Earth Science Honours Field Trip 2004
Late-Cenozoic Evolution of the Walker-Lane Belt


Race track

In spring 2004, the Earth Science honours field trip will visit south-eastern California. Our general goal is to investigate the Late Cenozoic evolution of this region, with topics spanning active tectonics and pluvial/glacial climate history.

    • rain gear/rain hat
    • cold-weather gear sufficient for sitting outside at 0 C: coats, toque, mitts, etc... Max elevation will approach 2750 m (9000ft ), where it will be quite chilly at night.
    • pair of good hiking boots, plus pair of light camp shoes
    • sunblock, SPF>30, good sun hat, long sleeve shirts with collars, light long pants, sunglasses
    • at least two 1 L water bottles.
    • knife,fork, spoon, bowl, cup etc... whatever you require.
    • geology gear : compass, trowel, hand lens, rock hammer, waterproof field book, pocket knife. OPTIONAL: Acid bottle, range finder, GPS (if you have one, please bring it).

    Weather

    We will camp and work at elevations ranging from below sea level to 3000 m, and consequently expect a wide range of temperatures. Eastern California lies in the rain-shadow of two mountain ranges -- the Coast Range and the Sierra Nevada -- and so is generally dry. Without any large water bodies nearby, diurnal temperature swings are large.

    For complete historical and current weather records, check the Western Region Climate Center :  http://www.wrcc.dri.edu/

    Assignments

    Food Group Assignments

    Each food group must do three things, listed below.

    A: Lead a field-stop topic

    Each food group will lead the entire group in a discussion of one of the four following topics:
      • Cima Volcanic Field (CIMAS)

      • Turtlebacks and hourglass canyons of Death Valley (TURTLEBACKERS).

      • Geological Evolution of the Sierra Nevada Range (SIERRA NEVADANS)

      • Geological evolution of Long Valley (LONG VALLEYS)

    The field trip itinerary shows where and when each stop will occur. Be ready!

    In leading the field trip stop, Food Groups should follow this recipe:
      1. The introduction should be prepared at the level of the class (senior undergraduates).
      2. One or two figures should be prepared that are printed or written on poster size paper (something greater than 40 x 40 cm).  This figure can be simply a published figure that you have expanded, or it can be something that the group has made for this trip.  The purpose of the figure(s) is to guide the audience through the important message(s) of your introduction.
      3. The introduction should take between 25 and 35 minutes.  Introductions should provide the following information (minutes):
        • where are we? (Plug and Gosse will provide maps in the field) (2)
        • what is the landform or structure that we should be looking at? (10)
        • what is the genesis of the feature?  How do we know this? (5)
        • what is the age of the feature or events leading to it?  How was it dated? (3)
        • are there any controversies, remaining questions, or interesting results regarding the study of the feature? (5)
        • who did much of the work on the feature (provide a brief  (few minutes) overview of that research) (5)
        • what does this feature tell us about the tectonic history of the Walker Lane Belt and surrounding areas? (5)

    As a helping hand, here is a very good web-page that will help the groups in their pre-trip search. http://gateway.library.uiuc.edu/gex/bibs/deathvalley.html


    B: Integrative reports

    Present integrative written and two 15-minute oral reports on the following two questions on the morning of May 12, before we return to Vegas. Draw from as many examples as possible from observations you have made during the field trip and supplementary literature reviewed before and during the field trip.
    1. Describe the strain dynamics of the Walker Lane by documenting the spatial and temporal variations in strain over Late Cenozoic.
    2. Describe the role and chronology of water (liquid and solid phase) in modifying WLB landscapes during the Pleistocene.

    C: Mapping projects TBA


    Individual Assignments

    Each individual should keep detailed field notes, to be handed in for review at night at major points:
    • April 30, after Mojave and Yucca.

    • May 6, after DV and southern Owens Valley.

    • May 11, after Long Valley, Sierra Nevada glacial history, and Mono Basin.
