cavern was accidentally discovered by Miguel Manzano
Lobato. During the rainy season (Jul-Dec) he used water
to obtain hydraulic energy to move the machinery of his
alcohol distillery; however, the rest of the year the
level of the water was not enough. He decided to seek the
main vein to get water with enough pressure. He decided
to find water with enough pressure inside the mountain;
following the water flow he found the tunnel where the
water got out from the mountain, being this an obstacle
because the tunnel was very stretch. He widened it and
advanced very slowly, until he found a second obstacle: a
21-feet high waterfall. He climbed it and kept advancing.
On March 19th, 1919, he discovered the main chamber.
