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.

Sometimes called "The Chivington Massacre" by those who would emphasize his responsibility for the attack and "The Battle of Sand Creek" by those who would imply that it was not a massacre, this event has become one of our nation’s most controversial Indian conflicts. The subject of army and Congressional investigations and inquiries, a matter of vigorous newspaper debates, the object of much oratory and writing biased in both directions, the Sand Creek Massacre very likely will never be completely and satisfactorily resolved. This account of the massacre investigates the historical events leading to the battle, tracing the growth of the Indian-white conflict in Colorado Territory. The author has shown the way in which the discontent stemming from the treaty of Fort Wise, the depredations committed by the Cheyennes and Arapahoes prior to the massacre, and the desire of some of the commanding officers for a bloody victory against the Indians laid the groundwork for the battle at Sand Creek.

Patriots, Traitors and Empires is an account of modern Korean history, written from the point of view of those who fought to free their country from the domination of foreign empires. It traces the history of Korea's struggle for freedom from opposition to Japanese colonialism starting in 1905 to North Korea's current efforts to deter the threat of invasion by the United States or anybody else by having nuclear weapons. Koreans have been fighting a civil war since 1932, when Kim Il Sung, founder of the Democratic People's Republic of Korea, along with other Korean patriots, launched a guerrilla war against Japanese colonial domination. Other Koreans, traitors to the cause of Korea's freedom, including a future South Korean president, joined the side of Japan's Empire, becoming officers in the Japanese army or enlisting in the hated colonial police force. From early in the 20th century when Japan incorporated Korea into its burgeoning empire, Koreans have struggled against foreign domination, first by Japan then by the United States. Patriots, Traitors and Empires, The Story of Korea's Struggle for Freedom is a much-needed antidote to the jingoist clamor spewing from all quarters whenever Korea is discussed.
