Description:
Abstract:
The drilling project at Owens Lake commenced in April, 1991. This Open-File Report represents an effort to make available to other researchers our preliminary data collected during the first year of study following completion of the core-drilling phase. Nineteen data collections and preliminary interpretations are presented in the following sections. They are the work of fifteen first-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), and identifications of fossil materials (7).
Purpose:
An important element of the investigations supported by the USGS through its Global Change and Climate History Program is the record of past changes in precipitation in now-arid parts of the United States. More than a century of geologic investigations has shown that major changes in precipitation and runoff occurred throughout much of this region, as shown by the evidence of fluctuations in the levels of lakes in the Great Basin. Although these basins--sometimes termed "nature's rain guages"--clearly document major changes in climate during the past few hundred thousand years, there is an inadequate consensus about those lakes' ages or the quantitative meaning and meteorological significance of their fluctuations. The timing and intensities of these climatic changes pose important questions to earth and paleoclimatic scientists.

Attribute_Accuracy:
Attribute_Accuracy_Report:
Accuracy of the attributes is described in great detail in the text accompanying the data tables.
Logical_Consistency_Report:
Each core segment was logged in the field in terms of its "drive" number (which represented the times the empty core barrel had re-entered the core hole) and "slug" designation (the letter representing each 1.5m-long core segment from that drive, with "A" at the top); starting and ending depths of each drive (in feet and inches) were based on the driller's log; they were later converted to meters to the nearest 0.01m. Unrecovered core, logged as "No core", was arbitrarily placed at the base of each drive.
Completeness_Report:
Core recovery for Core OL-92 was better than 80 percent. Because of drilling technicalities, Core OL-92 is actually three cores from essentially-adjacent sites; Cores OL-92-1 and -2 were recovered from the surface of a man-made drill- pad (which was used as the "core-depth datum" throughout the project, even though actually 0.94 m above the dry-lake bed), and Core OL-92-3 was recovered a few meters east of the drill pad. The depths of their cored intervals overlap slightly. Core OL-92-1 extends from 5.49 m to 61.37 m below the pad surface (85 percent core recovery), and OL-92-2 extends from 61.26 m to 322.86 m below that surface (79 percent recovery). Core OL-92-3 extends from 0.94 m (depth of the lake surface below the drill pad) to 7.16 m (100 percent recovery).

Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The drill site is reported as approximately 140m west and 420m north of the southeast corner of Section 9, T18S, R37E [MDBM]. This suggests that the horizontal position is known to within five meters.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Between 5.49 m and 61.37 m (total = 55.88 m), "no core" entries in log account for 8.50 m; thus, 85 percent of this interval was recovered as core (although some of it was suspected of being "cuttings, not core").
Between 61.26 m and 322.86 m (total cored thickness = 261.60 m), "no core" entries in log account for 54.71m; thus, 79 percent of this interval was recovered as core (although some of it was suspected of being "cuttings, not core").
From 0.94 m to 3.52 m, core was recovered as cuttings or short segments that were logged but not saved; from 3.52 m to 7.16 m, core recovery was 100 percent, all of which was logged and archived.

Process_Step:
Process_Description:
The 323m core designated OL-92 was recovered between April 22 and June 9, 1992, from the south-central part of (now-dry) Owens Lake, Inyo County, California. The drill site is approximately 140m west and 420m north of the southeast corner of Section 9, T18S, R37E [MDBM]. Permission to drill the core hole was obtained by the U.S. Geological Survey from the California State Lands Commission which has jurisdiction of State lands that include the surface of Owens Lake. The drill site and a large amount of land around it is leased by the State of California to the Lake Minerals Corporation; they permitted our group to use their roads and were helpful in numerous other ways.
