First Sight
Travelers usually see the basin long before they reach its rim. The golden desert suddenly breaks into bands of rust-red stone, clay, and blackened ridges. Beyond them, the land drops away into a broad depression several miles across. The walls are layered like exposed flesh: pale sandstone, iron-red sediment, and dark veins of stone running toward the basin floor.
After rare rains, thin streams spill down the slopes. The water gathers the red minerals of the cliffs until it looks disturbingly like blood flowing through hundreds of shallow cuts. The sight is responsible for the landmark's name—and for many of its oldest stories.
