Arthur A. Bookstrom and Stephen E. Box mapped the surficial geology and wetland system units (1996-1998); Berne L. Jackson (Coeur d'Alene Tribe) scanned the original stable-base 1:24,000-scale maps and created and attributed the GIS with preliminary labels and linecodes. Theodore R. Brandt (contractor) created the master Arc/Info registration file and converted the preliminary GIS to Idaho state plane format. He also digitized in new linework, edited the digital files, and built lookup tables with detailed wetland system, geologic, lithologic, and metal contamination information; Pamela D. Derkey (USGS) provided technical assistance with the geologic-wetland systems data model, metadata, digital documentation, and map projections; Steven R. Munts (contractor) assisted with digital editing; Julie Campbell (USFW) reviewed marsh and lacustrine systems for correctness. She also reviewed vegetation classes and subclasses.
The purpose of these GIS datasets is to show how the distribution of floodborne contaminated sediments is related to potential sources of clean and contaminated sediments, and to hydrologic features that determine patterns of erosion, transport, and deposition. Mapped geologic information indicates the configuration and distribution of surficial geomorphic features and sedimentary deposits that result from erosion, transport, and deposition of unconsolidated sediments. Mapped wetland features indicate the configuration and distribution of surficial hydrologic pathways that guide erosion, transport, and deposition. These GIS datasets are intended to aid in process- oriented interpretation of geochemical and biological data being collected as a basis for natural-resource damage assessment and restoration planning.
