### New York City Geology and History

New York City's bedrock is about 100 million years old
The city's current topography was shaped by glacial recession 10,000 years ago
Glacial activity created features like erratic boulders in Central Park, kettle depressions in Brooklyn and Queens, and moraines
River systems in New York City, such as the Hudson, East, and Spuyten Duyvil, are estuaries of the Atlantic Ocean, formed by glacial erosion
The city's approximately 600 miles of shoreline experience continuous erosion and sediment deposition
Despite dredging, ship channels in New York Harbor are prone to silting, making them unsuitable for modern deep-sea vessels
The deep water anchorage south of Manhattan offers easy access to the Atlantic Ocean
Giovanni da Verrazzano was the first European to enter New York Harbor in 1524, naming it Santa Margarita
The area displays a rich mineral diversity, with over 90 species of precious stones and 170 minerals found within the region
The Verrazano-Narrows Bridge, dedicated in 1964, commemorates Verrazzano's expedition
New York City's port played a significant role in American commerce, becoming the country's dominant trade center by the mid-1800s
New York was the busiest port in the world from the early 1900s until the 1950s
During the 1960s, containerization, outdated piers, and rising labor costs led to a shift in cargo operations to the New Jersey side of the Hudson River
