The picture below is the dawn view from a point near the posted co-ordinates. Anywhere along the road edge where you have a clear unobstructed view (and can see most of the photo) will be sufficient. Nearby is Prospect Park which has been known in the past as The Clear (hence the cache name). Charles Brasch authored a poem called "The Clear" and he is said to have enjoyed the view from this location. In the park you will find a memorial seat and plaque with this poem in full (unveiling was in Feb 2010). This is worth a look but is not relevant to the cache.
You will need to go to the posted co-ordinates at night (with photo) in order to complete this cache. It may take some time before the eureka moment. Take your SO and spend some time gazing at the view…ignore anything that is moveable.
At the next waypoint you will find the latitude and longitude for GZ in separate places at the waypoint. Use your cacher instinct (and imagination).
Hints:
Photo + waypoint: none, it is meant to be a challenge (you might end up with a couple of candidate locations, only one fits the bill).
GZ: getting hot when you've found the rope, accuracy 6m. Cache under base of trunk of tree that the blue rope is hung from. Temporarily 400ml snaplock after being muggled. Please reconceal well - evidence suggests this is a semi popular play area. Logs with spoilers will be deleted.
