The Invisible Peak: Film screening and Q&A


“The Invisible Peak”

Film Screening and Q&A with filmmakers Gary Yost, George Daly, and Jamie Clay

7 pm, Thursday February 27
Free Admission

Mt. Tamalpais, sentinel peak of the SF Bay Area, is considered sacred by many, native and non-native alike. In 1950, the Army Corps of Engineers bulldozed the highest peak of the mountain to build an Air Force Station tasked with directing jet interceptors and short range Nike nuclear missiles against the potential threat of Russian nuclear bombers.  By 1980 the base was obsolete and summarily closed. The military literally walked away from dozens of structures on 106 acres, leaving behind a huge toxic mess on the mountain — cables, foundations, roads and infrastructure, all cut off from the public by miles of fencing.

Local filmmaker Gary Yost produced a new short documentary to shine a light on this hidden part of Mt. Tam.  Through the use of breathtaking timelapse cinematography, historical footage, interviews, CGI reconstruction of the mountaintop removal and construction of the military base, “The Invisible Peak” tells the virtually unknown story of the “missing” West Peak of Mt. Tamalpais and how local engaged citizens have been fighting to restore their mountain to a natural state for over 30 years.

Yost, along with co-director and music supervisor George Daly and visual effects wizard Jamie Clay, will show the 20-minute film and then demonstrate various techniques used to create it, including 3-axis automated camera motion control, 3D reconstruction of the original mountain and Air Force Station, plus how the emotionally-moving soundtrack was created.   “The Invisible Peak” represents a breakthrough in the way time-lapse and conventional cinematography have been seamlessly integrated to tell a complex story.
