Electrical Resistivity Tomography (ERT) data files collected near Quitobaquito Spring in Organ Pipe Cactus National Monument, 2023 and 2024

Direct-Current resistivity data were collected to characterize the hydrogeology and groundwater depth surrounding Quitobaquito Spring. Resistivity data are sensitive to water-content in the geologic unit in the subsurface. DC resistivity data were collected at six transects. One transect passes just south of the spring pool and runs east-west. One transect is located just southeast of the spring and runs east-west through a sandy wash that experience surface flow during high precipitation in the area. One transect cross potential faults as it runs southwest-northeast and is located northwest of the spring. One transect crosses directly over the spring discharge site and runs roughly north-south. One transect travels from the spring to the northeast rising along the elevation of the nearby hill. The final transect runs north-south through the sandy wash located east of the spring. This data includes the raw data and inverted resistivity models.
