We found it this time after a 2 mile trek over the Black Mountains due to the advent of GPS technology! It's not the easiest cave to find and almost impossible if you only have the instructions in the guide book to follow. Also the description in the guide book appears to be incomplete. We explored most of the 'old series' and dropped the second pitch to explore some of the new. Lots of places in the cave to still explore next time.
