Stratigraphic Record of Pleistocene Initiation and Slip, Coyote Creek Fault
Geological Society of America Special Paper 365 2002 Stratigraphic record of Pleistocene initiation and slip on the Coyote Creek fault, Lower Coyote Creek, southern California Rebecca J. Dorsey* Department of Geological Sciences, 1272 University of Oregon, Eugene, Oregon 97403-1272, USA ABSTRACT The Coyote Creek fault is a major strand of the San Jacinto fault zone in southern California. Pleistocene sediments and sedimentary rocks exposed in the lower Coyote Creek area preserve a record of surface deformation, stream reorganization, and erosion that resulted from initiation and slip on the Coyote Badlands strand of the Coyote Creek fault. A well-exposed section of conglomerate and sandstone contains the 760 ka Bishop Ash and reveals (1) complete reversal of paleocurrents from north- west-directed (opposed to modern drainages) to southeast-directed (consistent with modern drainages); (2) fanning dips and a progressive unconformity bounded by the Coyote Creek and Box Canyon faults; (3) a thick gravel unit (Qg) that caps the fanning-dip section and accumulated between ca. 700 and 600 ka; and (4) post-Qg offset and deep erosion of the entire section. The fanning dips and reversal of paleo- currents are interpreted to record initiation of the Box Canyon and Coyote Creek faults by dip-slip (normal) displacement beginning at 750 ka. Strike-slip offset of Qg is equal to total offset on the Coyote Creek fault in the study area (ϳ6 km), indicating that strike-slip motion on the fault began after deposition of Qg, after ca. 600 ؓ 100 ka. This gives a time-averaged slip rate in Coyote Creek of ϳ10 mm/yr. -

Determination of Critical Habitat for the Endangered Nelson's Bighorn Sheep in Southern California
14-Turner.qxd 7/2/04 10:52 AM Page 427 NELSON'S BIGHORN SHEEP CRITICAL HABITAT 427 Determination of critical habitat for the endangered Nelson's bighorn sheep in southern California Jack C. Turner, Charles L. Douglas, Cecil R. Hallum, Paul R. Krausman, and Rob Roy Ramey Abstract The United States Fish and Wildlife Service’s (USFWS) designation of critical habitat for the endangered Nelson’s bighorn sheep (Ovis canadensis nelsoni) in the Peninsular Ranges of southern California has been controversial because of an absence of a quantitative, repeat- able scientific approach to the designation of critical habitat. We used 12,411 locations of Nelson’s bighorn sheep collected from 1984–1998 to evaluate habitat use within 398 km2 of the USFWS-designated critical habitat in the northern Santa Rosa Mountains, Riverside County, California. We developed a multiple logistic regression model to eval- uate and predict the probability of bighorn use versus non-use of native landscapes. Habitat predictor variables included elevation, slope, ruggedness, slope aspect, proximity to water, and distance from minimum expanses of escape habitat. We used Earth Resources Data Analysis System Geographic Information System (ERDAS-GIS) software to view, retrieve, and format predictor values for input to the Statistical Analysis Systems (SAS) software. To adequately account for habitat landscape diversity, we carried out an unsu- pervised classification at the outset of data inquiry using a maximum-likelihood clustering scheme implemented in ERDAS. We used the strata resulting from the unsupervised clas- sification in a stratified random sampling scheme to minimize data loads required for model development. -

Schneider, Ph.D., Associate State Archeologist, Colorado Desert District Matthew C. Hall, Ph.D. Director, Archaeological Research Unit University of California, Riverside Marla Mealey, M.A. Associate State Archeologist, Southern Service Center With a contribution by Heather Tompson September 2006 Schneider, Mealey, and Hall 2006 i MANAGEMENT SUMMARY During the mid-late 1990s, the University of California, Riverside - Archaeological Research Unit (UCR-ARU) contracted with California State Parks (CSP), through an Interagency Agreement, to carry out the first large-scale holistic systematic cultural resources inventory for Anza-Borrego Desert State Park (ABDSP). The project leader was Dr. Matthew C. Hall, Director of the UCR-ARU. Between 1995 and 1998, the UCR- ARU conducted fieldwork in ABDSP, following an elaborate Research Design that combined both a statistically based random-sample of parklands and a judgmental-area approach. The former was called Probabilistic Sample; the latter, Targeted Areas which were identified by ABDSP staff as areas with known high concentrations of cultural resources that had not been fully recorded. Field methods used in the two approaches were identical. The Research Design was developed to maximize the gathering of information about ABDSP cultural resources. As the project progressed, it became evident that, due to field conditions and findings, the Research Design was too ambitious and that the project could not be completed as was originally planned. -
