  Description:
    Abstract: Debris flows, debris avalanches, mud flows and lahars are 
      fast-moving landslides that occur in a wide variety of environments
      throughout the world.  They are particularly dangerous to life and
      property because they move quickly, destroy objects in their paths,
      and can strike with little warning.  The purpose of this map is to 
      show where debris flows have occurred in the conterminous United
      States and where these slope movements might be expected in the 
      future. 
    Purpose: These data are intended for geographic display and
      analysis at the national level, and for large regional
      areas.  It is not intended for hazard evaluation or other 
      site-specific work, and should not be used for such.  It can
      be used to determine where debris flow processes may be a
      problem and where additional information and investigation are
      warranted.  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 at a scale of
      1:2,500,000 means that higher resolution information is not
      present in the data.  Plotting at scales larger than
      1:2,500,000 will not yield greater real detail, and 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.  No responsibility is assumed by the U.S.
      Geological Survey in the use of these data.

      All of the data on this map were compiled from reports published
      or field work conducted after the year 1928.

      No distinction was made between debris flow scars, made shortly
      after the events and debris flow deposits, which may be thousands
      of years old. We believe that all of the debris flows described
      in this report formed during the past 10,000 years (Holocene),
      but some of them could be older.

  Data_Set_Credit: We are grateful to several state geologists
    and members of their staff who kindly reviewed a preliminary
    copy of the map and the bibliography and provided new information.
    We are particularly grateful to M. Lee Allison, State Geologist
    for Utah, and members of his staff who contributed a digital
    database of debris flow locations for Utah. We also wish to thank
    Stephen Ellen, Russell Campbell, Gerald Wieczorek, and David
    Howell for their reviews and help during various phases of the work.
  Native_Data_Set_Environment:
    The databases in this repot were compiled in ARC/INFO, a commercial
    Geographic Information System (Environmental Systems Research
    Institute, Redlands, California), with version 3.0 of the menu
    interface ALACARTE (Fitzgibbon and Wentworth, 1991, Fitzgibbon,
    1991, Wentworth and Fitzgibbon, 1991).  The files are in either
    GRID (ARC/INFO raster data) format or COVERAGE (ARC/INFO vector
    data) format.  Coverages are stored in uncompressed ARC export
    format (ARC/INFO version 7.x).  ARC/INFO export files (files with
    the .e00 extension) can be converted into ARC/INFO coverages in
    ARC/INFO (see below) and can be read by some other Geographic
    Information Systems, such as MapInfo via ArcLink and ESRI's ArcView
    (version 1.0 for Windows 3.1 to 3.11 is available for free from
    ESRI's web site:  http://www.esri.com). The digital compilation was
    done in version 7.0.4 of ARC/INFO with version 3.0 of the menu
    interface ALACARTE (Fitzgibbon and Wentworth, 1991, Fitzgibbon,
    1991, Wentworth and Fitzgibbon, 1991).
Data_Quality_Information:
  Logical_Consistency_Report: No additional checks for
    topological consistency were performed on this data set.
  Completeness_Report:  This data set includes an inventory of debris
    flows and related fast-moving landslides for the conterminous United
    States, and a susceptibility map covering the same area. This
    inventory is up-to-date as of August 1999, but there undoubtedly
    exists a significant amount of information that is not included in
    this report.
  Lineage:
    Process_Step:
      Process_Description:
        Best and Brabb prepared an inventory of past debris flows in
        1984 using data from the reconnaissance field investigations
        and published and unpublished reports, a list of which was
        eventually published by Alger and Brabb (1985). This 
        information was plotted on 1:500,000-scale USGS state maps
        and transferred by hand to a 1:2,500,000-scale greenline
        base map of the United States.

      Process_Description:
         In 1997, this greenline base map was scanned and registered
         by A. Barron and M. Sinor. The registered map was edited and
         digitized using ARC/INFO, and the REF database field was
         completed. No new information was added to the map at that time.

    Process_Step:
      Process_Description:
        In 1998 and 1999, new information was added to bring the map
        up-to-date. The data were gathered from published and unpublished
        reports of debris flows primarily covering the years 1984 -1999.
        A few older reports were included that had been overlooked in the
        original map. In addition, all state geologists were contacted to
        find out if they had information on debris flows. Several state
        geologists and members of their staff provided significant new
        information.

        If a report included a map at a scale larger than that of the
        compilation (1:2,500,000), the map or a photocopy was scanned.
        Other reports contained only the names of places where debris
        flows had occurred, or a map at a scale smaller than 1:2,500,000,
        or a map with no geographic coordinates. In those cases, the
        debris flows were located on the appropriate 1:500,000-scale
        USGS state map or a 1:100,000-scale USGS topographic map and
        plotted by hand on a Mylar overlay. This overlay was then
        scanned.

        The scanning was done at 400 dpi on either a UMAX color flatbed
        scanner or a Contex FSC-8000dsp color scanner, depending on the
        size of the map or tracing.  The scanned images were transformed
        from scanner coordinates to geographic coordinates in ARC/INFO
        with digital tics placed by hand.  The scanned lines and/or
        points were edited interactively using ALACARTE (Wentworth and
        Fitzgibbon 1991), and the database fields (Tables 3 and 4) were
        filled in as appropriate. In addition, a new database field
        (table 5) was added to store the name of the state under which
        the report for a feature on the map was referenced.

    Attribute:
      Attribute_Label: REF
      Attribute_Definition: The reference number(s) for a point or
        polygon, which refers to an entry in the bibliography for
        that state
      Attribute_Definition_Source: USGS MF-2329
      Attribute_Domain_Values:
        Unrepresentable_Domain: There is no predefined set of
          valid reference numbers. Because multiple published and
          unpublished reports can refer to the same geographic area,
          a single point or polygon may contain many reference numbers.
          Multiple points or polygons may also contain the same
          reference number, since a single report may refer to multiple
          locations. Each points or polygon has a list of numbers,
          comma-delimited, with no spaces, that indicate every report
          in the bibliography which contains information for that
          location.
