Is located high above the western side of Genowlan Creek, 1.1km south, south east of Point Hatteras. This very narrow 50cm wide and 5m high slot extends for about 30m. Because of many chockstones, this slot also has a second storey passage that can be walked to the top of the slot, hence the name. Named by Brian Fox and Yuri Bolotin on a bushwalk of 2 August 2019.
