Boulders scattered along a steep hillside just off US Highway 6 in CCC. Maverick's Boulder is fairly easy to access, very nice rock, I believe it is gneiss....more info in one of the Colorado bouldering guides.
Heading west on US Highway 6 from Golden, park at mile marker 268. The boulders are across the street and up the hill. The Maverick's Boulder is pretty huge and obvious and takes only a few minutes to get to from the bottom.
I think it's also worth mentioning that many of the problems in this area are highballs with questionable landings, make sure you bring plenty of pads and spotters.
I have also personally seen several rattlesnakes in this gully during the warm months, and even the fresh kill of bighorns (mountain lions about), so just be prepared and know how to handle that sort of situation should you come upon it....
