Additionally, the geologic map portrays faults, if present, as well as other lineaments that represent either faults or erosional features. Purpose: This series of maps supplements an earlier series of similar maps for the adjacent area to the south between Palmer and Big Lake. A separate geologic-materials map was developed to show the probable distribution of materials with certain ranges of grain sizes, and their relative abundance, because the area is rich in geologic materials that may be useful for construction. It is an important source of construction aggregates for the region, because of extensive glaciofluvial deposits in the area. Additionally, the Castle Mountain fault, which is known to be active, traverses the area of the current series of maps. Although the fault is easily distinguishable in areas immediately to the east and west of the area mapped in this series, it is largely obscured here by surficial deposits and vegetation. We present on these maps the best known surface evidence for faults and possibly fault-related lineaments. Supplemental_Information: The layers listed below are present as ArcGIS shape files. Attribute information for the following layers (entities) is included in this metadata file under the "Entity_and_Attribute_Information" section.

The surficial-geologic information was transferred from acetate air-photo overlays to a paper 1:63,360-scale USGS topographic base using a zoom transfer scope. The surficial-geologic information was then digitized into Arc/Info GIS (ArcEdit module) using a large-format digitizing table with RMS registration errors constrained to be no larger than 0.003 inches (input coverage units) for each digitizing session. Geologic data included in the compilation are the field maps and notes from this project as well as data from other sources as noted in the "Sources Cited" section. Logical_Consistency_Report: Polygon topology present and clean on appropriate data. Other data are line, point, or annotation data and do not require topologic relationships. Chain-node topology present. Completeness_Report: This dataset includes geospatial information related to geologic units, age and field sample locations, structural features, structural measurements, and fault locations. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Location data were determined visually using topographic maps at a scale of 1:63,360 and 1:50,000 (nominal) scale, and color-infrared aerial photographs. Quantitative_Horizontal_Positional_Accuracy_Assessment: Horizontal_Positional_Accuracy_Value: 10 Horizontal_Positional_Accuracy_Explanation: Surficial-geologic map data have a horizontal positional accuracy dependent on: (1) the 1:50,000-scale (nominal) aerial photographs on which they are based, with an estimated potential error due to a pen line width of approximately 0.001 being equivalent to approximately 1.5 meters on the ground; (2) the accuracy of the human zoom transfer scope operator in tracing the linework from acetate overlays to topographic base maps, with an estimated error due to a pen line width of approximately 0.001 being equivalent to approximately 1.5 meters on the ground; (3) the accuracy of the zoom transfer process itself, error magnitude highly variable and unknown but potentially large; (4) the digitizing RMS error of 0.003 inches [input coverage units], which equates to approximately 5 meters on the ground for a 1:63,360-scale map; and (5) the accuracy of the human operator digitizing the geologic linework from the topographic base maps, with an estimated error due to a pen line width of approximately 0.001 being equivalent to approximately 1.5 meters on the ground. Total potential horizontal error for surficial-geologic map features is therefore estimated to be approximately 10 meters.

The geologic map was developed by first interpreting landforms and photolineaments on color and false-color infrared photographs. These deposits and features were then verified, described, and sampled during field inspections. Additionally, information on bedrock geology was compiled from the literature and verified and mapped in the field. Finally, the bedrock and surficial geology were combined into a single draft map and digitized. The geologic-materials map was derived digitally from the geologic map on the basis of field observations that indicate that each geologic unit has a definite composition or range of composition. Therefore, the delineation of materials units was interpreted from the geologic map by using a simple conversion matrix to combine and translate geologic units into materials units. Much of the initial landform interpretation and mapping of geologic contacts and lineaments resulted from analysis of color and false-color infrared vertical aerial photographs. Color aerial photographs used in this interpretation were taken in 1973, 1981, 1982, and 1986 at scales of 1:12,000, 1:18,000, and 1:24,000. False-color infrared images were collected by NASA in 1984 and 1993 at a scale of approximately 1:60,000. Bedrock-geologic data were compiled from the following sources: Clardy (1984), Csejtey and others (1978), Csejtey and others (1979), Csejtey and Smith (1975), Madden and others (1987), Magoon and others (1976), Ray (1954), Silberman and others (1978), and Winkler (1992). Field work was conducted in 1980, 1981, 1988, 1993, and 1994 to verify photointerpretation, map bedrock-unit contacts, and examine the deposits to accurately describe their content. Finally, the draft geologic map units were digitized using geographic information system (GIS) software. The resulting polygons were assigned appropriate colors, labeled, and layered with a digital image of the corresponding U.S. Geological Survey topographic quadrangle map to produce the published geologic map. The USGS topographic base map was produced in 1979 and revised in 1993.
