The upper layers of the Breccia are overlain by layers of flowstone and other calcite deposits dubbed the "Crystalline Stalagmite", with the earliest layers of flowstone forming during MIS 11 ~400,000 years ago, though there was a major pulse of calcite deposition during MIS 9, around 300,000 years ago. The Breccia subsequently experienced some
