This is a big rock just beyond South Dinosaur Egg that sits right next to the creek. A few good sport lines can be found here.

Getting There 

Take Broadway and turn West on Table Mesa. Drive all the way to the end of this road to the NCAR parking lot. Now take the "NCAR Trail" along the nature walk along the rim of the hill. Look for a trail that cuts left and down the hill to some switchbacks. Follow this trail all the way to the water tower and continue left of the tower down to the Mesa Trail. Here, you will come to a junction with a Boulder Mountain Parks info/map board. Take the Mesa Trail to the South until you hit Bear Canyon. Follow this trail up the hill to the South, and then up the canyon on the South side of the creek. Look for this large rock just West of the Southern Dinosaur Egg.

The Fiend 5.13c 8a+ 30 X- 31 E7 7a  CO : Flatirons : ... : Stonehenge
The Fiend stems and contorts up the obvious, vibrantly colored, overhanging dihedral on the Stonehenge formation. Boulder past three bolts to a huge flake, place a red Camalot, and then funk your way past two more bolts, and increasingly difficult moves to the anchors. Unfortunately, an existing pebble was reinforced at the top of this route. Nevertheless, this is a very unique, and beautiful climb with a lot of value....[more]   Browse More Classics in CO

Thought Control and Auspice have had their hardware (bolts and anchors) upgraded, thanks to the Anchor Replacement Initiative. Also, many thanks to the Flatirons Climbing Council, OSMP, and the Access Fund for making the work possible.
