Conference proceedings 2004 are the vivid cave paintings from southern France and northern Spain, which are in some cases more than 30,000 years old (Chauvet, et ai, 1996). Yet, to call someone a "caveman" is to declare them primitive and ignorant. Caves, being cryptic and mysterious, occupied important roles in many cultures

,Cave Sediments and Denuded Caverns in the Laški Ravnik, Classical Karst of Slovenia,hat display apparently different histories of sedimentation, outwash and re-sedimentation, as well as possibly different sediment source areas. Additionally, such observations provide information about the spatial relationships of karst channels within a flow corridor.

Paleoclimate Information from Speleothems: The Present as a Guide to the Past,the environmental conditions at the time of deposition, (iv) they may trap surface-derived dust, pollen, and organic acids as the calcite layers are sequentially deposited and (v) they tend to behave as geochemically closed systems (see e.g. Schwarcz, 1986; Gascoyne, 1992).

Provenance of Suspended Sediment Discharged from a Karst Aquifer Determined by Clay Mineralogy, Springs is also a heavily used recreational spot, and it is the sole home of the Barton Springs Salamander (.), an endangered species that is extremely vulnerable to changes in water quality (Mahler and Lynch, 1999).

,Reading Virginia’s Paleoclimate from the Geochemistry and Sedimentology of Clastic Cave Sediments,from a nearby flood plain, a terrace soil, and a sinkhole pond also show mineralogical and geochemical changes. Goethite is abundant in the lower layers of the cave sequence, while the upper layers have mostly ferrihydrite and abundant kaolinite.

,: Last Interglacial Flood Deposits in the Caves of the West Indies,has been found, suggesting that the conditions which resulted in the formation of these flood deposits have been rare or absent in post-Sangamonian time. We interpret this pattern as indicative of an episode of severe climate (perhaps increased hurricane frequency or severity) that may have occurred during oxygen isotope substage 5e.

,Isotope Stage 11, the “super-Interglacial”, from a North Norwegian Speleothem,at coincides with the orbitally tuned SPECMAP date. The duration of isotope stage 11 interglacial is at least 27 to 45.5 kyrs (depending on the growth model used) supporting the longer of the published estimates of ∼30-40 kyrs (McManus et al., 1999).
