I would classify the natural harbor and port around which the city was founded as a tremendous natural resource. The location allowed for the immediate establishment of a thriving business community based on trade with powers from around the world since there was easy access for seagoing vessels. The ports are protected from tremendous weather surges of water by the many islands that make up part of New York City, but the islands do not prevent the access of large ships. Because the Hudson River flows into the port, New York City also benefitted from trade to and from the interior of the new colonial area. As a natural feature that people have been able to use for great benefit, the New York City location is a great natural resource.
