17-19 December 2001: Death Valley, California

More than 200 field-trip participants and leaders feasted on the Quaternary and Pliocene geology of the Death Valley Region, with a focus on recent observations on tectonics, stratigraphy, and lake cycles. The leaders (Michael Machette, Ralph Klinger, Jeff Knott, and Andrei Sarna-Wojcicki) were appropriately roasted and given special awards at a campground bonfire. The 254-page guidebook may be downloaded. Two-hundred copies of a second edition (minor corrections, new cover) are available from: Death Valley Natural History Association, P.O. Box 188, Death Valley, CA 92328-0188. Phone: 760 786-3285, Email:

12-14 October 2001: Northern Walker Lane and northeast Sierra Nevada

With contributions from Ken Adams, Rich Briggs, Bill Bull, Jim Brune, Darryl Granger, Alan Ramelli, Clifford Riebe, Tom Sawyer, John Wakabayashi, and Chris Wills, this field trip explored the neotectonics, paleoseismology, and evolution of the northern Walker Lane, as well as general controls on erosion rates, and topographic evolution of the Sierra Nevada. The guidebook, and notices for upcoming events, may be viewed and downloaded from the Pacific Cell website.

Don't miss the 2002 Pacific Cell trip to the Central Nevada Seismic Belt, led by John Caskey.

17-19 February 2001: Death Valley, California

The Pacific Cell FOP trip for 2000 (postponed) will be in Death Valley. Primary leaders include Ralph Klinger (University of Colorado-Boulder), Jeff Knott (University of California), Michael Machette (USGS-Denver) and Andrei Sarna-Wojcicki (USGS-Menlo Park). The preliminary itinerary includes a day looking at tectonics and Plio Pleistocene stratigraphy along the Furnace Creek fault zone in Northern Death Valley (Klinger), a day on the late Cenozoic deposits of the Furnace Creek area (Machette), and a day on late Pliocene and Pleistocene stratigraphy, slip rate of the Death Valley fault zone, and evidence for pluvial lakes (Knott).

The trip will probably be limited to 150 participants owing to our field trip permit with the National Park Service. However, we will have use of the Texas Springs Campground (group sites and individual). Anticipated price is $30-40. We will use the last Pacific Cell FOP e mail list for our first notification this fall. If you want to be added to the list, contact Michael Machette U.S. Geological Survey, MS 966, PO Box 25046, Denver, CO 80225; 303-273 8612; Fax: -8600.
