[edit] Summary
USGS, Carlsbad Caverns National Park http://3dparks.wr.usgs.gov/carlsbad/html2/cc21.htm
Flowstone is a form of speleothem that forms where calcium-carbonate-rich water trickles down the walls of a cavern. Over time travertine accumulates in unusual drapery and ripple-shaped patterns, reflecting the constantly changing pattern of surface water flow and mineral accumulation.
