Course Objectives


The objectives of the Summer Presession Courses in Dendrochronology include:

  • Cover basic background of dendrochronology, the study of tree rings
  • Understand features of tree rings that can be measured and used to assess/reconstruct environmental signals and/or to date events of the past
  • Practice the accurate dating of the year of formation of tree rings, using multiple techniques
  • Learn by experience aspects of fieldwork in dendrochronology, including recording field notes electronically
    • Additionally in the field, visit and see first-hand the iconic sites of the Grand Canyon, Sunset Crater, Wupatki, and Montezuma Castle and Well, and learn of their historical significance in the science of dendrochronology
    • Optional: Explore the Sonoran Desert and Sky Islands of Southern Arizona while in Tucson
  • Learn by experience wood shop techniques of preparing dendrochronological specimens for analysis
  • Learn by experience the measurement of ring width and data management and sharing
  • Learn by experience the use of specialty software for analyzing tree-ring data
  • Synthesize replicated dendrochronological data into a defensible interpretation
  • Make short, formal presentations of results to a general audience
  • Specialize in a specific subdiscipline of dendrochronology:
    • Archaeology: Dating of past events of human origin, as well interpreting those events in climatological/ecological contexts
    • Climatology: Modeling modern tree-ring patterns with meteorological data and then reconstructing climatic variability of the past, as well as interpreting high- and low-frequency temporal variability in archaeological/ecological contexts
    • Ecology: Discerning non-climatic signals in tree-ring series that might be ascribable to ecological processes such as fire, insect outbreaks, hillslope positioning, and/or forest management treatments, as well as interpreting ecological events of the past in archaeological/climatological contexts
  • Network with one another, both professionally and personally

What to Bring for Tucson and for Fieldwork
Tucson: Mid May and early June will be hot during the day and mildly warm at night. Click here for local weather, then click on Tucson on the map for 5-day forecast. Note: The LTRR classroom is often kept cooler than preferred, so perhaps bring a sweater to class each day while in Tucson.
  • Academic casual attire will suffice for most activities.
  • Hat and sunglasses highly recommendable.
  • Sunscreen also a good idea for outdoor activities lasting more than an hour.
  • Personal laptop:
    • Martin (LTRR IT) has provided instructions on Wifi access while here.
    • For PCs and Java applets: It's looking like Internet Explorer (IE) is the last browser left still running Java applets, e.g., our applet tool for teaching online how to crossdate by skeleton plotting. Neither Chrome nor Firefox supports applets anymore. Unfortunately, IE runs only on PCs (not Macs). If your laptop is a PC, please have IE installed as a browser, and follow these instructions to enable Java applets:

      1. Click Tools and then Internet Options
      2. Select the Security tab, and select the Custom Level button
      3. Scroll down to Scripting of Java applets (almost the very bottom)
      4. Make sure the Enable radio button is checked
      5. Click OK to save your preference
    • For Macs and Java applets: On recent Macs, Java is not pre-installed or available through Apple, but Java can be downloaded in the usual way from here (the link to do this is clearly displayed on the main page there). Once installed, the built-in web browser on Mac OS, Safari, should be able to run the applet, but, as usual, various security warnings and must be selected to proceed before the applet will appear for the first time. Older Macs had a version of Java provided through the system, but Apple stopped supporting that a while ago.
  • PC vs Mac: DPL software runs for sure on PCs, and probably also on Macs after some work-arounds.
  • Don't forget a thumb drive for easy copying, storing, and sharing of data files.
Tucson after hours: Fieldwork: Northern Arizona and New Mexico will be cooler, with at least some chance of rain.
  • Long clothing (pants and shirt) required for field days
  • Hiking boots required for field days (lighter shoes ok for evening)
  • Hat, sunglasses, and sunscreen essential, maybe a bandana also
  • Cold weather clothing (jacket, gloves, balaclava, raingear), just in case
  • Small daypack
  • Personal water bottles, travel mugs
  • Personal GPS units desired (but not required)
  • Personal increment borer, if you have one
  • Gloves for coring, as preferred
  • Personal Android device, if you have one
  • Personal medications (personal medical issues?)
    • If you have a serious medical condition that requires daily medication, you must (a) inform the instructor in advance of the field trip, and (b) bring at least a 1 week supply of the medication
  • Personal first-aid kit, as desired
  • Insects are not usually a problem in high country of New Mexico and Arizona in late spring. Perhaps the occasional mosquitos at dusk, but ticks are not as bad here as in other places of the US. Long clothes help ward off insects. Still, feel free to bring repellent as desired.
Overnight accommodations in the field:
  • All: Fieldtrip lodging and food expenses will be covered by the Presession fees.
  • Archaeology: Camping gear will be needed for part of this trip, though you'll be at the Merriam-Powell Research Station of Flagstaff for May 23 & 24.
  • Climatology: Motel rooms are reserved for this trip.
  • Ecology: The Ecology class will stay at the Merriam-Powell Research Station of Flagstaff. This station has bunk rooms (pillow and a light blanket are provided, but not linens), showers (bring your own towel), a kitchen, and group amenities. If you have a sleeping bag and can conveniently bring it, please do so. Food and meal planning for this fieldweek will be discussed in class, Friday, May 19.
