            These workshops in geoarchaeology are aimed at all skill levels in archaeology and geoarchaeology, from beginners who want to learn the basics of soil description to more advanced students wishing to further their skills in a specific geoarchaeological topic.  The goal is to give each student a greater understanding of soils, sediments, and landforms, and to teach the utility of geoarchaeology within archaeology and the wider field of anthropology.  Participants have included undergraduate and graduate students, avocational archaeologists, and academic and contract archaeologists seeking professional development.

            Each workshop is composed of lectures, informal discussions, and field trips to a diverse array of soil exposures.  Enrollments are kept small, usually under 15 students, to facilitate one-on-one communication and instruction.  Lecture, discussion, and field topics can be tailored to individual students and groups, but usually include the following:

- Describing soils in the field and laboratory.
- Interpreting soil horizons and sediment types.
- Bioturbation and other forms of soil mixing.
- Identifying buried soils.
- Soil/sediment/landform relationships.
- The archaeological implications of different sedimentation rates.
- Artifact depth-distribution analysis.
- The use (and misuse) of County Soil Surveys and digital SSURGO soils data. 
- Overview of basic soil sampling and analysis techniques.
- Laboratory analysis methods that do not require elaborate or expensive equipment.
- Incorporating geoarchaeological information into archaeological interpretations.
- Examples of how geoarchaeology has aided in the interpretation of archaeological sites.

            We usually schedule two to three workshops each year (for the 2009 dates watch this website and www.caa-archaeology.org).  If you have a group of six or more people who would like to take the workshop but cannot make these dates, you may be able to arrange a workshop as our schedules permit (call the Center for American Archaeology at 618-653-4316 or e-mail gvogel@caa-archaeology.org).  I am also available at certain times to give talks or workshops (ranging from three hours to two days) to field schools, colleges, universities, professional and avocational groups, or anyone with an interest in geoarchaeology.  Again, please call or e-mail to arrange a meeting that will suit your needs.  
           
            Tuition for the weekend workshop at the Center for American Archaeology is $200, including room (in one of the CAA's bunk-style dormitories) and basic field lunches (breakfast and dinner are not included).  Rooms are often available on the days immediately before and after workshop dates at no additional charge – please contact us to check for availability. 


About the Instructor (Dr. Gregory Vogel)

            I've worked on archaeological and geological projects for more than 17 years, and have taught soils and geoarchaeology in many different contexts.  When I began giving soils talks to field schools and other classes I started writing handouts to help students remember key points – I eventually expanded these and put them together as A Handbook of Soil Description for Archeologists (available for $5 from the Arkansas Archeological Survey here). 

            I teach these workshops from a field-based, practical point of view, concentrating on topics to help archaeologists better describe and interpret soils and sediments, and to understand how geoarchaeology may be incorporated into archaeological projects to great effect, and without a lot of fuss.  The laboratory techniques I cover are all relatively simply and don't require a great deal of time or expensive equipment. 

            Students from many different backgrounds have taken the workshop: undergraduate and graduate college students, professional contract and academic archaeologists, avocationals with an interest in the topic, and students from other Center for American Archeology field schools who stay an extra weekend for the course.  These workshops are a great deal of fun for me, and I always end up learning something from the students: from their backgrounds in archaeology and soils, and from the questions they ask. 

            You can find out more about me and see several on-line projects and papers here.

Searching for buried soils in an alluvial cutbank.  Many characteristics besides color can indicate a buried soil.   

Describing a loess profile in detail.  Students learn the
proper "grammar" of soil description components. 

A question of sediment origins:
clast-supported pebbles and cobbles at the base of a deep loess sequence.

Blue shale weathering into clay that mimics
an in-situ gleyed deposit, demonstrating the
geomorphic principle of equifinality.

Shallow residuum developed into Burlington limestone.  This exposure is rich in chrinoid fossils and both tabular and nodular chert. 

Complex soil/stratigraphic relationships
at the Diehl Sand Pit: multiple depositional
contexts in one exposure.

Bluff-top overview of the Lower Illinois Valley, discussing large-scale landform development.

            What to Bring

            The workshops are hands-on, so bring field clothes as appropriate for the season and conditions.  The soil exposures we visit are all relatively close to the vans (no more than a few hundred meters), but we will still need to walk through tall brush, hop over a creek or two, and climb a moderate slope to get to some of them.  The Lower Illinois Valley can be quite hot and humid during the summer.  For current weather information in the Kampsville area click here. We will be in the field rain or shine, so be sure to bring rain gear.     

            Bring a favorite trowel, shovel, or other implement of excavation if you like, otherwise we will provide them for you.  If you have other soils-related equipment you regularly use in the field (Munsell book, hand-lens, sand-size comparator chart, etc.), feel free to bring these along also. 

            Each workshop covers several "core" ideas in soils and geoarchaeology, but many topics are tailored to the interests of the particular students participating, so be sure to bring material for taking notes during lecture and discussion time.     


A Note on the Background of This Page


(Click for larger image)

            The background image for this page is a stamp set issued by the U.S. Post Office in 2001, illustrating the ecology of the North American Great Plains Prairie (more information from the U.S. Post office here).  I like that the artist (John Dawson) highlighted the importance of soils in the ecosystem.  This scene illustrates several key points in geoarchaeology, including processes through which organic material is incorporated into soil, the bioturbation effects of numerous plants and animals, and an intense thunder shower in the background, no doubt leading to the downward movement of clay and weatherable minerals (an element of "cl" in Hans Jenny's clorpt equation).  Note that Dawson even included an appropriately granular structure in the A horizon!
