The oldest rocks in the quadrangle include gneiss, schist, and plutonic rocks of Paleoproterozoic age that are intruded by younger plutonic rocks of Mesoproterozoic age. These basement rocks are exposed along the southern, eastern, and northern margins of the quadrangle. Fluvial claystone and mudstone of the Upper Jurassic Morrison Formation, and fluvial sandstone and conglomeratic sandstone of the Lower Cretaceous Dakota Group, primarily overlie Proterozoic rocks in a small area near the southwest corner of the quadrangle. Oligocene rhyolite tuff is preserved in deep paleovalleys cut into Proterozoic rocks near the southeast corner of the quadrangle. Generally, weakly consolidated siltstone and minor unconsolidated sediments of the upper Oligocene to upper Miocene Troublesome Formation are preserved in the post-Laramide Fraser basin. Massive bedding and abundant silt suggest that loess or loess-rich alluvium is a major component of the siltstone in the Troublesome Formation. A small unnamed fault approximately 1 kilometer northeast of the town of Winter Park has the youngest known displacement in the quadrangle, displacing beds of the Troublesome Formation. Low-lying areas along major and minor streams are subject to periodic stream flooding. Mass-movement deposits and sediments of the Troublesome Formation, that underlie moderate to steep slopes, are locally subject to sheet flooding, gullying, creep, debris-flow deposition, and landsliding. Rhyolite tuff, that underlies steep slopes, is locally subject to rockfall. Surficial deposits of Pleistocene and Holocene age are widespread in the Fraser, Colo. quadrangle, particularly in major valleys and on slopes underlain by the Troublesome Formation. Deposits include glacial outwash and alluvium of non-glacial origin; mass-movement deposits transported by creep, debris flow, landsliding, and rockfall; pediment deposits; tills deposited during the Pinedale and Bull Lake glaciations; and sparse diamictons that may be pre-Bull Lake till or debris-flow deposits. Some of the oldest surficial deposits may be as old as Pliocene. Sand and gravel resources for construction and other uses in and near the Fraser quadrangle are present in outwash-terrace deposits of middle and late Pleistocene age along the Fraser River and its glaciated tributary streams. Purpose: This map provides geologic information for making land-use decisions and evaluating subsurface water resources. The map was funded by the National Cooperative Geologic Mapping Program of the U.S. Geological Survey.

Native_Data_Set_Environment: Windows_XP, Intel ArcInfo version 9.3.1 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Data were entered and checked by the geologist that made the field observations. The attributes of this geospatial data set consist of text identifiers and numeric codes that indicate the identity of the geologic unit or type of geologic feature, and determine how each feature is colored or symbolized. To check attribute accuracy, a color check plot was visually compared to the geologist's original compilation. Discrepancies between the digital geospatial dataset and the original analog or digital compilation were corrected as needed. Machine-created listings of unique attribute values were used to identify spelling errors or other inconsistencies, and corrections were made as needed. Logical_Consistency_Report: Map elements were visually checked for overshoots, undershoots, duplicate features, polygon closure, and other errors by the lead author and by the GIS technician(s) that created the digital database. Automated (ArcInfo) routines were also used to check the databases for polygon label errors, line or point attribution errors, sliver polygons, dangling arcs, intersection errors, and projection information. Check plots of the map were reviewed by at least one other geologist for consistency with basic geologic principles and general conformity to USGS mapping standards. Completeness_Report: Data are complete: no features that could be accurately represented at the compilation scale of 1:24,000 were eliminated or generalized. The smallest area represented is approximately 110 square meters. All geospatial database elements are attributed. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Most digitized positions on the map that depict distinct contacts between rock formations in the field are estimated to be within 20 m of the actual contact on the land in most instances. Boundaries (lines) between Quaternary units (for example, terrace gravels) that correspond closely to distinct edges of landforms (for example, river terraces) are of comparable accuracy. Boundaries (lines) between some Quaternary units, such as eolian deposits and broad alluvial aprons, are approximately located within an indefinite gradational zone between them. Horizontal positional accuracy is tested by visual comparison of hard copy test plots to source maps or comparing locations of data on a computer monitor to other data layers in the same geographic area. The database contains no elevation data. Accuracy of these digital data indirectly depends on accuracy of the base maps on which the original source geologic maps were compiled. These base maps were made by the U.S. Geological Survey, which routinely checks them for compliance with the National Map Accuracy Standards.

DATABASE STRUCTURE - ArcInfo ==================================== This GIS database includes related look-up tables, which store detailed attribute information. This database structure is more fully described in USGS OFR 99-438 (Lewis and Derkey, 1999). The GIS database structure used in the database includes symbol and pattern items in coverage point, polygon (PAT), and arc (AAT) attribute tables for user convenience. ArcInfo relates for each coverage are saved in a file named .rel. Use the RELATE command with the restore argument at the arc prompt to make the relates active. Alternatively, in ArcTools, use the Relate environment: open dialog in the Manage Relates flyout menu under the ArcTools menu to make the relates active. frasgeo coverage: Contains all contact lines and label points for each geologic polygon. In the .pat INFO file the SOURCE item provides a numeric code used to identify the data source for the rock unit. Complete references for the sources listed are listed in the frasgeo.ref file. The LABEL item indicates the rock unit label (abbreviation) used to label unit on map. The MLABEL item indicates the rock unit label from GeoAge version 1.2 font, using geologic age letter symbols associated with the age of the lithologic units (for example: Triassic, Pennsylvanian, Cambrian). The DESC item defines formal or informal unit name. The SYMBOL item contains the shadeset symbol number used by ArcInfo to plot a filled/shaded polygon. The symbol numbers in this item refer to the wpgcmykg.shd shadeset included with the dataset. The PATTERN item contains the pattern number used in the published version of the map.
