Estimated thickness of the Quaternary sediment in the Wood River Valley aquifer system.

1	alluvium.thickness

An object of RasterLayer class. Each cell on the surface grid represents a depth measured from land surface in meters. Geographic coordinates are in units of meters, in conformance with the North American Datum of 1983 (NAD 83), and placed in the Idaho Transverse Mercator projection (IDTM). The spatial grid is composed of 565 rows and 429 columns, and has cell sizes that are constant at 100 meters by 100 meters.
