The historic American ship WAPAMA is the last surviving example of the wooden steam-powered schooners designed for the 19th- and 20th-century Pacific Coast lumber trade and coastal service. Since its launching in 1915, the WAPAMA has had a long and productive life in plying cargo and passengers along the stormy West Coast from Mexico to Alaska. As the sole survivor of the once numerous class, the WAPAMA was declared a National Historic Landmark in 1984. The wood structure of the WAPAMA has significantly deteriorated over the years and currently resides on a barge with internal and external structural supports. Portions of the vessel are unsafe for public access. Assisting in an effort to stabilize and rehabilitate this historic vessel, we conducted a field investigation on the current physical condition of the wooden structural members in January 2006. A variety of nondestructive testing (NDT) methods were employed to locate problem areas and define the severity of deterioration on key structural members such as keelsons, keel, ceiling planking, hull frames, clamps, and main deck beams. This report presents the main findings from this field investigation and demonstrates the use of state-of-the-art NDT technologies in evaluating physical and biological conditions of historic wood structures.

While the state of California remains one of the most striking and varied landscapes in the world, it has experienced monumental changes since European settlers first set foot there. The past two centuries have witnessed an ongoing struggle between environment and economy, nature and humanity that has left an indelible mark on the region. Green Versus Gold provides a compelling look at California's environmental history from its Native American past to conflicts and movements of recent decades. Acclaimed environmental historian Carolyn Merchant has brought together a vast storehouse of primary sources and interpretive essays to create a comprehensive picture of the history of ecological and human interactions in one of the nation's most diverse and resource-rich states. For each chapter, Merchant has selected original documents that give readers an eyewitness account of specific environments and periods, along with essays from leading historians, geographers, scientists, and other experts that provide context and analysis for the documents. In addition, she presents a list of further readings of both primary and secondary sources. Among other topics, chapters examine: California's natural environment and Native American lands the Spanish and Russian frontiers environmental impacts of the gold rush the transformation of forests and rangelands agriculture and irrigation cities and urban issues the rise of environmental science and contemporary environmental movement. Merchant's informed and well-chosen selections present a unique view of decades of environmental change and controversy. Historians, educators, environmentalists, writers, students, scientists, policy makers, and others will find the book an enlightening and important contribution to the debate over our nation's environmental history.
