In February 2020, Pluto Press published Hidden San Francisco: The Guide to Lost Landscapes, Unsung Heroes, and Radical Histories by Chris Carlsson. This video, on the remarkable carving and flattening of hills throughout San Francisco's history, is the 8th of a baker's dozen of "stops" (there are 85 "stops" in four themed chapters, and an additional 44 "stops" in five walking tours in the appendix) turned into short videos. I hope it will whet your appetite for both buying the book (available at http://www.chriscarlsson.com/hidden-s...) but more importantly for going out into San Francisco and peeling back the layers of histories to find out how the hell it turned out like this!
