The entrance, which used to have a green, wooden door, is in a small limestone face. The first chamber contains passage on the right which closes down. Excavations in the cave in 1962 have revealed remains dated to the Magdalenian VI Period, although some of the levels may be Azilian. González Morales Manuel et al, 2004, p65 quotes a date of 6360±120 BP for a "deposit overlying its terminal Magdalenian sequence.
Boulders shown to the northeast of the entrance on the 2004 survey may be concealing a passage shown on the 1986 version.
Ruiz Cobo Jesús and Muñoz Fernández Emilio et al, 2009 has a comprehensive summary of the deposits.
