There is no evidence any remains were left behind, but the Confederated Tribes of the Grand Ronde is asking the state to make sure before apartments and single-family homes are built on Oregon State Hospital's North Campus. Opened 136 years ago as the Oregon State Insane Asylum, the hospital had a cemetery for 30 years. It closed in the early 1910s and state lawmakers ordered the remains exhumed in 1913, when the facility was renamed the Oregon State Hospital. It's unclear if any of the people believed to have been buried in the hospital's cemetery are in the discovered urns. The state maintains an online list of the 2,972 cremated remains that have not been claimed for families to search.
