Is a most impressive buttress. When viewed from the Newnes side whilst driving the Wolgan Valley Road this rock juts out and dominates the cliff line. Located 900m south east of Collett Gap. Named by Yuri Bolotin on a Bush Club Walk 15th August 2016.
Local resident of Wolgan Valley, David Stafford records, “What you call Wolgan Rock we have always called The Sphinx due to its Sphinx like profile when viewed in certain light from the west (ie from our house).”
