Prospect Park is a 585-acre urban oasis located in the heart of Brooklyn, New York City’s most populous borough. The masterpiece of famed landscape architects Frederick Law Olmsted and Calvert Vaux, who also designed Central Park, Prospect Park features the 90-acre Long Meadow, the 60-acre Lake and Brooklyn’s only forest. The nation’s first urban Audubon Center, the Prospect Park Zoo, and the Celebrate Brooklyn! Performing Arts Festival are just a few of the cultural attractions that make their home here at the Park.
At first glance it appears that the 19th-century paneling of Meadowport Arch's long, cedar- sheathed tunnel is, by some miracle, almost intact, although damaged. But a stone plaque in the ground makes it clear: This marvelous, inspiring work, a 100-foot-long Grand Central Terminal waiting room of polished wood was lovingly recreated in 1988, barely a generation ago.
You should visit the arch and walk through its coolness to reach the great lawn but the cache is not inside the arch. Depending on your approach to the GZ some bushwacking might be needed however some seekers, with a jogger's approach, can basically walk right up to it.
The cache is not touching anything man made.
