SATURDAY, 5 JUNE 2010 Rainwater Basins, Loess, and An Imaginary Younger Dryas Connection Saturday, June 5, 2010 1:09 PM In " YD Crater hunt (impactites?)" at http://six.pairlist.net/pipermail/meteorite-list/2010-June/065401.html, E.P. Grondine wrote: "It turns out the backtrack intercept was already mapped - the third image at http://cosmictusk.com. Sorry, but this image did not show on my computer. One hypothesied large fragment impact point in lower Michigan is shown. There should be another one not too far distant." There is one major problem with the Rainwater Basins, as they are called, being associated with a terminal Pleistocene impact. The oval basins that are exhibited by the modern land surface are palimpsest landforms created by a blanket of Middle, Late, and Holocene loesses and paleosols draped evenly over the original Rainwater Basins, which are developed in fluvial sediments. These sediments are at least, Illinoian in age, Marine Isotope Stage 6, approximately 130,000 to 196,000 BP old as a Late Illinoian Sangamon Soil is developed in them. it would be interesting to know the stratigraphic relationship of the Late Illinoian Sangamon Soil to these original basins as it would further constrain their age. Direct studies of these basins from cores and gully walls, reveal that the original basins are buried by undisturbed loess, which consists of an intact sequence, from bottom to top, of Middle Wisconsin Gilman Canyon Formation, Late Wisconsin Peoria Loess, Brady Soil, Holocene Bignell Loess, and other interbedded and associated paleosols (Zanner and Kuzila 2001, Zanner et al. 2007). The fact that the original basins are blanketed by loess of the Gilman Canyon Formation clearly demonstrates that the original Rainwater Basins are greater than 30,000 to 40,000 years TL and C14 (Johnson et al. 2008; Wiley 2009). It is quite obvious that the Rainwater Basins are far too old to be associated with any hypothetical Younger Dryas event. The presence of an intact and undisturbed blanket of Late Wisconsin Peoria Loess, Middle Wisconsin loess of the Gilman Canyon Formation, and associated paleosols covering the original Rainwater Basins makes any association between the them and the Younger Dryas a complete and utter physical impossibility as extraterrestrial impacts cannot create craters tens of thousands of years before they happen.

Basin Research Institute Bulletin. vol. 8. pp. 30-38. http://www.scribd.com/doc/32482964/Little-Creek-Structure-LaSalle-Parish-Louisiana The Little Creek Structure is an enigmatic polygonal structure that is located in La Salle Parish near the town of Little Creek, Louisiana. At the surface, this structure consist of an area of about 8 square kilometers of Miocene and other sediments that have been downfaulted by about two thousand feet within a 3.5 to 4.0 km in diameter ring fault system. The Miocene strata are surrounded by older Oligocene and Eocene sediments. This structure has been explained by either 1. piracy of a preexisting piercement-type salt structure, 2. meteorite impact structure, 3. a deep-seated subsurface igneous diapirism, 4. or a combination of any of these and other hypotheses. The surface expression of this structure consist of a series of discontinuous circular ridges One geologist, whom I talked with about the origin of this feature suspects that the interior of this feature is still subsiding.

It was discovered as the result of regional geologic mapping that I and others have been conducting. >From the available evdience, I am comfortable proposing the hypothesis that it might be an impact crater. However, much work remains to be done before any definite conclusions can be made about its origin. The results of the work that has so far been done is summarized in an article on pages 3 to 5 of the the June 2003 issue of the "Louisiana Geological Survey News." It can be be downloaded on-line from: http://www.lgs.lsu.edu/old/june2003.pdf http://www.lgs.lsu.edu/newsletter.htm This is very much a "work in progress." For example, since the above article was published, in situ shocked quartz has been found samples from highly fractured Citronelle Fm. lying beneath the rim deposits. Unfortunately, it was not until the very, very end of January that I had my shocked quartz authenticated with detailed work using an universal stage. As a result, I missed the GSA and Lunar and Planetary Meeting Deadlines. As a result, I will be presenting my theories in a poster session at the "Gulf Coast Association of Geological Societies 53rd Annual Meeting, Oct.22-24th, 2003, in Baton Rouge, Louisiana. More information this meeting can be found at: http://www.brgs-la.org/gcags.htm Under Posters Session, Thursday October 23, 2003, my poster is listed in: http://www.brgs-la.org/tech_program.doc as: "P20 P. V. Heinrich: Geologic Significance of Fractured and Shocked Quartz Associated with a Rimmed Circular Depression in St. Helena Parish, Louisiana." In addition to the poster, a ten-page paper with lots of details has been accepted for publication, after minor revision, in the Transactions of the Gulf Coast Association of Geological Societies, vol. 53 (2003). This will be distributed at and after the meeting. I hope to be out digging for more shocked quartz next Thursday. Among other things, I am getting ready to collect medium and shallow depth seismic data entirely across of 2 km diameter of this feature, now called the "Brushy Creek feature," in either late August or September. Also, other geophysical work is planned for this fall when temperature and humidity fall below the "heatstroke" and dehydration range.

Heinrich, Louisiana Geological Survey, Louisiana State University, Baton Rouge, LA 70803 heinric at lsu.edu ABSTRACT In 1996, geologic mapping of the Amite 1:100,000 quadrangle revealed an anomalous circular depression, now called the "Brushy Creek feature" within southwestern St. Helena Parish, Louisiana. The Brushy Creek feature consists of a circular depression about two kilometers in diameter with a low and dissected rim. Petrographic study of sand from this feature revealed the presence of both highly fractured and shocked quartz, not found in adjacent outcrops of the Citronelle Formation. A review of the regional geology of the area found no evidence of tectonic processes, e.g., volcanism and salt diapirism, which could account for the development of this depression. In addition, the geomorphic setting of the Brushy Creek feature is incompatible with the development of siliciclastic karst that has created similar depressions, e.g., the Carolina Bays. At this time, the Brushy Creek feature is hypothesized to be a dissected late, possibly terminal, Pleistocene meteorite impact crater. "The Brushy Creek feature occurs as a noticeable circular "hole" within the ridge and ravine topography that characterizes the surface of the Citronelle Formation within southeast Louisiana. This feature is roughly circular with a relief of about 50 ft (15 m) and a diameter of about 1.2 miles (2.0 km) (Fig. 1). The rim of the Brushy Creek feature exhibits a slight polygonal shape. The head-waters of Brushy Creek have breached the southeast rim of the feature and the northern rim is almost breached by a ravine tributary of Chandler Branch. The center of this feature lies at about 3405760N, 717870E, Zone 15, and 7 miles (11 km) southwest of Greensburg within St. Helena Parish, Louisiana."
