Escondido Pueblo (FB9569)

Magnetic gradiometry survey results. Faint hints of linear features are evident throughout, most likely adobe walls of enhanced magnetic susceptibility		Close up view of a likely burned structure found with the magnetic instrument		Filtered magnetic susceptibility data reveals linear trends possibly representing structures and garden plots
Magnetic susceptibility data revealing linear trends possible representing structures and garden plots		Circular trends appear in the unprocessed conductivity data possibly representing adobe pitstructures		Close-up of conductivity data and GPR data showing an adobe structure. Adobe, which is highly conductive is represented by black. Why does the entire roomblock visible in GPR (made of adobe) not appear in conductivity?
Filtered GPR data enhances the linear alignments of room blocks at a depth of .25 to .5 m		Close up view of structures found with the GPR		Color composite simultaneously displays ground penetrating radar (tinted red), soil conductivity (green) magnetic susceptibility (blue) results through GIS produced transparent overlays
