Carl M Wentworth
Carl, a Scientist Emeritus with the Geology, Minerals, Energy, and Geophysics Science Center, is continuing a varied career that has included geologic mapping, geologic safety of nuclear power reactors, tectonic studies combining geology and geophysics, landslide hazards, and Quaternary stratigraphy and tectonics. He holds Ph.D. and M.S. degrees in Earth Science from Stanford University.
Carl obtained a Ph.D. degree from Stanford University in 1967, having joined the U.S. Geological Survey full time in Menlo Park, CA, in 1963. He retired in 2004 and has continued in emeritus status in the Menlo Park, CA, office since. His work over the past 55 years, mostly in California, has involved geologic mapping; study of landslide, fault and earthquake hazards; management of a national research program on hazards to power reactors; investigation of crustal structure using deep reflection profiling; study of a deep Quaternary basin and its cyclic record of climate variation; and study of the Franciscan Complex and its tectonostratigraphic terranes.

Santa Clara Valley water district multi-aquifer monitoring-well site, Coyote Creek Outdoor Classroom, San Jose, California
The U.S. Geological Survey (USGS), in cooperation with the Santa Clara Valley Water District (SCVWD), has completed the first of several multiple-aquifer monitoring-well sites in the Santa Clara Valley. This site monitors ground-water levels and chemistry in the one of the major historic subsidence regions south of San Jose, California, at the Coyote Creek Outdoor Classroom (CCOC) (fig. 1) and proAuthorsR.

Bennett1:100,000-scale topographic contours derived from digital elevation models, San Francisco Bay region, California: a digital database
This report presents a consistent set of 1:100,000-scale vector topographic contours for all eleven 30x60-minute quadrangles in the San Francisco Bay region for use in visualizing the topography and preparing maps of the region. The contours were prepared by contouring an areally continuous 30-m altitude grid (National Elevation Dataset, Jan., 1999), and differ from USGS hypsographic DLG's (availaAuthorsHeather M.

This Open-File Report is a digital geologic map database. The report serves to introduce and describe the digital data. There is no paper map included in the Open-File Report. The report includes PostScript and PDF plot files that can be used to plot images of the geologic map sheet and explanation sheet.

Truncation of metamorphic isograds and fold axes within coherent terranes of Franciscan metagraywacke by intervening zones of melange indicate that the melange is tectonic and formed after the subduction-related metamorphism and folding. These relations are expressed in two terranes of blueschist-facies rocks of the Franciscan Complex in the Mt. Hamilton area, northern California-the Jurassic YollAuthorsM. C. Blake, C. M.

The confidence parameters in Table 5 and Figures 7 -12 in Bakun and Wentworth (1997) were calculated using the site corrections for MI(4) rather than Bakun and Wentworth's (1997) preferred relation MI(3). The conclusions of Bakun and Wentworth (1997) are not changed by these corrections. The corrected Table 5 and Figures are in this report and at http://quake.wr.usgs.gov/~bakun/.AuthorsW. H. Bakun, C.
