Seeing the way the giant mound along Destination Pkwy has been going down AND additional truckloads of dirt have been rolling into the construction site, it's not too surprising!
I was struck by the height variation looking at Fyre Drill the other day, realizing the queue goes under a bridge and how the surrounding area is so much higher than the ride will be so people can look down on it:
Aerial photos really don't give the full picture of the grade changes. It looks very much like Celestial Park is quite a bit higher at each end than the middle, and the waterways are going to be significantly lower than the walkways. The views should be amazing!
