Has an overall length of over 80m, and there are two distinct sections, one narrow and one wide with a vertical wall at the end. Located on the northern side and above the headwaters of Canobla Creek, 1km south, south east of Point Anderson. Named by Yuri Bolotin on a Bush Club walk, 20th April 2017. Yuri recorded, “When during our previous trip, we had been standing above the slot and peering down into it, we were enthralled by the vision of long parallel walls, framing a rectangular space of almost perfect proportions; green, luxuriant tops of ferns and rainforest trees completed a beautiful, immaculate, somewhat utopian vision of a hidden paradise.”
