Question: 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.
Link Information: The Gualala River is a river on the northern coast of California. Most of the river is in Sonoma County, but a portion is in Mendocino County. The headwaters of the 40 mi river ( Answer: 40

Answer: How long is the Gualala River?

Question: Passage: In a publication of 1941, Norman Tindale, together with the American anthropologist Joseph Birdsell, published a paper suggesting that there were 12 Negrito tribes living on the coastal and rainforest areas around Cairns. The idea had been developed by Birdsell during field work in 1937-8. They were characterized by very short stature, curly hair, and yellowy-brown skin. Six of them were Dyirbal speakers, such as the Jirrbal, Girramay, Gulngai and Djiru within the Murray Upper/Tully Area. Of the others, located further north beyond Cairns, two spoke varieties of Djabugay, and three spoke dialects of Yidin. The remaining tribe were the Mbabaram, whom Tindale took to be strong evidence for his hypothesis because their language, in so far as it had been reported, diverged substantially from the surrounding tongues, and appeared to be wholly atypical, compared to the standard Australian aboriginal languages.

Question: Passage: Wasson was born Isabel Deming Bassett in Brooklyn, NY on January 11, 1897, daughter of urban planner Edward Bassett and Annie Preston Bassett, and sister of inventor and engineer Preston Bassett. Wasson graduated Phi Beta Kappa from Wellesley College in 1918, majoring in history so she could take a wide range of science courses. She took classes in geology after graduation at the University of Chicago and the Massachusetts Institute of Technology. She met her future husband, petroleum geologist Theron Wasson, whom she married in 1920, while working towards a master's degree in geology at Columbia University, which she finished in 1934. They had three children: Elizabeth W. Bergstrom, a biologist; Edward B. Wasson, a petroleum geologist; and Anne Harney Gallagher, an art historian. Wasson worked as a petroleum geologist in her husband's office at the Pure Oil Company from the early 1920s until 1928. She published two scholarly articles on geology, one co-authored with her husband about an oil field discovered by Pure Oil in 1914, and another by herself about the ages of rock formations in Ohio and new terminology for them; the latter was cited in a number of other papers and a recent book. After 1928 she spent over 50 years in River Forest, IL, teaching science in the local public schools, lecturing, bird watching (ornithology), and mentoring generations of young naturalists. She was quoted in this 1986 Chicago Tribune article as an expert on local geology at age 89. She was honored for her contributions to local history in 1982 when the Wasson Room was named after her in a local school to hold local history resources. Her interests included archaeology; she discovered a Native American religious mound in Thatcher Woods, near her house in River Forest, in the 1930s. An article about her discovery called her "the one who started the environmental education movement in America back in the 1920s and '30s." Theron and Isabel divorced in 1953 and she did not remarry. From 1953-1954, Wasson served as President of the Chicago Ornithological Society. Wasson also taught classes at the Morton Arboretum in Lisle, Illinois. She died in La Grange Park, IL, in 1994.
