Documentary traces mountain lion's trek through Tiburon and beyond

Fairfax resident Amelie Bluestone had long been fascinated by mountain lions when she learned about P36, the juvenile male that visited the Tiburon Peninsula in 2023 during a 1,400-mile trek across the Bay Area.

“P36 is a great example of what mountain lions go through on a day-to-day basis, but he did travel a remarkable distance,” she says. “And that’s what made him stand out to me and what made his story so interesting.”

Bluestone directed “The Path of Puma-36,” a documentary short film that follows P36’s 17-month journey across Northern California while wearing a tracking collar as part of the Living with Lions project at Stinson Beach-based conservation nonprofit All Hands Ecology, founded as Audubon Canyon Ranch by late Belvedere conservationist Marty Griffin in 1962.

Bluestone’s film is streaming online through Oct. 30 as part of the 2025 Green Film Festival of San Francisco following a showing at San Francisco’s 4 Star Theater Oct. 25. She plans another screening in Fairfax in December, though details are still being worked out, and she also plans to make the documentary available online after she finishes the film-festival circuit.
