Terrible image below but you will get the idea, just browsing some photos and this seems to be the closest angle to the concept art we have to date, also the opening forming on the right seems to line up with the concept art showing what looks like a cave, just from this image I would presume we are only around half the height. The one steel highlighted on the real photo in the center would represent what I would presume to be the ledge created in the middle for the waterfall area. I tried photshopping these overlay-ed onto each other but it got too busy to really make out what was going on, so I end up going simple, ms paint style
. Not sure if the slide pieces that have been attached to the structure are related to the one shown sticking out from the right of the concept but there may be a good chance they are.
