Also known as Joachim Creek
Where: Jefferson County, Missouri (38.3° N, 90.4° W: paleocoordinates 38.3° N, 90.4° W)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: Late/Upper Pleistocene (0.1 - 0.0 Ma)
• considered to be "late Pleistocene" based on faunal composition
•the fossiliferous "clay horizon showed no sequence of faunas whatsoever" and appears to be about two feet thick in an illustrated section where it is overlain by "gravel in clay" and above that "thick layers of travertine" that sealed the fissure
• bed-level stratigraphic resolution
Environment/lithology: fissure fill; claystone
Size class: macrofossils
Preservation: midden
Collected by C. Jenni, E. C. Olson, W. Read in 1939
Collection methods: quarrying,
• University of Chicago collection
•the fissure was "excavated" by Olson and Read
