Description Abstract This data set shows the boundaries for the Case 2 debris flow or debris avalanche zone for Mount Rainier (Scott and Vallance, 1995). The lines in this data set encompass several polygons each labeled for inclusion or exclusion in the zone. Six registration marks lie outside the polygons. The coverage is in the universal transverse mercator projection.

Keywords: None.

Purpose This data set is intended for analysis, planning, and making maps of hazards. The polygon boundaries do not mark a distinct change between hazard and no-hazard areas. The degree of hazard decreases with increase of distance or elevation outside the boundary. Because debris flows and debris avalanches are complex phenomena and they are the major volcanic hazard at Mount Rainier, it is recommended that users read Hoblitt and others (1995) and Scott and Vallance (1995) prior to using this data.

Supplemental_Information Procedures_Used A stable base map with linework was obtained from the authors. Latitude, longitude registration ticks were added to the base and used to orient the map on a digitizing tablet. Linework was collected in ArcEdit with digitizer inch units, a weed tolerance of 0, and a nodesnap set to closest 0.05 inches. A second coverage was created from the original. The decimal degree latitude and longitude values were substituted for the digitizer inch values in the second coverage. The second coverage was reprojected to a UTM projection with parameters of zone 10, units in meters, and a spheroid of Clarke 1866. The original coverage was transformed to the second projection to create a coverage in meters. RMS values were inspected during the transformation. After digitizing was complete the final coverage was plotted at the same scale as the base map, overlain in the basemap and checked for errors. The data set was brought up in ArcEdit with polygons of the Puget Sound from 1:100000 scale DLG data as a background coverage to guide closing of some polygons. These additional lines are NOT part of the original data, they are coded as indicated in the above section. The data set was renamed to rnr2lahar for Mount Rainier Case 2 debris flow and debris avalanche zone hazard.

Overview_Description Entity_and_Attribute_Overview Polygons were given an attribute (item SYMBOL) to indicate whether they are included (CODE = 1) or excluded (CODE = 0) from the debris flow and debris avalanche zone. These attributes were added to the polygon attribute table (RNR2LAHAR.PAT). Lines (polygon boundaries) were given an attribute (item LCODE) to show differences in line types gleaned from the original map: LCODE LINE TYPE 0 solid lines on the original map 1 dashes on original map 99 NOT part of original map linework; straight line added to close polygon Lines (polygon boundaries) were given a second attribute (item EVENT) to indicate the debris flow case they represent. Rnr2lahar boundaries are coded as part of case 2 (EVENT = 2) or as added to close polygons (EVENT = 0).
