The coroner's office dated the bones as older than a century and will reinter them at Mount Olivet Cemetery.
Their identities, however, are lost to history.
"Cheesman's cemetery had a lot of criminals and paupers buried without headstones or any records," said Jill McGranahan, spokeswoman for the Denver Parks and Recreation Department. "There's really nowhere to look to find out who these bones belonged to."
Today a scenic park southeast of downtown, Cheesman was part of the 320 acres set aside as Prospect Hill Cemetery in 1859.
