Hello Rita -- congratulations on your upcoming amphitheater. In Rocklin, CA, we opened, last April, a new amphitheater that was created out of an old rock quarry zone. This new area is called Quarry Park, and we quarried onsite the granite used in the amphitheater. Our amphitheater also includes a lake. Future phases of Quarry Park are scheduled to include rock climbing, a zip line and other amenities in a 7-story deep former granite quarry. We have already created a waterfall that cascades 70 feet down the rock walls. I have attached a photo of Quarry Park.We operate the activities and events in Quarry Park with City staff. Here is a link to the Quarry Park event website: http://www.rocklin.ca.us/events/concerts_at_quarry_park. I can place you in touch with our appropriate staff if you like. I have also attached a photo of Quarry Park.
