Beneath the Rim: Water Movement Pathways in the Grand Canyon
Beneath the Rim: Water Movement Pathways in the Grand CanyonPainting (gouache painting) is a generalized schematic view, not to scale, through the Grand Canyon with the Colorado River in the center, an unmined breccia pipe on the left side, and the Orphan Mine and associated breccia pipe on the right side. Dashed lines show a conceptual understanding of how water may interact with the Orphan Mine.
