This episode explores one of the most unique phenomena in geology; Hexagonal pillars of Basalt lava that were revealed during the last Ice Age. Located in the Eastern Sierra, this rare and beautiful feature ranks as one of the world's finest examples of columnar basalt. The region reveals a volatile geologic history, with reminders bubbling up from the valley floor. Baumann interviews Park Superintendent, Deanna Dulen, and USGS geologist, Mike Clynne. Baumann reaches his destination, and paints the Minarets of the Sierras overlooking the park itself.
Baumann sets his sites on one of the largest urban parks in the world: Golden Gate National Recreation Area. The park, which includes Alcatraz, the Marin Headlands, and the original military fortifications surrounding San Francisco, was conceived as part of a trend to make national park resources more accessible to urban populations. Interviews include Frank Heaney, Alcatraz prison guard, Heather Booth, park interpretive ranger, and Stephen Haller, civil war historian. Baumann completes his journey by painting the high dunes of Fort Funston and Ocean Beach.
