Geology of Mammoth Cave, form where water is able to descend straight downward along fractures that cut across the layers. Below the water table, underground water follows the most efficient paths of flow, along the widest openings, to form tube-shaped passages. Former positions of the water table can be determined from th

Hydrology and Hydrogeology of Mammoth Cave,ves through the conduit system in response to storm flow. Chemical analysis of spring water, cave stream water, and cave drip water allows the calculation of dissolved carbonate (hardness), chemical saturation state, and concentration of dissolved CO.. Spring and shaft waters are undersaturated; dri

Subsurface Aquatic Ecology of Mammoth Cave,or flows rapidly through a sinkhole. Whether water moves slowly or rapidly through this unsaturated zone of partially water-filled channels it ultimately reaches the water table and flows out of springs along the Green River (Fig. .). When the Green River rises during floods, springs and base-level
