Is within the feature known as Mothers Arms on the eastern side of Genowlan Mountain, 1.2km south of Genowlan Point. This ‘room’ is accessed via beautiful dry overhang, 50m long and 3-4m high, with a flat floor covered with white powdery sand, which in turn leads to the bottom of a giant slot. This slot is likened to a room which continues for about 40m and terminates at a wall of ferns, pierced by a very narrow slot on the left hand side. Named by Yuri Bolotin and Brian Fox on a Bush Club walk on 22 December 2017 as the room is located next to Fantasia Traverse.
