Aquifer System

Hydro-stratigraphic schematic profile of the aquifer system in Grand Canyon National Park. The profile shows the layers of rock strata, faults, and location of springs. The three confining layers are the (top to bottom: Toroweap Formation, Hermit Shale, and Bright Angle Shale). The perched Coconino (“C”) aquifer is in the Coconino Sandstone between the Toroweap and Hermit. Springs are adjacent to the confining layers. The Redwall-Muav (“R”) aquifer is between the Hermit and Bright Angel. Large springs are in the Muav above the Bright Angel.

Hydro-stratigraphic schematic profile of the aquifer system in Grand Canyon National Park. Faults (blue lines) serve as vertical conduits for groundwater. Large circles represent the dominant location of springs. Smaller circles represent additional locations of springs. The three confining layers represent relatively thick zones of impermeable rock.
