|Covid-19|Sans Souci Valley Wikipedia
Sans Souci Valley was the name of a valley in San Francisco, California, in the area corresponding to present day's Lower Haight and Duboce Triangle. This valley once allowed excess storm water to flow from Buena Vista Hill and Lone Mountain (where the University of San Francisco is today), through the Panhandle, to the area located near Duboce Park, along the path today known to cyclists as The Wiggle. The creek was not a surface creek in the dune region except as overflow. Sans Souci Valley used to be the easiest route connecting Mission Dolores and the Presidio. According to historical sources cited in Hubert Howe Bancroft's History of California, the former "Lake Dolores" (or "Laguna de los Dolores") was located "in Sans Souci Valley, north of the Mission".
