However, it is important to stand out that under such sandstones may occur limestones from the Bambuí group, and the collapse of this subjacent limestone could have led to the collapse of the associated sandstones coverings, originating the cave.

Thus, its inner portion is quite preserved. However, it is worrying the advanced state of deforestation of the immediate epigean area surrounding the cave. The cave entrance is located in the middle portion of a narrow strip of vegetation (approximately 580 meters long by 37 meters wide) surrounded by areas of bare soil or with monocultures. Although one small border of this vegetated area is connected to an extensive preserved area, the cave is situated nearly 300 meters from this connection, being subject to changes resulting from external deforestation, which implies in alterations on the processes of input of organic resources from the external environments.</paragraph>
