Book Description
In Embracing Watershed Politics, political scientists Edella Schlager and William Blomquist provide timely illustrations and thought-provoking explanations of why political considerations are essential, unavoidable, and in some ways even desirable elements of decision making about water and watersheds. With decades of combined study of water management in the United States, they focus on the many contending interests and communities found in America's watersheds, the fundamental dimensions of decision making, and the impacts of science, complexity, and uncertainty on watershed management.

Book Description
Through theoretical discussion as well as hands-on participatory learning approaches, Thomashow provides concerned citizens, teachers, and students with the tools needed to become reflective environmentalists. Mitchell Thomashow, a preeminent educator, shows how environmental studies can be taught from different perspective, one that is deeply informed by personal reflection. Through theoretical discussion as well as hands-on participatory learning approaches, Thomashow provides concerned citizens, teachers, and students with the tools needed to become reflective environmentalists. What do I know about the place where I live? Where do things come from? How do I connect to the earth? What is my purpose as a human being? These are the questions that Thomashow identifies as being at the heart of environmental education. Developing a profound sense of oneself in relationship to natural and social ecosystems is necessary grounding for the difficult work of environmental advocacy. In this book he provides a clear and accessible guide to the learning experiences that accompany the construction of an "ecological identity": using the direct experience of nature as a framework for personal decisions, professional choices, political action, and spiritual inquiry. Ecological Identity covers the different types of environmental thought and activism (using John Muir, Henry David Thoreau, and Rachel Carson as environmental archetypes, but branching out into ecofeminism and bioregionalism), issues of personal property and consumption, political identity and citizenship, and integrating ecological identity work into environmental studies programs. Each chapter has accompanying learning activities such as the Sense of Place Map, a Community Network Map, and the Political Genogram, most of which can be carried out on an individual basis. Although people from diverse backgrounds become environmental activists and enroll in environmental studies programs, they are rarely encouraged to examine their own history, motivations, and aspirations. Thomashow's approach is to reveal the depth of personal experience that underlies contemporary environmentalism and to explore, interpret, and nurture the learning spaces made possible when people are moved to contemplate their experience of nature.

Book Description
This bulletin serves not only to introduce the non-geologist to the rich geology of Millard County, but also to provide professional geologists with technical information on the stratigraphy, paleontology, and structural geology of the county. Millard County is unique among Utah’s counties in that it contains an exceptionally complete billion-year geologic record. This happened because until about 200 million years ago the area of present-day Millard County lay near sea level and was awash in shallow marine waters on a continental shelf upon which a stack of fossil-bearing strata more than 6 miles (10 km) thick slowly accumulated. This bulletin summarizes what is known about these strata, as well as younger rocks and surficial deposits in the county, and provides references to scientific papers that describe them in greater detail. Mountains North 30 x 60 (1:100,000-scale) quadrangles. These companion maps and this bulletin portray the geology of Millard County more completely and accurately than any previously published work.

Book Description
The Peninsula Watershed has been integral to the story of San Francisco's growth ever since the Gold Rush. The rapid influx of settlers to San Francisco during the Gold Rush spurred a sudden demand for a reliable water source, which led to the formation of the Spring Valley Water Works (later purchased by the Spring Valley Water Company [SVWC]) in 1858 (Hanson 2005 ). Over the subsequent 70 years, SVWC bought up large swaths of land on the Peninsula, and constructed a complex system of dams, tunnels, and pipes to capture and transport water to San Francisco. Within the Peninsula Watershed, this system includes the Crystal Springs and San Andreas reservoirs, located in the San Andreas Creek, Laguna Creek, and Upper San Mateo Creek basins along the San Andreas Fau The City of San Francisco purchased SVWC in 1930, and today the Peninsula Watershed, managed by the San Francisco Public Utilities Commission (SFPUC), continues to be a key source of water for San Francisco and for other communities in the South and East Bay. Despite the past 150 years of reservoir construction and other hydrologic modifications, the construction of transportation and utility corridors, and the large-scale suburban development that has occurred to the east, the Peninsula Watershed has remained largely undeveloped and is managed to protect water quality, water supply, wildlife habitat, and a range of other natural and cultural resources. The watershed supports some of the largest intact remnants of contiguous habitat in the region, including extensive oak woodlands, old-growth Douglas-fir forests, serpentine grasslands, chaparral, and coastal scrub. Over the past 250 years since Spanish explorers first set foot on the watershed, however, changes in disturbance regimes and other large-scale anthropogenic modifications, including fire suppression, homesteading, livestock grazing, agriculture, tree planting, introduction of plant pathogens, spread of invasive species, and climate change, have altered vegetation dynamics and changed the distribution and structure of vegetation communities throughout the watershed. The changes have raised many questions about the historical ecology of the watershed: What was the extent, distribution, and composition of terrestrial, riparian, and wetland habitats prior to Euro-American modification? How have vegetation distributions changed over the past two centuries, and what are the implications of those changes for species support? Are there remnant patches of relatively unmodified habitat present in the watershed, or areas that are currently in a state of recovery? Where are current habitat characteristics most similar to or different from historically documented conditions? How have key natural and anthropogenic disturbance regimes and processes changed over time? The Peninsula Watershed Historical Ecology Study aims to advance understanding of landscape conditions of the Peninsula Watershed prior to major Euro-American modification, and to provide insights into the nature and drivers of vegetation change since the first Spanish explorers set foot in the watershed 250 years ago. The primary goal of the research was to examine the historical extent, distribution, and composition of terrestrial vegetation types and their trajectories of change within the watershed. To the extent possible, research also addressed historical riparian, wetland, and estuarine habitats; hydrology and sediment dynamics; wildlife support; land use history; and a range of other topics.
