Is located below the main cliff face on the 900m contour on the western escarpment of the Wolgan Valley, 1.9km near due west of Cape Horn. Recent in terms of geology, a section of the cliff line has fallen away creating a huge opening and several tiered overhangs. Across the opening it is 30m+; the same from drip line to the back wall. It is an overpowering 50m high. The floor slopes at 45 degrees. The opening faces east. Vegetation is almost absent except for a white floweringEpacris crassifolia, seen and photographed high on northern back wall. Named on a Bush Club walk 11th June 2016 after Bill Lawler whose property is immediately below and bordered by the Wolgan State Forest.
