CAVE DESCRIPTION 2000a: Allegedly a mind-boggling tectonical slip rift [note 4] 6 m High by 1.5 m Wide (Boyes, P W 2000.02.22 Mss). CAVE DESCRIPTION 2000b: A tectonic [sic!] rift feature or enlarged bedding plane in sandstone (WILKINSON 2000: 48) estimated 1.5 m wide, 6 m high and together with the 2nd –>Dauki Rift Cave estimated 30 m long.
