Medicine Lake volcano forms a broad, seemingly nondescript highland, as viewed from any angle on the ground. Seen from an airplane, however, treeless lava flows are scattered across the surface of this potentially active volcanic edifice. Lavas of Medicine Lake volcano (MLV), which range in composition from basalt through rhyolite, cover more than 2,000 km2 east of the main axis of the Cascade Range in northern California. Across the Cascade Range axis to the west-southwest is Mount Shasta, its towering volcanic neighbor, whose stratocone shape contrasts with the broad shield shape of MLV. Hidden in the center of MLV is a 7 km by 12 km summit caldera in which nestles its namesake, Medicine Lake. The flanks of MLV, which are dotted with cinder cones, slope gently upward to the caldera rim, which reaches an elevation of nearly 8,000 ft (2,440 m). The maximum extent of lavas from this half-million-year-old volcano is about 80 km north-south by 45 km east-west. In postglacial time, 17 eruptions have added approximately 7.5 km3 to its total estimated volume of 600 km3, considered to be the largest by volume among Cascade Range volcanoes. The volcano has erupted nine times in the past 5,200 years, a rate more frequent than has been documented at all other Cascade volcanoes except Mount St. Helens. Purpose: This database was constructed in order to produce a geologic map as a basis for understanding processes and volcano hazards involved in the eruptions of Medicine Lake volcano. Supplemental_Information: All the geologic map information used to publish U.S. Geological Survey Scientific Investigations Map 2927 is contained in this digital publication. This map shows the distribution and relations of volcanic units at Medicine Lake volcano in northern California, including all of Lava Beds National Monument. This metadata document contains information for the entire set of ArcInfo coverages included in this database. Where relevant information for individual coverages differs from that of the others, each coverage is documented separately in sequence in that 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 1:50,000 means that higher resolution information is not present in the dataset. Plotting at scales larger than 1:50,000 will not yield greater real 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. Acknowlegdment of the U.S. Geological Survey would be appreciated in products derived from these data.

Donnelly-Nolan (Donnelly-Nolan, 2010). David W. Ramsey, Tracey J. Felger, Ellen Lougee, and Peggy E. Bruggman provided the GIS-expertise to bring the database and metadata to completion. Native_Data_Set_Environment: SunOS, Release 5.7, sun4u UNIX; Arc Version 7.1.2 Patch 2; ESRI ArcCatalog 8.3.0.800 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: See Entity_Attribute_Information Logical_Consistency_Report: Polygon and arc (chain-node) topology present in appropriate ArcInfo coverages. Other coverages are point, annotation or raster and do not require topologic relationships. Completeness_Report: The report is intended to describe completely the igneous and volcanic products, volcanic vent locations, and structural features of Medicine Lake volcano at 1:50,000 scale. Geological information appropriately mapped at larger scales has been omitted. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Well located data items are intended to have a horizontal positional accuracy better than 0.5 mm at 50,000 scale, or within 25 meters on the ground. The general positional accuracy of each line in the database is indicated qualitatively within the LTYPE field in the Arc Attribute Table (see Attribute_Domain_Values). Points in the database are generally well located. The position of each data item is derived from a USGS 1:24,000 topographic base map, and therefore additional inaccuracies may also be encountered that are within National Map Accuracy Standards. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: No vertical positional data recorded Process_Step: Process_Description: Geologic linework was compiled on USGS 1:50,000-scale, 1:48,000-scale, and 1:24,000-scale topographic maps by Julie M. Donnelly-Nolan. The linework was then scanned at 400 dpi, georeferenced, converted to vector data using the ArcInfo command GRIDLINE , and edited on-screen to repair errors visible at map scale by David W. Ramsey, Tracey J. Felger, Ellen Lougee, and Peggy E. Bruggman. Polygon topology was created and each arc and polygon tagged on-screen. Plotfiles were created in ArcPlot by David W. Ramsey. Individual quadrangles were then plotted with topography and checked by Julie M. Donnelly-Nolan. Metadata were created by David W. Ramsey.

The lines define the boundaries of the map units and other delineated polygons as well as linear features such as but not limited to, faults, lava tubes, and moraine crests. These distinctions, including geologic characterizations of linear features, are recorded as attributes in the LTYPE field in the AAT. Map units (polygons) are described in a polygon attribute table ("filename".PAT). The identities of the map units from compilation sources are recorded in the PTYPE field of the PAT by unit symbol. Note that ArcInfo coverages cannot contain both polygon and point information, so only coverages with polygon information will have a polygon attribute table, and these coverages will not have a point attribute table. Files containing point features are described in a point attribute table ("filename".PAT). Examples of point features include volcanic vents and geothermal drillhole locations. Almost all of the attributes in the various attribute tables included in the report are set or calculated by ArcInfo and include "filename"#, "filename"-ID, LENGTH, FNODE, TNODE, RPOLY, LPOLY, AREA, and PERIMETER. The rest are defined by the author as described above and include LTYPE, PTYPE, PTTYPE, LATITUDE, LONGITUDE, and DRILLHOLE.
