northern Arizona University, Flagstaff, AZ 86011, USA; [email protected] * Correspondence: [email protected]; Tel.: +1-928-523-3448 Abstract: The structure and composition of southwestern dry mixed-conifer forests have changed sig- nificantly, decreasing forest resiliency to uncharacteristic disturbances which also threaten ecosystem services. Restoration of these forests can be informed by historical conditions; however, managers and researchers still lack a full understanding of how environmental factors influence forest conditions. We investigated historical and contemporary variability in dry mixed-conifer forests in northern Arizona and identified important environmental drivers. We utilized forest sample plots and den- drochronological reconstruction modelling to describe forest conditions in 1879 and 2014, respectively. We used correlogram analysis to compare spatial autocorrelation of average diameter, basal area and tree density, and structural equation modeling to partition the causal pathways between forest structure, forest composition, and a suite of environmental factors reflecting climate, topography, and soil. Historical (1879) reconstructed forests had significantly fewer trees, lower basal area, and Citation: Jaquette, M.; Sánchez Meador, A.J.; Huffman, D.W.; Bowker, higher average diameter than contemporarily (2014). Composition has shifted from ponderosa M.A. Mid-Scale Drivers of Variability pine dominance towards a more mixed-species composition.

  • A Conceptual Hydrogeologic Model for Fossil Springs, Western
    A CONCEPTUAL HYDROGEOLOGIC MODEL FOR FOSSIL SPRINGS, WESTERN MOGOLLON RIM, ARIZONA: IMPLICATIONS FOR REGIONAL SPRINGS PROCESSES By L. Megan Green A Thesis Submitted in Partial Fulfillment of the Requirements for the Degree of Master of Science in Geology Northern Arizona University May 2008 Approved: _________________________________ Abraham E. Springer, Ph.D., Chair _________________________________ Roderic A. Parnell, Jr., Ph.D. _________________________________ Paul J. Umhoefer, Ph.D. ABSTRACT A CONCEPTUAL HYDROGEOLOGIC MODEL FOR FOSSIL SPRINGS, WEST MOGOLLON MESA, ARIZONA: IMPLICATIONS FOR REGIONAL SPRINGS PROCESSES L. Megan Green Fossil Springs is the largest spring system discharging along the western Mogollon Rim in central Arizona and is a rare and important resource to the region. The purpose of this study was to gain a better understanding of the source of groundwater discharging at Fossil Springs. This was accomplished by (1) constructing a 3-D digital hydrogeologic framework model from available data to depict the subsurface geology of the western Mogollon Rim region and (2) by compiling and interpreting regional structural and geophysical data for Arizona’s central Transition Zone. EarthVision, a 3-D GIS modeling software, was used to construct the framework model. Two end-member models were created; the first was a simple interpolation of the data and the second was a result of geologic interpretations. The second model shows a monocline trending along the Diamond Rim fault. Both models show Fossil Springs discharging at the intersection of the Diamond Rim fault and Fossil Springs fault, at the contact between the Redwall Limestone and Naco Formation. The second objective of this study was a compilation of regional data for Arizona’s central Transition Zone.

  • Timing and Mechanisms of Basement Uplift and Exhumation in the Colorado Plateau–Basin and Range Transition Zone, Virgin Mountain Anticline, Nevada-Arizona
    spe463-14 page 311 The Geological Society of America Special Paper 463 2010 Timing and mechanisms of basement uplift and exhumation in the Colorado Plateau–Basin and Range transition zone, Virgin Mountain anticline, Nevada-Arizona Mark C. Quigley* Department of Geological Sciences, University of Canterbury, Christchurch 8140, New Zealand Karl E. Karlstrom* Department of Earth and Planetary Sciences, University of New Mexico, Albuquerque, New Mexico 87131, USA Shari Kelley* Matt Heizler* New Mexico Institute of Technology, Socorro, New Mexico 87801, USA ABSTRACT Structural, stratigraphic, and thermochronologic studies provide insight into the formation of basement-cored uplifts within the Colorado Plateau–Basin and Range transition zone in the Lake Mead region. Basement lithologic contacts, foliations, and ductile shear zones preserved in the core of the Virgin Mountain anticline parallel the trend of the anticline and are commonly reactivated by brittle fault zones, implying that basement anisotropy exerted a strong infl uence on the uplift geometry of the anti- cline. Potassium feldspar 40Ar/39Ar thermochronology indicates that basement rocks cooled from ≥250–325 °C to ≤150 °C in the Mesoproterozoic and remained at shallow crustal levels (<5–7 km) until they were exhumed to the surface. Apatite fi ssion-track ages and track length measurements reveal a transition from slow cooling beginning at 30–26 Ma to rapid cooling at ca. 17 Ma, which we interpret to mark the change from regional post-Laramide denudational cooling to rapid extension-driven exhu- mational cooling by ca. 17 Ma. Middle Miocene conglomerates (ca. 16–11 Ma) fl anking the anticline contain locally derived basement clasts with ca.

Leighty Arizona Geological Survey Open-File Report 98-22 August, 1998 Arizona Geological Survey 416 W. Congress, Suite 100, Tucson, AZ 85701 Includes 30 page text and 1 :24,000 scale geologic map. This report was supported by the Arizona Radiation Regulatory Agency, with funds provided by the u.s. Environmental Protection Agency through the State Indoor Radon Grant Program, the U.S. Geological Survey via the STATEMAP program, and the Arizona Geological Survey. This report is preliminary and has not been edited or reviewed for conformity with Arizona Geological Survey standards INTRODUCTION The Daisy Mountain Quadrangle, located along the northernmost fringe of the Phoenix metropolitan area, straddles the physiographic boundary between the Basin and Range and Transition Zone (Figure 1). The quadrangle lies between 1-17 and Cave Creek and is bordered on the south by the northwestern end of Paradise Valley and rugged, high-relief terrain of the New River Mountains to the north. The Daisy Mountain Quadrangle includes the community of New River, which is undergoing rapid population growth and is becoming increasingly urbanized. Thus, the knowledge of the distribution and character of bedrock and surficial deposits is important to make informed decisions concerning management of the land and its resources. This project was funded by the Environmental Protection Agency through the State Indoor Radon Grant Program, and the Arizona Geological Survey. PREVIOUS STUDIES Over the last two decades various workers have conducted geologic mapping investigations in the Daisy Mountain Quadrangle.
