Michael Keats records, " The arch shaped rock is an ironstone residual that has more perforations than actual support rock holding it together. There are three major support points and these are all fluted, decorated and fenestrated like no other rock I have seen before. The interior of the arch is large enough to crawl into, and through if you are so inclined." Located above the cliff line on the northern side of the headwaters of Capertee Creek, 1.4km north east of Mount Dawson. Named by Yuri Bolotin on a Bush Club walk, 28th October 2013.
