Description of the Cloudy Pass batholith, the overlying Gamma Ridge volcanic rocks, and the still younger Glacier Peak volcano with discussion of the source magmas, their genetic ties, and the structures controlling their emplacement and eruption.
* Cascades climbing routes -- the guidebooks relied on for more than 25 years * Northwest climbing legend Fred Beckey has summited and explored hundreds of Cascade peaks * Hand-drawn maps and photos with route overlays, as well as approach information Volume II in the classic Cascade Alpine Guide series features expert information on more than 300 climbing and high routes in the Cascades. This volume covers the middle of the Cascade Range, from the foothills east of Puget Sound to Lake Chelan. You'll find geographical, historical, and geological overviews of the majestic mid-Cascade region, plus important tips on safety and backcountry usage. Legendary author/climber Fred Beckey includes technical and grade information for each route to make clear exactly what type of climb you are embarking upon.
This impressive scientific resource presents up-to-date information on ten thousand years of volcanic activity on Earth. In the decade and a half since the previous edition was published new studies have refined assessments of the ages of many volcanoes, and several thousand new eruptions have been documented. This edition updates the book’s key components: a directory of volcanoes active during the Holocene; a chronology of eruptions over the past ten thousand years; a gazetteer of volcano names, synonyms, and subsidiary features; an extensive list of references; and an introduction placing these data in context. This edition also includes new photographs, data on the most common rock types forming each volcano, information on population densities near volcanoes, and other features, making it the most comprehensive source available on Earth’s dynamic volcanism.
Presents information from the primary abiotic forces defining the system, and from the present hydrology, biogeochemistry and physics of major sites of organic carbon production of the McMurdo Dry Valleys. Additionally, research on the physical, chemical, and biological properties of the dry valley soils is included. The role of environmental management in long-term ecological studies is also addressed. The accompanying CDROM provides details and scale to visualize the McMurdo Dry Valleys from an ecosystem perspective.
