I think they read my post because the webcam is now fixed. Appears the pit they are digging for the base terminal is mostly done and they're preparing to set tower 3 (the first support tower). Towers 1 and 2 will be the initial hold downs out of the bottom terminal.
I also noticed that they cut down an area of trees behind there to make more space for skiers due to the gondola terminal taking up much of the width in that location. The terminal appears to be about the same place as the first tower on the double double is.
