Spiro Micro-Topography Study Spiro Mounds Archeological Park, Spiro, Oklahoma Spiro is one of the most important Mississippian sites in North America. Located in eastern Oklahoma, the site is characterized three types of mounds; one burial mound, two temple mounds, and nine house mounds; ceremonial plazas and supporting city environs. This study focuses on Brown Mound, a temple mound which has been both looted and excavated in the past. A goal of the project was to generate a higher resolution contour map than the existing 25 cm contour interval map shown below. Additional objectives of the project included generation of a five cm resolution digital elevation model (DEM) and creation of a 3D model of the mound. http://www.cast.uark.edu/cast/HARLS/spiro/SpiroMicro.htm
	Alignment Process: Scans were aligned first and then merged. Note the disappearance of the shadows. This is due to the multiple scans taken around the mound.
Scanning Old Main – A Preliminary Assessment Old Main is the oldest building on the University of Arkansas campus. Constructed in 1875, it became the first official University building three years after the University's inception in January of 1872. This redbrick building with a Mansard roof is a beautiful example of 19th century Second Empire style architecture. The south tower has a concave silhouette, while the north tower has an ogee silhouette. On all four sides of the south tower are large round areas designed to be clock faces. These towers were reversed from the original plan so that the "clock tower" would be closer to the city of Fayetteville for better viewing. No clocks were ever installed, however. http://www.cast.uark.edu/cast/HARLS/oldmain/OldMainReport.htm

Archaeological Laser Scanning: New Technologies for the Ancient World Archaeological excavation and preservation are long standing practices with standardized methods, but with new technologies emerging the standards are changing. One new technology, called terrestrial laser scanning, allows for non-invasive, centimeter accurate recording of large scale structures in an x,y,z coordinate system. This non-invasive method is suitable for use on ancient structures and surveying as-built structures. Recently this method was tested on the ruins of Tiwanaku , Bolivia and Macchu Picchu , Peru through a NSF grant for the University of Pennsylvania and the Center for Advanced Spatial Technologies (CAST), University of Arkansas . Researchers were sent to scan these sites to obtain accurate recordings of the structures. These were completed and are being used for archival preservation and to look at new methodologies that can help archaeologists answer age old questions about the site.

Dental Microwear Dental microwear is the study of the microscopic scratches and pits that form on a tooth's surface as the result of its use. Much of the dental microwear research that has been conducted thus far has focused on humans and non-human primates. These can be used as models to reconstruct diets in human ancestors and other fossil primates. http://www.uark.edu/microwear
