This is an artificial boulder that was created to cover up part of a cell tower. It seems to be made with Styrofoam and some sort of plaster coating. Climb at your own risk because this is a company owned structure and is probably not intended to be a boulder that people climb. However, there are some fantastic routes and plenty of FAs to be had.

Search this on Google maps 4651 Stratton Dr, Holladay, UT 84117. Its on the east side of the road. You cant miss it.
