MORGANTON, GEORGIA—On a chilly morning in early October, primatologist Steve Ross drives up to a chain-link gate blocking a narrow dirt road in northern Georgia. He steps out of his car into a swath of the Blue Ridge Mountains and watches the cresting Sun illuminate low fog on the wooded hills. “When I went to Tanzania,” he says, thinking back on the first time he saw wild chimpanzees, “it was just like this.”

A green sign on the gate reveals why Ross is here: “Project Chimps,” it reads. “Providing Lifelong Sanctuary to Chimpanzees Retired from Research.”
