Field Trips Linked to Theme Sessions:

1. Geology of the Homestake Gold Mine (Deep Underground Science and Engineering Lab [DUSEL]) in Lead, South Dakota.
Colin Paterson
Tues., 20 April 2010. Min.: 8; max: 20. Fee US$55.
Stratigraphy, structure, mineralization and experiments underground (half-day); surface geology (half-day). NOTE: Underground tour is contingent upon DUSEL approval, and could be subject to last-minute cancellation if conditions warrant.
2. Structural and Tectonic Evolution of the Proterozoic Trans-Hudson-Archean Wyoming Province Boundary.
Michael P. Terry, Jack Redden, Edward F. Duke, Stephen J. Allard
Sat.-Sun., 24-25 April. Min.: 9; max.: 18. Fee: US$170.
This two-day trip examines the Precambrian stratigraphy, petrology, and structure of rocks exposed in the core of the Laramide-age Black Hills uplift. The field trip will focus on the Paleoproterozoic deformation, magmatic, and tectonic events that have modified these rocks.
3. Karst and Fractured Aquifer Hydrogeology: Recent Advances in the Conceptualization, Characterization, and Interpretation of Fluid Movement and Transport Dynamics.
Larry D. Putnam
Tues., 20 April. Min.: 10; max.: 25. Fee: US$60.
This field trip covers Rapid City and adjoining areas west to Johnson Siding and northwest to Nemo. The primary emphasis of the trip is the hydrogeologic characteristics of the Madison Limestone, and additional stops will address groundwater contamination within the Precambrian terrain.

5. Laramide Tectonics and Stratigraphy of the Northern Rocky Mountains and Great Plains.
Alvis Lisenbee, Eric Erslev
Sat.-Sun., 24-25 April. Min.: 10; max.: 30. Fee: US$175.
The two-day field trip examines the contrasting structural styles of the east (half dome) and west (monoclinal) flanks of the Black Hills uplift. It also utilizes the nature of pre-, syn-, and post-tectonic sedimentary units in defining the timing of deformation for this easternmost of the Laramide uplifts of the northern Rocky Mountains.
6. Recent Advances in Understanding the Geologic History of the White River Badlands.
Emmett Evanoff, Patrick Burkhart, Rachel Benton
Sat.-Sun., 24-25 April. Min.: 13; max.: 30. Fee: US$135.
The South Dakota Badlands contain the most fossiliferous terrestrial rocks in all of North America. We have been studying the fascinating geomorphologic history, detailed paleontology, stratigraphy, and paleopedology of the White River Group in Badlands National Park during the past decade, and have new insights as to its origin, timing, and environments. The Quaternary erosional history of the Badlands Wall and the associated eolian deposits are also beginning to be understood. This two-day trip will examine the late Eocene and Oligocene features of the White River Group (first day), and the Quaternary deposits and erosional history (second day).
11. Paleozoic Stratigraphy of the Northern Black Hills.
Mark Fahrenbach
Tues., 20 April. Min.: 8; max.: 20. Fee: US$60.
Paleozoic rocks from Cambrian to Permian are well exposed in the northern Black Hills. This one-day field trip will cross the northern portion of the Black Hills uplift, including the Lead-Deadwood dome, and travel down scenic Spearfish Canyon. Stops will be made at many localities to examine the Paleozoic stratigraphy, as well as the Precambrian-Cambrian unconformity.
