This photo shows windows in the mansard section very similar to those at the top of the wood tower, which leads me to believe they were both added to the original structure at the same time. The 'stone' in the descriptions was really brick. This is consistent with the existing buildings in downtown and riverside Poughkeepsie, as there was a large supply of clay to make bricks. At least two brick factories are cited in the deeds related to Marist College land.

There was an addition of only one story at the foreground. This shows rough fieldstone. It may have been an addition during the Winslow era.

Winslow was intrigued with Victorian wood structures. Rather than demolish the Crosby house, he surrounded it with a wooden facade. A large chunk of the facade is visible in the lower center of this photo.

photos by Donald McTernan, who worked for the National Park Service. When he discovered the mansion was to be demolished, he rushed down to take photos. He donated copies of his photos to the Marist College Archives in February 2013.
