Airborne electromagnetic and magnetic survey, western Hualapai Indian Reservation near Grand Canyon West and Peach Springs, Arizona, 2018
Airborne electromagnetic (AEM) and magnetic survey data were collected during March 2018 along 1,637 line line-kilometers over the western Hualapai Indian Reservation and surrounding areas. The survey was conducted as part of a study of the groundwater resources of the Truxton basin and Hualapai Plateau. The survey was designed to improve the understanding of the geometry of the major hydrostratigraphic contacts of the study area. Data were acquired by SkyTEM ApS with the SkyTEM 312 time-domain helicopter-borne electromagnetic system together with a Geometrics G822A cesium vapor magnetometer. The survey was flown at a nominal flight height of 30 meters (m) above terrain along block-style lines with a nominal spacing of 1 kilometer (km) over the Truxton Basin and 4 km over the Hualapai Plateau. Due to terrain complexity, the mean flight height was about 53 m. The AEM depth of investigation varies with subsurface resistivity, typical maximum depth of investigation occurs between 150 and 600 m. This data release includes minimally processed (raw) AEM and magnetic data, fully processed AEM data used for resistivity model development, and 32-layer laterally constrained inverted resistivity models.

The area surrounding the Grand Canyon has spectacular outcrop exposure in the modern canyon walls, leading to stratigraphic contact delineations that are well constrained near canyons yet poorly constrained where the terrain remains undissected and relatively unexplored by boreholes.
