1900 Map of Oyster Bay

Inland, the development of the Long Island Railroad network, including the Oyster Bay Branch, catalyzed the growth of established villages like Oyster Bay, Hicksville, and Mamaroneck. The map captures a period when large estates were beginning to characterize areas such as Old Westbury and Wheatley, while working landings like Glen Cove Landing remained vital for local transport. Significant elevations like Harbor Hill provide topographical contrast to the salt marshes of Mill Neck.
