With dogs and radar, volunteers search for remains at Mool-Mool, or Fort Simcoe State Park

Since time immemorial, Native Tribes in the Columbia Basin met at a village crossroads called Mool-Mool. In the wake of the Yakama Treaty of 1855, the site was of continual use as a U.S. military outpost, and for decades, the grounds included a boarding school operated by the Bureau of Indian Affairs, where children from the Yakama Nation were forced to attend. Today, volunteers and Yakama descendants are searching the 200-acre park for their relatives' remains.
