Poster: Geologic Map of the Colonial Beach South 7.5' Quadrangle, Virginia

The Open-File Report includes a geologic map with cross section, and composite stratigraphic section of the Tertiary stratigraphy and of the Quaternary stratigraphy. The Tertiary map units are presented and interpreted for erodability and derived surficial deposits.

The map area contains the George Washington Birthplace National Monument. The map facilitates the interpretation of the natural history of the Park including processes such as bog (wetlands) formation and coastal erosion. Two cores of Holocene estuarine deposits are sited on the map. They present the transition from terrestrial to estuarine depositional environments.

This report is available in Adobe Reader PDF format (2.5 MB). Right-click (PC) or Control-click (Macintosh) to download the map. To download Acrobat Reader software, please visit the Adobe website.
