View Original Image at Full SizeThe characteristic red color of the Waimea Canyon on the island of Kauai, Hawaii, results from chemical weathering. The original lava flows were chemically weathered by rainwater and the Waimea River, dissolving out the soluble elements, and concentrating relatively insoluble, rust-red iron oxide (hematite) on the surface. The red mud of the Waimea Canyon is used today as a resource by a local company to color their t-shirts.
