Mystery Mountain Slot
Named by Michael Keats and Brian Fox on a bushwalk of 28 July 2014. Michael recorded, “Soon we felt a strong breeze and the canyon walls became very high, about 25 m high. There was a reason for this breeze as a few more steps took us to the edge of the cliff line and a yawning void down 300 m into the Wolgan Valley. We had stumbled across the much talked about non-negotiable slot that separates Mystery Mountain from Island Mountain”.
