Surface geophysical data from Ollalie North springs, west-central Oregon

Surface electrical resistivity tomography (ERT) data were collected in September of 2018 near Ollalie North springs in the upper McKenzie River watershed of west-central Oregon. ERT data were acquired along a single transect on the north bank of Ollalie Creek using a combination of inverse Schlumberger, dipole-dipole, and Wenner arrays. These data were collected to contribute high-resolution subsurface information about the geologic structure and distribution of groundwater near high-discharge springs in the Oregon High Cascades. This data release includes the raw resistivity data, inverted resistivity models, and locational information.
