East Bay, you were correct in taking the trail to the left where it branches and going down to the stream. Where this trail meets the stream bed go straight across the stream at this point and you will find a trail on the other side. It is easy to spot once your on the other side. Follow this trail up stream for a little more than a half mile and it will drop down to a large flat area on the north hand side of the stream. When you first reach this wide, relatively flat area there will be a couple of very big cottonwood trees. Theres is a dry wash that comes out of a canyon and goes right next to these trees. follow this wash up hill maybe 75 yards or so and where this wash enters into the canyon there are granite boulders in this wash. about 4 of the grinding holes are in or next to the wash and are clear to see. The others are scattered very close by on the south side of this wash. This spot is maybe 150 yards north of the creek. Just before you get to the cottonwoods you will pass a large, metal sign next to the trail. I can't remember exactly what it says but you can't miss it. Once you see this sign the cottonwoods are in front of you. Youv'e probably seen the picture of one of these grinding holes at the link at the bottom " more hotsprings pictures " under wizard. Its interesting to think about the indians living at that site many years ago. Hope you have better luck next time.
