Magnetic data from the Gunzenhauser Site. Interpretation of the magnetic data indicated the presence of several dipole anomalies in the southern portion of the grid oriented in an east-west direction and another series of dipole anomalies near the center of the grid oriented in a southeast-northwest alignment. While these are probably iron artifacts, their linear orientations suggest their disposal may be something other than random abandonment. In the western center of the grid, there is an area of increased magnetic variation or disturbance. The magnetic anomaly at the eastern edge of this disturbed area is the site datum of rebar and metal fence post. The disturbed area is within the area historically identified as the main portion of the Mormon settlement at Garden Grove.
