Authorities said a city worker found the bones between the end of the Walnut Avenue access road and the nature center at 1:20 p.m. Tuesday. Burbank Police contacted the L.A. County Coroner's Office and closed the area off.
Investigators confirmed the bones are human, but the gender was not immediately determined.
Burbank police detectives and cadaver dogs searched the area between the entrance gate and the Stough Canyon Nature Center Tuesday.
Wednesday morning, detectives and coroner's investigators spent about two hours in Stough Canyon gathering the bones and other evidence, then opened the park to the public.
