Mapping The Landscape For Archaeological Detection, Preservation, And Interpretation: A Case Study In High Resolution Location Modeling From The Blue Mountains Of Northeastern Oregon, Trent Skinner
UNLV Theses, Dissertations, Professional Papers, and Capstones
Archaeological location modeling (ALM) is an important tool in most survey strategies, and has contributed substantially to economizing efforts to locate and characterize the archaeological record. The increasing availability of high resolution (<3m) airborne light detection and ranging (lidar) data has the potential to refine the application and ultimately the role of ALM. This research tests the precision and accuracy gained by incorporating lidar derived data into an ALM. The site records and other environmental data used in this study were all generated over the last four decades by the resource specialists of the Malheur National Forest. The Weights-of-Evidence (WofE) probability method (Bonham-Carter 1994) was used to produce two ALMs; one based on a 10m digital elevation model (DEM) created from satellite imaging, and the second from a 3m resolution lidar derived DEM. Independent variables (e.g., slope, aspect, distance to water, etc.) commonly used in ALM were largely replaced by index variables (e.g., slope position classification, topographic wetness index, etc.). The final models were classified into areas of high, medium, and low archaeological potential, then cross-validated against a reserved random dataset. Models were then compared using the Kvamme gain statistic and site to area frequency ratio. The 3m model demonstrated a significant improvement over the results obtained from the 10m model and the current probability model used in the study area. A number of factors including model resolution, statistical methodology, and the character of the independent and dependent variables all contributed to the increase in precision and accuracy. The incremental improvement in modeling efficiency demonstrated here will create time and cost saving in the management and preservation of cultural resources, and ultimately contribute to a better understanding of patterns of past human land use.

Northeast Historical Archaeology
This article presents a case study on the application of geographical information systems (GIS) in the context of military archaeology at the Fort York National Historic Site (AjGu-26) in Toronto, Ontario. By employing GIS to amalgamate data from historic mapping, ground penetrating radar, LiDAR, and 30 years of archaeological investigation, the authors reconstruct the historic landscape at the central parade ground of this national historic site. In doing so, they identify the remains of an early 19th-century vice-regal building that served as the official residence of the lieutenant governors of Upper Canada before the American forces burned it down in …
A Landscape Of Water And Waste: Heritage Legacies And Environmental Change In The Mesabi Iron Range, John Baeten
A Landscape Of Water And Waste: Heritage Legacies And Environmental Change In The Mesabi Iron Range, John Baeten
Dissertations, Master's Theses and Master's Reports
This dissertation explores the intersection between mining technology, industrial heritage, and environmental history, using iron mining in the Mesabi Range of the Lake Superior Iron District as its core case study. What impact did technological shifts in iron mining and ore processing have on the environment of the Lake Superior basin? How did the environmental changes wrought from low-grade iron ore mining and processing, such as the expansion of open-pits and the production of tailings, affect different communities in Minnesota’s Mesabi Range? And finally, how have the environmental legacies of iron mining been remembered and memorialized, or ignored and forgotten?
