INTRODUCTION/PURPOSE Tsunamis are a series of ocean waves of extreme length and are almost always generated by undersea earthquakes, but also occasionally by volcanic eruptions, or massive undersea landslides. Their speed depends upon the depth of the water through which they are moving, and consequently the waves undergo accelerations or decelerations in passing respectively over an ocean bottom of increasing or decreasing depth. By this process the direction of the wave propagation may also change, and the wave energy can become focused or defocused.

    Issue 310 A Publication of the Docent Council, Martin Griffin Preserve of Audubon Canyon Ranch © March 2019 The Marincello That Might Have Been Lydia Mendoza and her fellow hikers headed to the Marin Headlands for the January hike. Along the way, they heard the tale of what was to have been a large, planned community that nearly became a reality in 1965. In the windswept and wild valley sweeping down to Rodeo Beach one can find the remnants of a development plan for 30,000 people; a city slated to be called Marincello. Here is the story, courtesy of and with thanks to Doug Ferguson. In 1965, Marin County approved a master plan for “Marincello,” a planned community of between 25,000 and 30,000 residents in the Marin Headlands west of Sausalito. Anticipating approval by a majority of the Board of Supervisors, the Marin IJ stated, in early November 1965: “It would be wishful thinking to dream forever of keeping these lands in their primeval state, especially under private ownership.”It took another five years and the determined opposition of dedicated citizens to prove that prophesy wrong. Dairying and the Forts Much of the Marin Headlands was still open after several generations of cattle grazing and dairying on the former Rancho Saucelito Mexican land grant. In 1850, the US government had purchased lands clustered around the Golden Gate for strategic defense of the Gateway. The Forts (Barry, Baker and Cronkhite) were installed and roads and artillery sites were built. Monterey pine and cypress trees(and later eucalyptus) were planted, and for many years the area was fenced off from the public.

    Field Trip 3 Geology of the Golden Gate Headlands Geology of the Golden Gate Headlands William P. Elder National Park Service, Golden Gate National Recreation Area, Calif. Introduction This field trip focuses on the rocks of the peninsular headlands found just north and south of the Golden Gate, on lands of the Golden Gate National Recreation Area. Exposed in dramatic seacliffs, these rocks not only form a spectacu- lar backdrop for the Golden Gate Bridge, but also provide a detailed geologic record of Pacific Basin and active conti- nental margin processes going back 200 million years. This is arguably one of the longest records of its type in the world. The significance of these rocks, however, goes beyond the geologic history that they tell, for they, and others of the Franciscan Complex associated with them, played a critical role in developing our current understanding of subduction zone mechanics and processes. Although the serpentine of the headlands, and its relationship to mountain building, was recognized as early as 1821 (see VanderHoof, 1951; Wahrhaftig, 1984a), it was not until the late 1970’s to early 1980’s that these rocks were understood in the light of modern tectonic concepts. This led to the publication of the volume edited by Blake (1984), which placed the Franciscan Complex into a modern plate tectonic framework. A detailed chronology of these geologic advances is provided by Wahrhaftig (1984a). The following article draws heavily upon the many excellent publications that the late Clyde Wahrhaftig wrote on the rocks of the San Francisco area, both for the professional geologist and the general public (for example, Wahrhaftig, 1984a, 1984b; Wahrhaftig and Murchey, 1987; Wahrhaftig and Sloan, 1989).
