Well, we thought we were on a hot trail, especially since no one here seemed to have mentioned it...I guess there was a reason for that!

We took Image 12, and matched it to Verse 5.
Image 12 is obviously New York City. We thought it may be some place around Grand Central Terminal. Although there is no park, we thought maybe there might be something in that vicinity where someone could dig. We went, and looked around, and although it seems very improbable, we can't seem to cross it off our list. Here is why:
Lane
Two twenty two
You'll see an arc of lights
The tracks in the main terminal go all the way up to 117. We thought it may refer to track 22.
Right before entering, there is an archway with lights hanging from it (arc of lights). Also, this archway leads to two tracks, one of which is 22.
Weight and roots extended
Weight of the trains; roots = train tracks
Granite walls
Wind swept halls
The walls in the main terminal are either marble or granite. The floors, if you were to take pictures and enlarge it, look like the pink bubbles in the upper left; the base moulding on the walls were like the blue bubbles in the upper right. The walls were of the same cream color as what is behind the tail of the bird.
Citadel in the night
Citadel has the obvious connotation; however, the definition is "A fortress in a commanding position in or near a city; a stronghold." Although the terminal is not a fortress, it is one of the largest railways of its kind in the northeast--we thought maybe there is a chance that it wasn't literal.
Also in the main terminal, the ceiling is the same blue behind the bird's face, with a celestial painting.
A wingless bird ascended
Born of ancient dreams of flight
The MetLife Building, which is attached to the terminal, used to be the Pan Am building.
Beneath the only standing member
There is a statue with a clock (although it looks nothing like the clock in the picture, other than the roman numerals) above the main entrance. Surrounding the clock are three statues of Hercules, Mercury, and another person. Hercules, in the center, is the only one standing. The interesting thing, however, was that there was another statute below this, that is not shown in any of the photos we came across on the Internet. It is of Commodore Vanderbilt, who was the shipping tycoon (ergo ocean). There is, of course, Vanderbilt Avenue right there. Then we came across the Grand Central Terminal police across the street on Vanderbilt Avenue. Perhaps this was the "citadel."
Of a forest
Although there are no forests in that area, we thought maybe it meant Park Avenue.
All the windows are similarly shaped as the "windows" in the upper part of the picture. Also, as you stand with your back to track 22, there is an abundance of daylight coming through, which could have been the arc of light, too.
Well, we are green, but we are trying. Looking into other possibilities now.
