Are two slots within the Koopartoo Mesa complex. Located 1.9km west of the Wolgan River and Zobels Gully junction. Named by Yuri Bolotin on a bushwalk 22 August 2017 who recorded,“two thin parallel slots, close to one another, about 130m and 80m long, both negotiable. You can take one to go up for incredible views from the top, and another one to come down. I will call them Ariadne Needles.”The name is in keeping with the mythology theme names related to the Minotaur, Ariadne Thread, etc.
