This winter, with New York City’s Hudson and East Rivers particularly frozen (and sometimes trapping the ferries), New Yorkers are getting a first-hand glimpse at, well, nature. In-the-know New Yorkers like to point out that the East River is not actually a river, but is an estuary, meaning that waters come in from multiple sources, including salt water from the sea. On February 17th, the East River Ferry published an explanation, sharing how the tidal patterns cause unpredictable ice flows writing, “the tide changes multiple times per day, enabling ice to enter from different major bodies of water, making it nearly impossible to predict what it’s going to do, or where it’s going to be.” But what about the Hudson River?
