Is a tight, narrow and relatively deep, short, dry canyon on the southern side of the Wolgan River, 1.4km east of Wolgan Gap. Before and above the cliff line, the canyon ends in a rectangula rroom, some 10m x 40m, surrounded on all sides by soaring cliffs and, centrally disposed in this room, is a clump of 12 Brown Barrel Gums. Michael Keats on a Bush Club walk, 4th October 2013, named this feature The Covenant Room and the ravine, Holy Grail Ravine. Names chosen were in keeping with Indiana Jones movie themes for this area.
