This map shows debris flow hazard areas in the United States, including locations of known debris flows and predictions of where future flows might occur. It shows the locations of debris flows in two different ways, as points representing the locations of individual flows or small groups of flows, and as areas or polygons containing one or more debris flows. Different symbols are used to indicate uncertainty in location or the identification of the feature as a debris flow. The map comes in two sheets and is available as downloadable Postscript (.ps) or Portable Document Format (.pdf) files. It is accompanied by an explanatory pamphlet. Areas of susceptibility to future debris flows are shown in a georeferenced TIFF file that can be opened in an image editing program or imported into a GIS system like ARC/INFO. Other datasets are in ARC/INFO export format.
