Cueva Guacamaya, Auyán-tepui (Auyán-tepuy; Ayan Tepui), Bolívar, Venezuela
This cave was discovered in March 2009 on the Auyán-tepui by helicopter pilot Raul Arias. It represents one of the longest caves explored on this table mountain, the only one known today with a complete horizontal development, comparable with those of the Brewer Cave System, in the Chimantha Tepui (the world's largest sandstone cave).
This cave presents typical morphologies, developed along a thin layer of oxides, amorphous silica, and clay interposed between hard quartzitic massive banks (Mataui Formation). In the walls around this layer, a large variety of opal speleothems, of unusual dimensions and shapes, together with gypsum flowers and crusts, have been observed.
