Summary
[edit]DescriptionSolution pockets & pendants (Joppa Member, Ste. Genevieve Limestone, Middle Mississippian; Crystal Onyx Cave, near Cave City, Kentucky, USA) (23552026169).jpg |
Mississippian limestone in a Tertiary-Quarternary cave in Kentucky, USA. Crystal Onyx Cave is a relatively small, speleothem-rich cave on the eastern flank of Prewitts Knob, southwest of the town of Cave City, Kentucky, USA. The walls of the cave are limestones and dolostones of the Ste. Genevieve Limestone (upper Middle Mississippian). Crystal Onyx Cave was discovered in 1960 as a sinkhole. The name of the cave refers to the whitish-colored travertine (composed of calcite). Fifty-three Indian bones dating to about 680 B.C. were found wrapped up at the bottom of the main shaft of this cave. The photos in this album were taken in boreal summer 2008. The cave closed in 2008 or 2009 when a cell phone company (Bluegrass) bought the entire hill of Prewitts Knob to prevent competition from other cell phone companies. The hill now has cell phone towers. Locality: Prewitts Knob, ~2 air miles southwest of Cave City, northwestern Barren County, southwest-central Kentucky, USA (37° 06' 36.27" North latitude, 85° 58' 26.12" West longitude) |
