For some students, it’s a popular place to run. Some simply ignore it. But the 16.5-acre Eugene Pioneer Cemetery, established in 1873, remains in large part a mystery to the students who walk through it.

They work dozens of hours each month beyond the sight of students, fueled by a sense of responsibility to preserve those buried there. For some of the volunteers, that includes their own ancestors.
