Burro Creek Canyon is a deep, jagged gash carved into the Malpai Mesa of western Arizona. It's wild country?isolated, unforgiving, and ruled by rock, heat, and distance. Out here, cattle can turn feral in a heartbeat, slipping beyond fences and human control.

When an environmental group decides this hard land is the perfect place to reintroduce a jaguar, trouble follows fast.

Predators don't recognize property lines, and ranchers don't take kindly to experiments that put their livelihoods at risk. Tensions rise, cattle disappear, and the canyon becomes a battleground between modern ideals and old-time survival.

Read on to see how the cowboys of Burro Creek deal with a problem as ancient as the land itself.
