Book Description
This paper presents results from a Quaternary mapping project conducted in two areas of central mainland Nunavut that were located beneath the Keewatin Ice Divide during the last glaciation. Field work included surficial mapping, regional-scale till sampling, stratigraphic studies, and ice-flow indicator surveys. The paper summarizes the findings related to ice flow directions, patterns, and the sequence of flow events in the two map areas. Preliminary interpretations are offered of the ice flow record from the oldest recognized ice-flow events to the most recent flows.

Book Description
This study presents new measurements of glacial lake levels in the Wager Bay map sheet (National Topographic System 56 G), which includes the head of Wager Bay, Ford Lake, and Brown Lake. Two main types of glacial lakes are described in this paper. The first are proglacial lakes, where sediment-laden melt water that flowed down the natural slope of the land was obstructed by till or kame dams. The second are ice-marginal lakes, where water bodies were trapped between a major ice margin and the hillsides. The paper summarizes the main characteristics of each type.

Book Description
"You can't really know the place where you live until you know the shapes and origins of the land around you. To feel truly at home in the Bay Area, read Doris Sloan's intriguing stories of this region's spectacular, quirky landscapes."—Hal Gilliam, author of Weather of the San Francisco Bay Region "This is a fascinating look at some of the world's most complex and engaging geology. I highly recommend this book to anyone interested in an understanding of the beautiful landscape and dynamic geology of the Bay Area."—Mel Erskine, geological consultant "This accessible summary of San Francisco Bay Area geology is particularly timely. We are living in an age where we must deal with our impact on our environment and the impact of the environment on us. Earthquake hazards, and to a lesser extent landslide hazards, are well known, but the public also needs to be aware of other important engineering and environmental impacts and geologic resources. This book will allow Bay Area residents to make more intelligent decisions about the geological issues affecting their lives."—John Wakabayashi, geological consultant

Book Description
The mission of the U.S. Geological Survey (USGS) Water Resources Discipline is to provide the information and understanding needed for wise management of the Nation's water resources. Inherent in this mission is the responsibility of collecting data that accurately describe the physical, chemical, and biological attributes of water systems. These data are used for environmental and resource assessments by the USGS, other government agencies and scientific organizations, and the general public. Reliable and quality-assured data are essential to the credibility and impartiality of the water-resources appraisals carried out by the USGS.

Book Description
As the importance and dependence of specific mineral commodities increase, so does concern about their supply. The United States is currently 100 percent reliant on foreign sources for 20 mineral commodities and imports the majority of its supply of more than 50 mineral commodities. Mineral commodities that have important uses and face potential supply disruption are critical to American economic and national security. However, a mineral commodity's importance and the nature of its supply chain can change with time; a mineral commodity that may not have been considered critical 25 years ago may be critical today, and one considered critical today may not be so in the future. The U.S. Geological Survey has produced this volume to describe a select group of mineral commodities currently critical to our economy and security. For each mineral commodity covered, the authors provide a comprehensive look at (1) the commodity's use; (2) the geology and global distribution of the mineral deposit types that account for the present and possible future supply of the commodity; (3) the current status of production, reserves, and resources in the United States and globally; and (4) environmental considerations related to the commodity's production from different types of mineral deposits. The volume describes U.S. critical mineral resources in a global context, for no country can be self-sufficient for all its mineral commodity needs, and the United States will always rely on global mineral commodity supply chains. This volume provides the scientific understanding of critical mineral resources required for informed decisionmaking by those responsible for ensuring that the United States has a secure and sustainable supply of mineral commodities.
