Description: Abstract: This surficial geologic map covers parts of six 7.5-minute quadrangles that center on the Red Rock Lakes National Wildlife Refuge, southwestern Montana (scale of 1:24,000). An accompanying pamphlet describes 25 map units, their time relationships, and a brief Quaternary geologic history including a table of radiocarbon ages and a table of optically stimulated luminescence (OSL) ages. The Centennial fault is an active basin and range normal (extensional) fault located just above the base of the Centennial Range in the southern part of the map area. Late Cenozoic offset on the Centennial fault has created the Centennial Valley by downward movement on the north side of the fault and the Centennial Range by upward movement on the south side of the fault. In late Pleistocene time, the central part of the map area was the site of Lake Centennial. Lake Centennial was probably created when landslides blocked the old course of the Red Rock River when it previously drained to the northeast through a canyon that is now the site of Elk, Hidden, Cliff, and Wade Lakes. Alluvial fans were built in late Pleistocene time by streams carrying sand and gravel from the adjacent mountains onto the floor of the Centennial Valley. Alluvial deposition built up these fans built outside the margin Centennial Lake and carried finer sediment into the lake. The fans build out subsequently to lower levels as the lake receded. On the downstream margins of the present Upper and Lower Red Rock Lakes, alluvial-fan complexes constrict the valley floor and form fan-dams that hold in the two shallow lakes. Sand dunes occur in the northern part of the map area and a flat (sand sheet) deposit adjacent to the southern margin of the dunes. Sand and gravel beneath the Centennial Lake sediments provide a conduit (aquifer) for ground water that moves toward the center of the basin and seeps upward to sustain wetlands in the central part of the valley, particularly later in the hydrologic year. Purpose: The purpose of the map is to show the surficial geology of the terrain centered on the Red Rock Lakes National Wildlife Refuge. The surficial geology is important to the surface and subsurface hydrology of the wetlands that are a major habitat for the vegetation and wildlife of the Refuge. Lake Centennial that formed in the late Quaternary is important to the soils and hydrology of the Red Rock Lakes area.

Native_Data_Set_Environment: Microsoft Windows 7 Version 6.1 (Build 7601) Service Pack 1; ESRI ArcGIS 10.0.4.4000 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Data were checked by the geologist that made the field observations and compilation. 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. Logical_Consistency_Report: Map elements were visually checked for overshoots, undershoots, duplicate features, polygon closure, and other errors by the authors and by the GIS technician(s) who 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 another geologist and cartographer for consistency with basic geologic principles and general conformity to USGS mapping standards. Completeness_Report: Data are preliminary. No features that could be accurately represented at a scale of 1:24,000 were eliminated or generalized. The smallest area represented is approximately 45 square meters. All geospatial database elements are attributed. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Boundaries (lines) between Quaternary surficial geologic units are approximately located within an indefinite gradational zone between them.
