[2] A dam at the peninsula's east end creates a small pond, and its west shore edges the Neptune Basin inlet.

[3] The island was originally included in the "Commons" of the Town and, following the end of the American Revolution, it came under the ownership of Anthony Lispenard Bleecker.

[5] In 1837, Isaac Underhill and his wife Deborah built the "Neptune House" summer resort hotel.

In 1876, the Neptune House was also the terminal of Colonel DeLancey Kane's "Tally Ho" coach running daily between New Rochelle and the Brunswick Hotel in New York City.

[7] One section of the original hotel was left standing, and it was divided into four private houses that still remain at 1,2,3, and 4 Harbor Lane.
