Westchester Avenue, west side, between Hobart and Morris Park Avenues, showing the "Spy Oak," June 1926.

The exact location of this tree is unknown as it now longer stands. It was said to be the largest of its kind east of the Rocky Mountains and the last remaining vestige of the vast primeval forest that once covered this entire area. History tells us that during the American Revolution, a British spy, captured in this neighborhood, was summarily hanged from one of its branches, hence its name.
