We heard about Bear Clan Petroglyphs and the story is that they were secret and hard to find. We did some research and found them just west of the Redman Petroglyph. Turned out they were northwest on the cliff edge at the following coordinates.

To get there you leave St George on Warner Valley Road. You will need a high clearance vehicle ultimately as there is deep sand and some good rocks to negotiate. You follow this road about 3.25 miles when you come to a corral on the left. After the corral take the marked road on the right towards the cliff edge. The sand in the beginning is deep and the road then turns rocky. After turning off go about .8 miles and take the road to the right and cross a wash, stay on this road to the top of the ridge and follow to the end (right) to the rocks that have the petroglyphs on them.
