  Description:
    Abstract:
      This database, which was compiled from new mapping and published and unpublished data, contains the geologic data used to produce the  Cuddeback Lake 1:100,000-scale quadrangle located in the western Mojave Desert north-northeast of Los Angeles, between the southern Sierra Nevada and San Bernardino Mountains, in Kern and San Bernardino Counties, California.  

      The geologic features that were mapped as part of this project include geologic contacts, bedrock and surficial geologic units, faults, and folds.  Geologic features were identified and annotated on black and white, 1:40,000-scale aerial photographs that were taken in 1965, 1972, 1977, and 1994.   South of the Rand Mountains and northwest of the Black Mountains, 1:24,000-scale color aerial photography was used for mapping.  The annotated aerial photographs were field checked during the mapping process.  The identified contacts and unit calls were transferred from the annotated aerial photographs by digitizing on orthophotographs in ArcMap.

      Note:  This metadata report provides an overview of the data content of this geodatabase.  In addition, each feature class (except annotation feature classes) has a corresponding metadata report that should be referred to for additional Spatial Data Organization, Data Quality, and Entity Attribute information.
    Purpose: One of a series of 1:100,000-scale surficial maps and geologic databases of the Mojave Desert region produced to aid in understanding the potential long-term effects of urban development and land use.  The multi-purpose surficial geologic maps and databases produced by this project contain information that is being used for land-management decisions with regard to (1) ground-water availability, (2) natural hazard risks, such as earthquakes, landslides, and debris flows, (3) ecosystem sustainability, (4) effects of climate change, and (5) soil compaction.

  Use_Constraints:
    Uses of this digital geologic map should not violate the spatial resolution of the data. Although the digital form of the data removes the constraint imposed by the scale of a paper map, the detail and accuracy inherent in map scale are also present in the digital data. The fact that this database was edited for a scale of 1:100,000 means that higher resolution information is not present in the dataset. Plotting at scales larger than 1:100,000 will not yield greater real detail, although it may reveal fine-scale irregularities below the intended resolution of the database. Similarly, where this database is used in combination with other data of higher resolution, the resolution of the combined output will be limited by the lower resolution of these data.

    Any hard copies utilizing these datasets shall clearly indicate their source. If users modify the data in any way they are obligated to describe the types of modifications they have performed. User specifically agrees not to misrepresent these datasets, nor to imply that changes they made were approved by the U.S. Geological Survey.

Data_Quality_Information:
  Attribute_Accuracy:
    Attribute_Accuracy_Report: Geologic features were identified, mapped, digitized, and attributed by the principle investigators (Lee Amoroso and David M. Miller).  The features were symbolized based on their attributes and plotted at 1:24,000-scale in some locations and 1:100,000-scale in the remaining parts of the map, then compared visually with the original annotated aerial photographs.  The map was then compiled at 1:100,000 scale.
  Logical_Consistency_Report: This database has been reviewed and meets USGS standards.  All features have attributes.  Each line segment has a length and directionality that is appropriate for the geologic feature it depicts.  No sliver polygons are present.
  Completeness_Report: This report is designed to describe completely the surficial geology at a 1:100,000 scale. This database is considered complete.  All geologic features depicted on the source maps were digitized and attributed.
  Positional_Accuracy:
    Horizontal_Positional_Accuracy:
      Horizontal_Positional_Accuracy_Report: Most of the geologic features in this database are considered to be accurately located to within +/- 5 meters of their actual location on the topographic base map.  This accuracy diminishes in areas where the topography is either flat or very steep or where the geologic feature of interest is difficult to discern.   (Note:  Refer to the metadata report for a specific feature class of interest for more detailed information about the positional accuracy of the features).
  Lineage:
    Process_Step:
      Process_Description: Geologic features were identified and annotated on black and white, 1:40,000-scale aerial photographs that were taken in 1965, 1972, 1977, and 1994.   South of the Rand Mountains and northwest of the Black Mountains, 1:24,000-scale color aerial photography were used for mapping.  The identified contacts and units were transferred from the annotated aerial photographs by digitizing in ArcMap.  The linework was plotted at 1:24,000 or 1:100,000, depending on the location and compared to the aerial photographs.  Errors in line attribution, directionality, and location were edited as needed to achieve an error-free database.

  Overview_Description:
    Entity_and_Attribute_Overview:
      Surficial geologic units are commonly thin (<2 m) veneers over older units including bedrock.  Where this is common, the unit descriptors are shown on the map separated by a slash (/).  The younger, overlying unit is listed first.  For example, Qya/Qoa indicates a veneer of younger alluvial deposits overlying old alluvial deposits and Qye/fpg indicates a young eolian deposit over grus-producing felsic plutonic rock.   This usage also applies to hillslope deposits, for example Qha/mv indicates abundant hillslope deposits over mafic volcanic rock.  

      	The areal extent of some deposits is too small to show at the map scale.  These are indicated by two or more deposits separated by a plus sign (+).  The most common deposit is listed first, for example Qiag+Qoag indicates that both deposits are present and Qiag is more abundant than Qoag.  Other deposits may be present and are less than 20% of the unit area.  Compound units may also be veneers on older deposits.   For instance, the unit Qye+Qae/Qilg indicates that the mixed eolian unit Qye+Qae overlies an older lacustrine unit.
