It is also applied to those brecciated and stalagmitic deposits on the floor of caves, which frequently contain osseous remains.
Of particular interest is the presence of patches or ledges of an old stalagmitic floor, three to four feet above the present floor.
Dr. Hovey has proved that the rate of stalagmitic growth in Wyandotte Cave, Indiana, is .0254 cm.
The traces of human occupation are pieces of charcoal, flints, moccasin tracks and a single skeleton embedded in stalagmite in one of the chasms, estimated, from the present rate of stalagmitic growth, to have lain where found for not more than five hundred years.
His careful estimate of the rate of stalagmitic growth showed that r000 years would have been needed to form the lip now covering the incision.
