The Stanislaus Group in a Beheaded Drainage: Tectonics at the Margin of the Sierra Nevada Microplate
ABSTRACT THE STANISLAUS GROUP IN A BEHEADED DRAINAGE: TECTONICS AT THE MARGIN OF THE SIERRA NEVADA MICROPLATE West of Bridgeport Valley near the Sierra Nevada crest, the Little Walker Caldera erupted Late Miocene Stanislaus Group lavas (Table Mountain Formation) and ignimbrites (Eureka Valley Tuff). Remnants of these rocks are now distributed from the western Sierra Nevada foothills across the range and into the Walker Lane. This wide distribution is attributed to the lavas flowing down paleochannels, and provides an excellent marker for post-emplacement deformation in the region. Priest (1978) documented a thick section of these lavas along Flatiron Ridge and other peaks surrounding Buckeye Canyon, including four members in stratigraphic order: Lower, Large Plagioclase, Two-Pyroxene, and Upper Member. 40Ar/39Ar geochronology indicates these Table Mountain Formation Lavas erupted from 10.4-9.5 Ma. Lithologically similar lavas have been identified near Rancheria Mountain, geochemical and paleomagnetic data support this correlation. The lavas flowed down a now-beheaded late Miocene drainage, supporting a westward shift of the Sierra Nevada crest since the Late Miocene. Paleomagnetic data from Priest’s Measured Section reveal that the Upper Member and the Two-Pyroxene Member are reversed polarity. The Large Plagioclase Member and the Lower Member flows are normal polarity. Based on remanence, lithology, and geochemistry, we correlate the Upper Member with the Rancheria Mountain lavas, requiring the presence of a 30 km long paleochannel for the lava to flow down. The Sierra Nevada crest currently divides these ii outcrops of Stanislaus Group lavas. Since lava flows downhill from its source, and Priest’s Measured Section is the most proximal locality, the crest of the Sierra Nevada must have been near to or east of Priest’s Measured Section in the late Miocene.

Sierra Nevada Bighorn Sheep a Message from the President
A JOURNAL FOR MEMBERS OF THE YOSEMITE ASSOCIATION Winter 2005 Volume 67 Number 1 Sierra Nevada Bighorn Sheep A Message from the President arm (at least as warm as we can get them) greetings from snowy Yosemite. We’re experiencing one of the wintriest winters we’ve had in years. If you want to see just how much snow there is, check out our new webcam view (www.yosemite.org/vryos) which has just about been eliminated by the accumula- tion of the white stuff. Unfortunately, the camera is pretty much inaccessible this time of year, so we’ll have to rely on the sun to clear the view! It’s been figuratively wintry in the park, too. As if the loss of artist Jane Gyer earlier in 2004 wasn’t Wenough, Yosemite historian, author, and long-time friend of the association Shirley Sargent passed away in December at the age of 77. We’ve included an article about Shirley and her remarkable life in this journal. On a more positive note, we’re excited to report progress on at least two project fronts. The Yosemite Valley Visitor Center lobby and store remodel is well underway, with representatives of Souza Construction of Visalia responsible for the makeover. The plan is to have the facility completed and open to the public in mid-March! We hope you’ll be impressed. In other exciting news, we learned in December that the James and Rebecca Morgan Family Foundation had awarded the Yosemite Association a challenge grant in the sum of $35,000 for our cooperative student intern program.

HICKEL, Secretary GEOLOGICAL SURVEY William T. Pecora, Director For sale by the Superintendent of Documents, U.S. Government Printing Office Washington, D.C. 20402 In accordance with the provisions of the Wilderness Act (Public Law 88-577, Sept. 3,1964) and the Conference Report on Senate bill 4, 88th Congress, the U.S. Geological Survey and the U.S. Bureau of Mines are making mineral surveys of wilderness and primitive areas. Areas officially designated as "wilderness," "wild," or "canoe," when the act was passed were incorporated into the National Wilderness Preservation System. Areas classed as "primi tive" were not included in the Wilderness System, but the act provides that each primitive area should be studied for its suitability for incorporation into the Wilderness System. The mineral surveys constitute one aspect of the suitability studies. This bulletin reports the results of a mineral survey in the Emigrant Basin primitive area, California. The area discussed in the report corresponds to the area under consideration for wilderness status. It is not identical with the original Emigrant Basin Primi tive Area as defined because modifications of the bound ary have been proposed for the area to be considered for wilderness status.

DeOreo Department of Earth Science, University of California, Santa Barbara, California 93106, USA Ian Skilling Department of Geology and Planetary Sciences, University of Pittsburgh, 200 SRCC, Pittsburgh, Pennsylvania 15260, USA ABSTRACT We integrate new stratigraphic, structural, geochemical, geochronological, and magnetostratigraphic data on Cenozoic volcanic rocks in the central Sierra Nevada to arrive at closely inter-related new models for: (1) the paleogeography of the ancestral Cascades arc, (2) the stratigraphic record of uplift events in the Sierra Nevada, (3) the tectonic controls on volcanic styles and compositions in the arc, and (4) the birth of a new plate margin. Previous workers have assumed that the ancestral Cascades arc consisted of stratovolcanoes, similar to the modern Cascades arc, but we suggest that the arc was composed largely of numerous, very small centers, where magmas frequently leaked up strands of the Sierran frontal fault zone. These small centers erupted to produce andesite lava domes that collapsed to produce block-and-ash fl ows, which were reworked into paleocanyons as volcanic debris fl ows and streamfl ow deposits.
