In the background we can see the 1st trench where the train will exit out of the station from the right. After the trench you can see the beginning of the lifthill. The big block of cement is going to be the maintenance barn.
Heres a picture of the 2nd trench where the coaster will drop down after the lifthill and go into the Stall-loop element.
The park has stated that they're nearly done with all the ground work and that the next couple of weeks will be focused on re-establishing parts of the forest that was needed to be cleared for construction.
