Lead-rich sediments, Coeur d'Alene River valley, Idaho; Area, volume, tonnage, and lead content: Geologic and wetland unit data

This metadata file (cdafldpl.met) describes three shape files.
Shape file cdasurf4_utm.shp, with its associated .shx and .dbf files,contains polygons and attributes for a map of geologic and wetlandunits and systems, which represent sedimentary depositionalenvironments of the Coeur d'Alene (CdA) River valley. This map extendsbeyond the lateral and longitudinal boundaries of the area studiedfor this report.
Shape file fldpln2.shp was derived from shape file cdasurf4.shp bytrimming it to the study area for this report, which includes theCdA River channel and floodplain, from the confluence of its Northand South forks, to the base of its delta, in CdA Lake.
Shape file fpaream2.shp was derived from fldpln2.shp by merging its1544 polygons into one polygon, representing the 85 square-kilometerarea studied for this report.
