PREMEETING

1. Silurian Stratigraphy across the Cincinnati Arch: Recalibrating the Layer Cake.
Cosponsored by the Society for Sedimentary Geology (SEPM)-Great Lakes Section.
Tues.-Wed., 22-23 April.
Bradley D. Cramer, The Ohio State University; Patrick I. McLaughlin, Wisconsin Geological and Natural History Survey; Mark A. Kleffner, The Ohio State University at Lima; Carlton E. Brett, University of Cincinnati.
This two-day field trip will examine Llandovery and Wenlock strata exposed on either side of the Cincinnati Arch. Participants will traverse the arch, beginning in southern Ohio and ending at the NCGSA meeting in Evansville. Localities will include both road cuts and quarry exposures demonstrating (1) the facies distribution and sequence stratigraphic architecture on both sides of the arch, (2) the position and signature of major unconformities, (3) the abundance of mineralized and iron-rich horizons, (4) timing and distribution of bioherm growth during the lower Silurian, and (5) the implications for eustasy and tectonism.
Cost: US$50; includes transportation, lunches, and handout. Participants will be responsible for breakfast, dinner, and lodging costs. Min.: 10; max.: 30.
2. Building Stones and Cultural Geology of Evansville.
Cosponsored by the Central Section of the National Association of Geoscience Teachers
Wed., 23 April.
Joe Hannibal, Cleveland Museum of Natural History; Sabina Thomas, Baldwin-Wallace College.
Participants will explore a variety of historic buildings and sites in Evansville that show the development of the city over time with an eye to the use of various kinds of building stone, both local and imported. We will also visit Reitz School, which is located above an old coal mine, and Oak Hill Cemetery, a classic garden-style cemetery located on a hilly outlier of loess.
Cost: professionals, US$36; student and K-12 educators, US$25; includes transportation, handout, and snack (lunch is on your own). Min.: 6; max.: 22.


DURING THE MEETING

3a/3b. The Geological Legacy of New Harmony, Indiana.
Friday morning (3a) or Friday afternoon (3b), 25 April.
Tom Straw, New Harmony, Indiana.
David Dale Owen established his geologic headquarters in New Harmony from 1835 until his death in 1859. During that period, he did most of his work in the former Rappite Granary, which is now restored and known as the Rapp-Owen Granary. The trip will visit this structure, the Owen Laboratory, and the Working Men's Institute—the last vestige of 144 such institutes established from a bequest by William Maclure who is often referred to as "the father of American geology."
Cost: US$20; includes transportation and handout. Min.: 10; max.: 30.


POSTMEETING

4. Quaternary Geology of the Evansville-Henderson area for K-12 Teachers.
Sat., 26 April.
This trip has been canceled.
5. Hydrogeology of an Abandoned Mine Land Site for Management of Coal Combustion Byproducts.
Sat., 26 April.
Paul K. Doss, University of Southern Indiana.
Enhanced scrubber technology on coal-fired boilers generates increased volumes of coal combustion byproducts. Participants will examine the site of a coal combustion byproducts management facility to be developed on abandoned mine lands. An exposed highwall strip pit will be the site for byproduct placement. Hydrogeological monitoring and characterization data for mined area spoils and unmined Paleozoic rocks will be reviewed in the field.
Cost: US$40; student and K-12 educators: US$25; includes transportation, handout, and lunch. Min.: 5; max.: 27.
6. Urbanization, Stream Restoration, and Soils: Streambank Restoration and Fragipan Soils in Western Kentucky.
Sat., 26 April.
This trip has been canceled.
7. Seismic ground failure features in the Wabash and Ohio River Valleys.
Sat.–Sun., 26–27 April.
This trip has been canceled.
8. Revisiting New Harmony in the footsteps of the Prince of Wied, Charles Lesueur, and other Early Naturalists.
Sat., April 26.
This trip has been canceled.
9. Aspects of Pennsylvanian Stratigraphy, Sedimentation, and Conodonts, Southwestern Indiana.
Cosponsored by the Pander Society.
Sat., April 26.
Carl B. Rexroad, Indiana Geological Survey; Penny Meighen, Marshall Miller & Assoc.; John Nelson, Illinois State Geological Survey.
In order to gain an understanding of the stratigraphic setting, sedimentation, and conodonts of the somewhat repetitive Pennsylvanian rock sequences in southwestern Indiana, this trip will visit two coal mines exposing thick sections that show several stratigraphic units. We will also visit outcrops representing greater spans of the Pennsylvanian, providing an opportunity to collect from eight or nine stratigraphic units.
Cost: US$38; includes transportation, lunch, and handout. Min.: 9; max.: 27. Hard hats (available on loan) and steel-toe boots will be required to enter mines.
10. The Illinois-Kentucky Fluorite District and the American Fluorite Museum, Garden of the Gods, and Hicks Dome in southeastern Illinois.
Sat., 26 April.
Brett Denny, Illinois State Geological Survey (ISGS); Zak Lasemi, ISGS; Joe Devera, ISGS; John Nelson, ISGS; Alan Goldstein, Falls of the Ohio State Park.
This trip will begin with an orientation between 8 and 8:30 a.m. in the Aztar Executive Conference Center parking lot. Participants will travel across the Illinois-Kentucky Fluorite District to explore various aspects of structural geology, mineralogy, igneous intrusions, and mining history. Stops will include a zinc-fluorite mine near Marion, Kentucky (to observe an exposed vein and collect samples) and the American Fluorite Museum in Rosiclare. We will drive across the Hicks Dome crypto-explosive structure and view the Garden of the Gods to observe its relation to the Eagle Valley syncline.
Cost: US$37; includes transportation, lunch, museum fee, and handout. Min.: 10; max.: 25.
11. Geoarchaeology and Geophysics at the Angel Mounds Site, Evansville, Indiana.
Sat., April 26.
G. William Monaghan, Glenn A. Black Laboratory of Archaeology, Indiana University, +1-812-856-1853; Tammie Gerke, University of Cincinnati.
The Angel Mounds Site is a middle Mississippian town occupied between ca. A.D. 1000 and A.D. 1400. It includes some of the largest intact Mississippian earthworks in the Midwest. Our oneday field trip will focus on the results of recent archaeological and geoarchaeological research at the Angel Mounds Site. We will discuss a recently completed magnetometer survey of the town that shows the distribution of palisade walls, houses, and other buildings and what these reveal concerning site structure and formation. We will also discuss the results of a geophysical survey and solid-earth coring of Mound A, the largest of the site's earthen mounds, and examine how such minimally invasive data can be used to create a 3-D virtual model of the mound. Finally, we will reopen a profile across a Mississippian house that was recently excavated, discuss the archaeology and geoarchaeology of this structure, and provide evidence of liquefaction or other earthquake-related deformation that appears to have disrupted the floor of this house.
Cost: $35; includes transportation, lunch, museum tour, snack, and handout. Min.: 10; max.: 25.
