The U.S. Geological Survey collected low-altitude airborne natural color imagery and LIDAR data via a fixed-wing uncrewed aircraft system (UAS) for mapping Sawmill Springs area in the Kaibab National Forest in Arizona. Visual imagery was collected in joint photographic experts group (jpg) (for color imagery) format and Structure-from-Motion (SfM) photogrammetry techniques were applied to...

Multiple surface geophysical methods were used to characterize the hydrogeology and potential groundwater flow pathways for spring discharge near Quitobaquito Spring, located in Organ Pipe Cactus National Monument, AZ. The direct-current resistivity method was used with an electrical resistivity tomography (ERT) survey along six line-locations to determine groundwater elevation...

Observations of irrigated agricultural land within the Big Chino Groundwater Subbasin of the Verde River Groundwater Basin in Arizona. Crops were verified in situ once in 2024 on Aug 14th; based on digitized field boundaries. Field boundaries were digitized from U.S. Department of Agriculture, National Agriculture Imagery Program County Mosaic 2023 imagery for Arizona and supplemented...

Airborne electromagnetic (EM) and magnetic survey data were collected by GeoTerrex Ltd. in the Upper San Pedro Basin and Fort Huachuca, Arizona in 1997 and 1999. EM data were collected using a time-domain GEOTEM system towed behind a fixed-wing aircraft with 30Hz cycle rate, 696,000 Am2 dipole moment, and 4 ms pulse width. Magnetic data were collected using a CS-2 cesium vapor...

Observations of irrigated agricultural land within the Willcox Groundwater Basin in Arizona. Crops were verified in situ three times in 2024, first on May 29th, then on Sep 11th, and finally on Jan 15th; based on digitized field boundaries. Field boundaries were digitized from U.S. Department of Agriculture, National Agriculture Imagery Program County Mosaic 2023 imagery for Arizona and

Observations of irrigated agricultural land (excluding Wellton-Mohawk Irrigation and Drainage District) in the Lower Gila Groundwater Basin in Arizona. Lower Gila Groundwater Basin consists of three subbasins; Childs Valley in Pima County, Dendora Valley in Maricopa County, and Wellton-Mohawk in Yuma County. No irrigated agricultural land is found in the Childs Valley Subbasin or Pima...
