Washington, DC where I live, and New York City, where I am visiting, have something important in common. Both have beautiful urban oases designed by Frederick Law Olmsted.
The topography of Central Park was carved out by the glaciers that covered the area during the Ice Age. The Park has outcroppings all over the place.
The one in the picture on the right was a favorite of mine when I lived in the city. I worked at Rockefeller Plaza, and i would often bring my lunch and a book to this rock to get away from it all.
Then, there is the Wollman ice rink, a favorite movie and TV set for skating scenes.
At the southern end of Central Park, There is the beautiful reservoir that is home to a population of huge carp.
Central Park was planned to begin at 59th Street (now called Central Park South) when the city only went north as far as about 38th Street. The planners had a vision of a beautiful place where people could go to get away from the crowds and dirt of the densely populated urban neighborhoods. You can't help but wonder if they foresaw the huge buildings that circle today's Central Park.
