1999 Sequence Stratigraphy Field Trip
Concretions
Seneca Rocks
Caesar's Site
Rugose Coral
Kame Deposits




These are photos from a great outcrop of the Montebello Member of the Middle Devonian Mahantango Formation along Rt 322 north of Harrisburg, Pennsylvania. I took them on February 26, 1999, during the Wright State University Sequence Stratigraphy field trip run by Dr. Bill Slattery every other year. The photos are taken facing northeast, and stratigraphic up is to the left. The top photo shows Chris "Dickey" Buckman (left) and "Free" Mike Greer looking at the talus pile below a bunch of small faults in the outcrop. The middle one shows a channel to the right of the person (can't remember his name), and the bottom one is a close-up of sedimentary structures within the channel.


These photos show calcareous concretions in some shale along rt. 60, between Glasgow and Hugheston, Kanawha County, West Virginia. They were taken May 16, 1999. There are probably 10 concretions at this outcrop, but these photos show the same three from different angles. One amusing but unlikely theory of their origin was spraypainted on one of the concretions: "Dino-poop".
This is me at the top of Seneca Rocks, Pendleton County, West Virginia, on July 1, 1999. The rocks are the Silurian Tuscarora Formation (quartzite and conglomerate), which is nearly vertical there.






These are photos from an archaeological site that I worked on in July and August of 1999, for Indiana State University Archaeology Laboratory (ISUAL). The site is along the Ohio river in Indiana about 5 miles southwest of Jeffersonville, along rt. 111, in Harrison County. It is on a floodplain of the river below some bluffs capped by the Mississippian Borden Group, which contains high quality chert. The site was used by the Archaic Culture about 9000 years ago as a lithic production center. Now it is used by Caesar's as parking lots and hotels to support their riverboat casino. The top photo shows the Caesar's building from the northeast, with the bluffs to the right, and the "airplane hangar" shelter over one of the excavation areas (the one I worked in). The next photo shows a 2m x 2m test unit that I excavated. The next photo shows a close-up of the corner of the unit, showing the peds within the 9000 year old soil (scale is about 6 inches long). The bottom photo shows the method of extracting artifacts from the soil - a wet screen. One of my co-workers described the water coming out of the fire hose as "pure science". Click here for a fairly blurry photo (but the only one I have) of one of the many spectacular artifacts found at this site.
This photo shows a very large rugose coral ("horn coral") at the Falls of the Ohio, Jeffersonville, Indiana, which is across the Ohio River from Louisville, Kentucky. The Devonian Jeffersonville Limestone is a reef at this location. Large tabulate corals, bryozoans, brachiopods, and other fossils are abundant here, but they don't photograph all that well or I would have put more pictures on this page.


These are photos of sedimentary structures in a Pleistocene (Wisconsinan) unconsolidated kame deposit in Moraine, Ohio, taken September 28, 1999.
Comments of Dr. David Dominic: 'Indeed!'
