The drilling project at Owens Lake commenced in April,1991. This Open-File Report represents an effort to makeavailable to other researchers our preliminary datacollected during the first year of study followingcompletion of the core-drilling phase. Nineteen datacollections and preliminary interpretations are presentedin the following sections. They are the work of fifteenfirst-authors and their numerous co-authors. Broadly,their topics include a field log of the core(1 contribution), sedimentological analyses (1), clay-mineral identification (1), geochemical analyses (5),dating and age estimates of the cored sediments (4), andidentifications of fossil materials (7).
The PRISM 8�x10� data set represents several years ofinvestigation by PRISM (Pliocene Research, Interpretation, andSynoptic Mapping) Project members. One of the goals of PRISMis to produce time-slice reconstructions of intervals ofwarmer than modern climate within the Pliocene Epoch. Thefirst of these was chosen to be at 3.0 Ma (time scale ofBerggren et al., 1985) and is published in Global andPlanetary Change (Dowsett et al., 1994). This documentcontains the actual data sets and a brief explanation of howthey were constructed. For paleoenvironmental interpretationsand discussion of each data set, see Dowsett et al., inpress. The data sets includes sea level, land icedistribution, vegetation or land cover, sea surfacetemperature...
The data contained in this report represent our preliminary findingsof the analyses of two cores of Pliocene and early Pleistocenesediments from the eastern Great Basin. This is a collaborativeproject involving specialists from the USGS, Kansas State University,and the University of California-Davis in paleontology (Thompson,Buchner, Forester, Bradbury), stratigraphy and sedimentology (Oviatt,Kelsey, Bracht), and paleomagnetism and environmental magnetism(Roberts).
