Attempts have been made to reproduce all aspects of the original source products, including the geologic units and their descriptions, geologic cross sections, the geologic report, references and all other pertinent images and information contained in the original publication. This document contains the following information: 1) About the NPS Geologic Resources Inventory Program – A brief summary of the Geologic Resources Inventory (GRI) Program and its products. Included are web links to the GRI GIS data model, and to the GRI products page where digital geologic-GIS datasets, scoping reports and geology reports are available for download. In addition, web links to the NPS Data Store and GRI program home page, as well as contact information for the GRI coordinator, are also present. 2) GRI Digital Maps and Source Citations – The citation of the GRI digital geologic-GIS map produced for this project along with the source map used in its completion. In addition, an index map and a brief explanation of how the source map was used is provided. 3) Map Unit Listing – A listing of all geologic map units present on the map for this project, generally listed from youngest to oldest. 4) Map Unit Descriptions – Descriptions for all geologic map units. 5) Ancillary Source Map Information – Additional information present on the source map. 6) GRI Digital Data Credits – GRI digital geologic-GIS data and ancillary map information document production credits.
