Alluvial Thickness Model, Yucaipa area, California

To help visualize the Yucaipa groundwater basin geometry, this animation of the elevation of the top of the basement rocks was created. The animation allows the viewer to “fly” over the Yucaipa groundwater basin, viewing the land surface, geology (grouped by major geologic perioid and colored by deposit type), faults (color coded based on location), wells in different subbasins in the Yucaipa study area, and the ridges and valleys of the shaded-relief elevation of the top of the basement complex. Animation published as part of USGS Open-File Report 2016-1127: Geologic structure of the Yucaipa area inferred from gravity data, San Bernardino and Riverside Counties, California (https://doi.org/10.3133/ofr20161127)
