AN EXAMPLE OF VIRTUAL AND REAL WORLD FLAGGING IN A GEOLOGY FIELD CAMP MAPPING PROJECT FROM DEADMAN GULCH, BLACK HILLS, SOUTH DAKOTA

The Eastern Illinois University Geology Field Camp incorporates several geologic mapping projects at various locations in the Black Hills of South Dakota. The Deadman Gulch mapping project is a multiple day geologic exercise in heavily wooded, rugged terrain that contains outcrops of multiple lithologies representing several different chronostratigraphic systems. Many geologic contacts and features are difficult to find in the field. A trail to observe several key features was developed and flagged by the faculty to facilitate students locating these features for their map projects.

Digital images are used to provide an online enhancement to this mapping project by showing the geologic features observable via the world wide web. This affords students the opportunity to make sure that they observe the correct feature on their individual traverse through a portion of the map area; however this web enhancement does not reveal the locations of the features that students must plot on their base map.
