Mount Tamalpais is a peak in Marin County, California, United States, often considered symbolic of Marin County. Danny MacRostie is a self-admitted obsessed with chasing the fog on Mount Tamalpais. He put together this 90-second time-lapse video over 18 months of filming.
When the conditions were right, I would be up and out the door by 4:00 in the morning to make the 45-minute drive and 30-minute hike up Mt. Tam to be setup for the sunrise. In the evenings I would race home from work, grab my gear, and head back out, often running down the trail with a backpack full of gear to be just in time for sunset.
