Most of the Front Range is composed of Proterozoic rocks ranging in age from 1,790 Ma to 1,074 Ma. Along the eastern flanks and within the Denver Basin, sedimentary rocks ranging from Pennsylvanian to Cretaceous are deformed and steeply tilted to the east. Upper Cretaceous through Paleocene rocks were deposited in the foreland (i.e., the Front Range eastern flank) and hinterland (i.e., South Park) of this thrust and reverse fault system developed during the Late Cretaceous to Paleocene Laramide orogeny. Within South Park, rocks range in age from Pennsylvanian to Miocene with Quaternary deposits indicating tectonic subsidence of the basin. These rocks record five major geologic episodes: (1) the Paleozoic Anasazi uplift that formed the Ancestral Rockies, (2) the Late Cretaceous to Paleocene Laramide orogeny, (3) widespread Eocene to Oligocene volcanism, (4) Oligocene-Quaternary tectonics, and (5) Quaternary glacial episodes. Purpose: Land-use planners of many kinds (including National Forest managers, developers, city and rural planners, and highway builders) need accurate geologic data with which to make informed decisions. The Bailey quadrangle is designed to meet this requirement. The map is also part of the National Geologic Database, intended as digital framework for the entire country. From a scientific standpoint, the map clarifies many structural and lithologic relationships in the complex Proterozoic basement of the Colorado Front Range and portrays structural and stratigraphic features on both the east and west side of the range, especially within South Park where complex subsurface structures have not been well understood.

Digital compilation by Cal Ruleman. Paco Van Sistine provided keen insight for creating a proper digital database for future use in many applications and assisted with editing the digital version. Native_Data_Set_Environment: Microsoft Windows XP Version 5.1. ArcMap/ArcInfo version 9.2 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Data were entered by GIS technician and authors 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 symbolized. Logical_Consistency_Report: Map elements were visually checked for overshoots, undershoots, duplicate features, polygon closure, and other errors by the author and by the GIS technician(s) that created the digital database. Automated 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 two other geologists for consistency with basic geologic principles and general conformity to USGS mapping standards. Completeness_Report: Data are complete. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Lines were mapped from previous map publications, unpublished reconnaissance mapping, and new original mapping at 1:24,000 scale. In addition to field mapping, photo interpretation of 1:20,000-scale black and white aerial photgraphs and Landsat imagery assisted with line placement. Lines were digitized from 1:24,000-scale topographic field sheets. Individual point positions were measured and determined with a GPSmap 60CSx with a horizontal accuracy of 1-3 m. Most digitized line positions have an accuracy of 20-30 m. Lineage: Source_Information: Source_Citation: Citation_Information: Originator: Barker, F. Originator: Wyant, D.G.
