Archaeologists for Hire: An In-Class Activity Beyond Grades: Capturing Authentic Learning Conference Welcome to the Marveloso Valley, a fictional valley on the central coast of Peru. Over the decades, the Marveloso Valley has been the site to a number of significant archaeological research projects. These projects have not only been ground breaking, but they have also been the instructional lessons in archaeological methods to generations of new students and future archaeologists. A new archaeological firm has recently been formed by Dr. Cage and Dr. Rand. Archaeologists for Hire was going to lead a series of new projects in the Marveloso Valley, focusing on reevaluating the Salado Phase (200 600). Unfortunately, before the two could get started they began to disagree over where exactly to excavate. As a result, the two are excavating separate sites. You are working with Dr. Rand at MARV-39, a hilltop fortress in the middle valley. Stay focused on your work or Dr. Rand s assistant Miss Wing will hurt you. Two excavations units were put within the walled fortress. Unit I is in the fortress s main plaza, Unit II is in a large structure that may have been a residence for a chief. Unit III is located on a residential terrace located below the fortress. Your goal will be to look at the data from one excavation unit to discover what activities were performed in different parts of the site and what they tell us about Salado Phase society. You will also want to look at the stratigraphy of the site to see how society evolved over time. Based on your findings why should Archaeologists for Hire continue research at this site? What do we know about early Andean society? What further research questions could we explore? On profile drawings: Profile drawings show the stratigraphy of a layer. Ideally an archaeologist should draw all four profiles of each unit excavated. The profiles are labeled by the direction that the person drawing that profile is facing; so the northern profile is the profile for the northern edge of the excavation unit. Here are some tips to follow when looking at a drawing of a profile: The grids you see on the drawings usually are measured in meters. The horizontal marks measure the length of the excavation unit from left to right. The vertical measurements measure the depth of an excavation. A length of string is run from one corner of the excavation to the other, and this forms an equator of sort. Depth is measured relative to this 0 marker. It should be noted that you can measure above the 0 marker, if it is placed below the surface. Units from the same sites may not have the stratigraphic sequence. So Layer D in unit 1 may not be the same as layer D in unit 2. So think if the stratigrphaphic sequences for two units do correspond or not. If they don t, does this mean something? Sometimes it does, sometimes it does not.
Glossary Here are some key terms that you may need to understand the descriptions of layers you may have: Bedrock The hard rock surface of a mountain; archaeological soils form on top of bedrock. Camelid An animal that pertains to the family Camelidae, this includes llamas, alpacas, guanacos and vicuñas. Llamas and alpacas can be domesticated or wild. Camelid bones can be associated with herding or hunting. Cervid An animal that pertains to the family cervidae, these are species of deer. In South America deer species were never domesticated and these animals were hunted, usually by groups that had not domesticated llamas and alpacas Hearth An area where a fire is built; in the archaeological record it is identified by a large concentration of ash and burnt soil; fragments of charcoal and other burnt objects are usually found inside a hearth Projectile points Stone tools that have pointed ends and worked edges that are hafted on to the ends of spears and arrows; primarily used for hunting Sand A soil comprised of usually silica dioxide where grain diameter is usually between 2 and 64 mm. Sherd A fragment of a ceramic vessel; or in plainer words, a piece of a pot. Soil A loose sediment comprised of a mixture minerals, ground rock, and organic material that serves as a matrix for archaeological material Sterile soil A soil that is devoid of artifacts and represents the time before people were at a site Wattle and daub A building material made from pressing reeds into mud. Usually used for making walls or roofs.
