WINSLOW, Ariz. (AP) — A dusty, barren field in the shadow of a busy Arizona interstate was for decades a place where children played freely, teenagers spooked themselves on Halloween and locals dumped trash, seemingly unaware of the history beneath them. Inside cotton sacks, burlap bags and blankets buried in the ground are the remains of stillborn babies, tuberculosis patients, and sick and malnourished Native Americans from Winslow and the nearby Navajo and Hopi reservations. It's hard, if not impossible, to know where each grave, some just 18 inches deep, is located at the Winslow Indian Cemetery.
