Ahhh just noticed this comment post at the bottom of the page for the anvils,
will be following these steps:
This area isn't too hard to find, if you know where to look. The GPS coordinates were off by almost a mile, causing us to get lost and bushwack around for a few hours before finding it! I've moved the coordinates so they're right on top of the Alien Baby boulder now: 34 52' 20.0"N, 111 45' 13.9"W, or 34.872222, -111.753861.
The pullout on the left you want to park at is dirt and can maybe fit about 3-4 cars max. It's just prior to some therapy place on the right side of the road. Google Maps shows it at the intersection of 89A and Loma Casa Ln. Scramble down the slope (it's only about 20 ft high) and cross the creek wherever looks good, then look for cairns heading SSE. You should run into what looks like an old concrete path; the boulders are just E of that.
