Keys Ranch: Where Time Stood Still
National Park Service Teaching with Historic Places U.S. Department of the Interior Keys Ranch: Where Time Stood Still Keys Ranch: Where Time Stood Still (Photo by Harmon and Nelda King, National Park Service) In the high desert of California, flesh-colored boulders rise up out of the stark landscape and embrace a small valley where Keys Ranch stands. Strangely shaped trees cast long shadows on the sides of the simple wooden ranch structures. Animal tracks in the sand tell of the previous night's adventures when scorpions, kangaroo rats, snakes, and bobcats battled for survival. This seemingly hostile desert environment was settled much later than other more productive areas of the West. Yet it was here, in 1917, that Bill Keys chose to establish a ranch and raise a family. Keys and other 20th-century homesteaders lived much as earlier pioneers in the West had, working hard to make their marginal land holdings successful. Today, Keys Ranch is preserved as part of Joshua Tree National Park.

Development of a Dilatant Damage Zone Along a Thrust Relay in a Low-Porosity Quartz Arenite
Journal of Structural Geology 28 (2006) 776–792 www.elsevier.com/locate/jsg Development of a dilatant damage zone along a thrust relay in a low-porosity quartz arenite Jennie E. Cook a, William M. Dunne a,*, Charles M. Onasch b a Department of Earth and Planetary Sciences, University of Tennessee, Knoxville, TN 37996-1410, USA b Department of Geology, Bowling Green State University, Bowling Green, OH 43403, USA Received 12 August 2005; received in revised form 26 January 2006; accepted 15 February 2006 Available online 18 April 2006 Abstract A damage zone along a backthrust fault system in well-cemented quartz arenite in the Alleghanian foreland thrust system consists of a network of NW-dipping thrusts that are linked by multiple higher-order faults and bound a zone of intense extensional fractures and breccias. The damage zone developed at an extensional step-over between two independent, laterally propagating backthrusts. The zone is unusual because it preserves porous brittle fabrics despite formation at O5 km depth. The presence of pervasive, late-stage fault-normal joints in a fault-bounded horse in the northwestern damage zone indicates formation between two near-frictionless faults. This decrease in frictional resistance was likely a result of increased fluid pressure. In addition to physical effects, chemical effects of fluid also influenced damage zone development. Quartz cements, fluid inclusion data, and Fourier Transform Infrared analysis indicate that both aqueous and methane-rich fluids were present within the damage zone at different times. The backthrust network likely acted as a fluid conduit system, bringing methane-rich fluids up from the underlying unit and displacing resident aqueous fluids. -
At Joshua Tree Nafional Park Course Catalog Spring 2018
Desert Institute at Joshua Tree National Park Course Catalog Spring 2018 Welcome to Desert Institute at Joshua Tree National Park It is hard to believe that it was almost 20 years ago that the Joshua Tree National Park Association be- gan a unique experiment to find a way to connect people who were passionate about their park with some of the finest educators in the Southland. The Desert Institute was born to provide the in-depth knowledge that so many of our annual visitors and local residents were clamoring for: day-long classes that go beyond the basics and really immerse the learners in the natural and cultural history that make Joshua Tree such a special place. I remember working here as a journeymen ranger when the first classes were offered back in 1998. That first year, we offered five weekend classes on natural history. Who would have dreamed that twenty years later we would be offering dozens of courses that span the spectrum from desert cooking to smart phone photography to bighorn sheep habitat? One of the exciting new offerings is the Joshua Tree Master Naturalist certificate program. Students who take classes for college credit can also be enrolled in a certification program that is invaluable for educators, naturalists, and guides. What will the next 20 years bring? With your help and feedback, I’m looking forward to this program evolving to continue to meet the changing needs and passions of all of us who are excited to learn about the incredible place we have chosen to call home. -

Joshua Tree National Park, California
I 29.79/3: J 78 General Management Plan Development Concept Plans Environmental Impact Statement PUBLIC DOCI iMENTS DEPO° : "- • '7cM AUG 7 1995 Clliu . *\i LIBRARY JOSHUA TREE National Park • California V ® Printed on Recycled Paper Final General Management Plan Development Concept Plans Environmental Impact Statement Joshua Tree National Park Riverside and San Bernardino Counties, California On October 31, 1994, Public Law 103-433 added 234,000 acres to the Joshua Tree National Monument and changed its status from national monument to national park. The land that was added by the legislation is mainly adjacent to backcountry and wilderness areas. It is largely undeveloped and its management will be addressed in the wilderness and backcountry management plan currently being developed, which will serve as an amendment to this plan. This general management plan addresses only the land that was included prior to the 1994 legislation. This General Management Plan / Development Concept Plans / Environmental Impact Statement was prepared in order to offer a proposal and two alternatives for the management, use, and development of Joshua Tree National Park. In this plan, which affects mainly the developed areas of the park, the proposal calls for a change of management and use to more adequately protect and interpret significant resources. The proposed action would result in an increased visitor awareness of opportunities and a broader range of visitor choices and experiences. Visitor contact facilities and services would be provided at each of the three main park entrances. Interpretive programs and the system of wayside exhibits would be expanded. Resource management programs would also be increased. -
A N–S-Trending Active Extensional Structure, the Fiuhut (Afyon) Graben
Turkish Journal of Earth Sciences (Turkish J. Earth Sci.), Vol. 16, 2007, pp. 391–416. Copyright ©TÜB‹TAK A N–S-trending Active Extensional Structure, the fiuhut (Afyon) Graben: Commencement Age of the Extensional Neotectonic Period in the Isparta Angle, SW Turkey AL‹ KOÇY‹⁄‹T & fiULE DEVEC‹ Middle East Technical University, Department of Geological Engineering, Active Tectonics and Earthquake Research Laboratory, TR–06531 Ankara, Turkey (E-mail: [email protected]) Abstract: The fiuhut graben is an 8–11-km-wide, 24-km-long, N–S-trending, active extensional structure located on the southern shoulder of the Akflehir-Afyon graben, near the apex of the outer Isparta Angle. The fiuhut graben developed on a pre-Upper Pliocene rock assemblage comprising pre-Jurassic metamorphic rocks, Jurassic–Lower Cretaceous platform carbonates, the Lower Miocene–Middle Pliocene Afyon stratovolcanic complex and a fluvio- lacustrine volcano-sedimentary sequence. The eastern margin of the fiuhut graben is dominated by the Afyon volcanics and their well-bedded fluvio- lacustrine sedimentary cover, which is folded into a series of NNE-trending anticlines and synclines. This volcano- sedimentary sequence was deformed during a phase of WNW–ESE contraction, and is overlain with angular unconformity by nearly horizontal Plio–Quaternary graben infill. Palaeostress analyses of slip-plane data recorded in the lowest unit of the modern graben infill and on the marginal active faults indicate that the fiuhut graben has been developing as a result of ENE–WSW extension since the latest Pliocene. The extensional neotectonic period in the Isparta Angle started in the latest Pliocene. All margins of the fiuhut graben are determined and controlled by a series of oblique-slip normal fault sets and isolated fault segments. -
Faults and Joints
97 FAULTS Fractures are planar discontinuities, i.e. interruption of the rock physical continuity, due to stresses. The geological fractures occur at every scale so that any large volume of rock has some or many. These discontinuities are attributed to sudden relaxation of elastic energy stored in the rock. The geological fractures have their economic importance. The loss of continuity in intact rocks provides the necessary permeability for migration and accumulation of fluids such as groundwater and petrol. Fractured reservoirs and aquifers are typically anisotropic since their transmissivity is regulated by the conductive properties of fractures, which the local stress field partially controls. Geological fractures may be partially or wholly healed by the introduction of secondary minerals, often giving rise to ore deposits, or by recrystallization of the original minerals. Planar discontinuities along which rocks lose cohesion during their brittle behavior are: - joints if there is no component of displacement parallel to the plane (there may be some very small orthogonal parting; joints are extension fractures). - faults if rocks on both sides of the plane have moved relative to each other, parallel to the plane (faults are shear fractures). - veins if the fractures are filled with secondary crystallization. Joints and faults divide the rocks into blocks whose size and shape must be taken into consideration for engineering, quarrying, mining, and geomorphology. Fault terminology Definitions Faults separate two adjacent blocks of rock that have moved past each other because of induced stresses. The notion of localized movement leads to two genetically different classes of faults reflecting the two basic behaviors of rocks under stress: brittle and ductile. -

Student Name: Grade: Physical Geology 101 Laboratory Interpreting Geology Maps Introduction & Purpose: The purpose of this laboratory is to gain a working knowledge and skill to read geology maps. Students will learn to read a geology map for the purpose of understanding surface and subsurface structural relations and geologic history that may include a record of rock forming events, mountain building deformation, and the relationship between geology and topography Part I. Review Taking Strike and Dip Directions: Use the Compass and Inclinometer, provided by your instructor, to determine the strike and dip of two inclined boards that are setup in the classroom. Note: Use the boards labeled “X” and “Z”. 1. What is the strike and dip of the board labeled “X” strike: ___________ dip: ________ 2. What is the strike and dip of the board labeled “Z” strike: ___________ dip: ________ Part II – Reading and Interpreting a Simplified Geologic Map Introduction: A geologic map is a greatly scaled-down, two-dimensional abstract representation of the surface geology, structure, and relief of a geographic region of Earth, or even another terrestrial planet. A geologic map typically includes most information found on a topographic map, but most importantly, includes color-coding regions and symbols that denote rock units, contacts, and other structural information. Additionally, all the geologic color-coding and symbols are explained in the legend on a geologic map, including topographic and cardinal information. Directions: The simplified geology map below contains several geologic features that include the following: Sedimentary beds "A", "B", "C", and "D"; Basalt dike" E"; Granite pluton; Fault "Y"; and Unconformity "Z". -
