(Sheet 2 of Map I-2005 shows sources of geologic data used in the compilation and is available separately). This map is one of a series that shows Cascade Range geology by fitting published and unpublished mapping into a province-wide scheme of lithostratigraphic units. Geologic maps of the Cascade Range in California and Oregon complete the series, providing a comprehensive geologic map of the entire Cascade Range that incorporates modern field studies and that has a unified and internally consistent explanantion. The complete series will be useful for regional studies of volcanic hazards, volcanology, and tectonics. Purpose: Originally a project supported by the Geothermal Research Program of the U.S. Geological Survey, this map emphasizes Quaternary volcanic rocks, because large igneous-related hydrothermal systems that have high temperatures are associated with Quaternary volcanic fields. Rocks older than a few million years are also included on the maps as they help to unravel geologic puzzles of the present-day Cascade Range. The deeply eroded older volcanoes found in the Western Cascades physiographic subprovince are analogues of today's snow-covered shield volcanoes and stratovolcanoes. The fossil hydrothermal systems of the Eocene to Pliocene vents now exposed provide clues to processes active today beneath the Pleistocene and Holocene volcanic peaks along the present-day crest of the Cascade Range. Study of these older rocks can aid in developing models of geothermal systems. These rocks also give insight into the origins of volcanic-hosted mineral deposits and even to future volcanic hazards. Supplemental_Information: Geologic map information used to publish U.S. Geological Survey Miscellaneous Investigations Series Map I-2005 is contained in this digital publication. Sheet 1 in Map I-2005 shows the distribution and relations of volcanic and related rock units in the Cascade Range of Washington at a scale of 1:500,000. This digital release is produced from stable base materials originally compiled at 1:250,000 scale that were used to publish Sheet 1. The database therefore contains more detailed geologic information than is portrayed on Sheet 1. No stable base materials were available for Sheet 1 at 1:500,000 scale. This metadata document contains information for the entire set of ArcGIS feature classes included in this database. Where relevant information for individual feature classes differs from that of the others, each feature class is documented separately in sequence in the corresponding metadata section.

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 for a scale of 1:250,000 means that higher resolution information is not present in the dataset. Plotting at scales larger than 1:250,000 will not yield greater detail, although 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. Acknowledgement of the U.S. Geological Survey would be appreciated in products derived from these data.

Barron from original stable source materials compiled by James G. Smith (Smith, 1993). David W. Ramsey converted the database from Arc/Info coverage format to ArcGIS 9.3.1 geodatabase format for release. David W. Ramsey created the metadata. Andrew D. Barron and David W. Ramsey provided the GIS-expertise to bring the database and metadata to completion. Native_Data_Set_Environment: Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 3; ESRI ArcCatalog 9.3.1.3000 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: See Entity_Attribute_Information Logical_Consistency_Report: Polygon and arc (chain-node) topology present in appropriate ArcGIS feature classes. Other feature classes are point or line exclusively and do not require topologic relationships. Completeness_Report: The report is intended to describe completely the spatial extents of volcanic and related rocks and structural features of the Cascade Range, Washington. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The general positional accuracy of each line in the database is indicated qualitatively within the "type" fields in the attribute tables of each line feature class (see Attribute_Domain_Values). Points in the database are generally well located. The position of each data item is derived from USGS 1:250,000-scale topographic base maps, and therefore inaccuracies encountered are within National Map Accuracy Standards at that scale. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: No vertical positional data recorded Process_Step: Process_Description: Geologic linework was compiled on USGS 1:250,000-scale topographic maps by James G. Smith. The linework was then scanned at 400 dpi, georeferenced, converted to vector data, and edited on-screen to repair errors visible at map scale by Andrew D. Barron. Linework was smoothed and generalized to accurately represent geologic features by Andrew D. Barron using methods and tolerances developed by Carl Wentworth and Todd Fitzgibbon for their geologic map editing interface ALACARTE. Polygon topology was created and each arc and polygon were tagged on-screen by Andrew D. Barron. The database was converted from ArcInfo coverage format to ArcGIS 9.3.1 geodatabase format by David W.
