From what I gathered from the rather limited response I received, the carvings have been removed from the wall that they once turned into a magical sea of delights, and are not on display, but are in the building. I then asked if they could be made available, but never received a reply; however, the implication in the earlier response was that they could be made available and I should talk to the park ranger on duty at the visitor center at the time.
