The complex human eye harvests light. It perceives seven to ten million colors through a synaptic flash: one-tenth of a second from retina to brain. Homo sapiens gangs up to 70 percent of its sense receptors solely for vision, to anticipate danger and recognize reward, but also—more so—for beauty.

For bighorns, topography is memory, enhanced by acute vision. They can anticipate the land's every contour--when to leap, where to climb, when to turn, which footholds will support their muscular bodies. To survive, this is what the band would have to do: make this perfect match of flesh to earth.
