Did you know?

That Rinnenkarren is (german.) solution grooves that form where runoff water is collected in streams. if the whole surface is moistened, the amount of water increases downwards with the result that the grooves are widened and deepened at the bottom. this distinguishes them from other similar forms. when the slope is slight they are coiled, but become straighter with increasing inclination. they are sometimes interpreted to be subcutaneous forms that develop below soil cover, but this is believed to be a rare occurrence. they are found in all climates. in arid zones, they exist as relics of the past when the climate was damper [3].?

Speleothems and paleoglaciers
Abstract:
Ice and speleothems are widely regarded as mutually exclusive as the presence of liquid water is a fundamental prerequisite for speleothem deposition. Here we show that speleothems may form in caves overlain by a glacier, as long as the temperature in the cave is above freezing and the conduits are not completely flooded by melt water. Carbonate dissolution is accomplished via sulfide oxidation and the resultant speleothems show high [delta]13C values approaching and locally exceeding those of the parent host rock (lack of soil-derived biogenic C). The [delta]18O values reflect the isotopic composition of the melt water percolating into the karst fissure network and carry an atmospheric (temperature) signal, which is distinctly lower than those of speleothems formed during periods when soil and vegetation were present above the cave. These `subglacial' speleothems provide a means of identifying and dating the former presence of warm-based paleoglaciers and allow us to place some constraints on paleotemperature changes
