Bolinas resident and nudist Donald Holmes, 63, was found guilty Tuesday of willfully appearing naked in a state park, resisting a peace office and deterring an executive officer from performing a duty. A jury that began deliberating Friday found Holmes guilty of the misdemeanor offenses, which took place last August near the Steep Ravine hot springs south of Stinson Beach. Holmes was arrested and charged with resisting a peace officer after scuffling with ranger Roberto Walton of Mount Tamalpais State Park. Walton approached Holmes after seeing him in the park after sunset, a violation, and naked, another violation. According to prosecutors, Holmes refused warnings to cooperate and allegedly struck Walton in the face, causing a nosebleed and prompting the ranger to pepper spray the nudist. Holmes was found not guilty of violating a posted order to stay out of the park after sunset and battery against a peace officer. Holmes says the ranger was obstructing his access to medicine for his heart condition, and that the hot springs site is historically tolerant of nudists and after-dark visitors. He has been ordered to appear in court for sentencing May 17.
