Magnetic gradient data from Fort Caspar. The magnetic gradient data contain numerous anomalies. The majority of the anomalies are associated with 20th century disturbances. These include sewer, water, and other utility lines. The irrigation drip system for a row of boundary trees is present in the magnetic data set along with a manhole cover. An abandoned street extends along the south side of the reconstructed Fort Caspar to the west side of the storage shed. A concrete culvert is located adjacent to the abandoned street. The former location of a house is evident at the south end of the grid. While there is an extremely light scatter of magnetic materials across the entire project area, there are three light concentrations in the western half of the project area. Excavations were conducted in the area of the light concentrations near 100N/10E. Two areas near the reconstructed fort in the area between 110N/80E and 140N/160E are relatively dense scatters of magnetic materials or artifacts.
