Yesterday we bottomed the cave Tachycardia (JF270) in the Florentine valley, Tasmania. The surveyed depth being 375.2m, just bettering Niggly at 374.8m. The final pitch in the cave, Bermuda Triangle, was measured at 170m placing it as the second biggest in Australia after the Black Supergiant in Niggly at 190m. A full report will be published in the Speleo Spiel.
