Passage: Youth activism as a social phenomenon in the United States truly became defined in the mid- to late-nineteenth century when young people began forming labor strikes in response to their working conditions, wages, and hours. Mary Harris "Mother" Jones organized the first youth activism in the U.S., marching 100,000 child miners from the coal mines of Pennsylvania to the U.S. Capitol in Washington, D.C. in 1908. Youth newspaper carriers soon followed. These actions isolated youths' interests in the popular media of the times, and separated young people from their contemporary adult labor counterparts. This separation continued through the 1930s, when the American Youth Congress presented a "Bill of Youth Rights" to the US Congress. Their actions were indicative of a growing student movement present throughout the US from the 1920s through the early 1940s. The 1950s saw the Student Nonviolent Coordinating Committee bring young people into larger movements for civil rights. All the way back in 1959, Rev. Dr. Martin Luther King, Jr. engaged youth activists in protesting against Bull Connor's racist law enforcement practices in Birmingham, Alabama. The youth activism of Tom Hayden, Keith Hefner and other 1960s youth laid a powerful precedent for modern youth activism. John Holt, Myles Horton and Paulo Freire were important in this period. Youthful life and expression defined this era.

Passage: The First Indochina War had raged, as guerrilla warfare, since 19 December 1946. From 1949, it evolved into conventional warfare, due largely to aid from the communists of the People's Republic of China ("PRC") to the north. Subsequently, the French strategy of occupying small, poorly defended outposts throughout Indochina, particularly along the Vietnamese-Chinese border, started failing. Thanks to the terrain, popular support for August Revolution and support for decolonization from bordering China and the U.S.S.R., the Viet Minh had succeeded in turning a "clandestine guerrilla movement into a powerful conventional army", following asymmetric warfare theory laid by Mao Tse Tung, something which previously had never been encountered by the western colonial powers. In October 1952, fighting around the Red River Delta spread into the Thai Highlands, resulting in the Battle of Nà Sản, at which the Viet Minh were defeated. The French used the lessons learned at Nà Sản – strong ground bases, versatile air support, and a model based on the British Burma Campaign – as the basis for their new strategy. The Viet Minh, however, remained unbeatable in the highland regions of Vietnam, and the French "could not offset the fundamental disadvantages of a roadbound army facing a hill and forest army in a country which had few roads but a great many hills and forests".

Passage: The northern segment of the fault runs from Hollister, through the Santa Cruz Mountains, epicenter of the 1989 Loma Prieta earthquake, then up the San Francisco Peninsula, where it was first identified by Professor Lawson in 1895, then offshore at Daly City near Mussel Rock. This is the approximate location of the epicenter of the 1906 San Francisco earthquake. The fault returns onshore at Bolinas Lagoon just north of Stinson Beach in Marin County. It returns underwater through the linear trough of Tomales Bay which separates the Point Reyes Peninsula from the mainland, runs just east of Bodega Head through Bodega Bay and back underwater, returning onshore at Fort Ross. (In this region around the San Francisco Bay Area several significant "sister faults" run more-or-less parallel, and each of these can create significantly destructive earthquakes.) From Fort Ross, the northern segment continues overland, forming in part a linear valley through which the Gualala River flows. It goes back offshore at Point Arena. After that, it runs underwater along the coast until it nears Cape Mendocino, where it begins to bend to the west, terminating at the Mendocino Triple Junction.
