[Journal entry for November 14, 2023; North Walkway of the George Washington Bridge]. I took the 10AM shuttle bus from the Lamont Campus to the main Columbia Campus on this beautifully clear day. After picking up additional passengers in Fort Lee, New Jersey, the bus became mired in traffic. After a half hour of creeping along Fort Lee streets, some of the Fort Lee passengers asked to be let off. I exited when they did and walked east on Main Street, and then north on Hudson Terrace to the start of the North Walkway of the George Washington Bridge. It has been closed for the past several years for maintenance and has only recently reopened. The first hundred yards or so are along a road-cut through the brown diabase rock of the Hudson Palisade. Asters and goldenrod growing from cracks in the rock are still blooming, in contrast to elsewhere in the area, where they have all gone to seed. Then the view opens up, with marvelous views of the Hudson River and the Palisade. The fence along the walkway is made of thin vertical metal bars separated by about six inches, so it was easy to peer between them to get an unobstructed view to the north. The tall cliffs of the Palisade are very dramatic. Trees below the Palisade cliffs are still in their Fall colors – mostly yellows, ambers and browns, with a touch of oranges and reds, too. I was about halfway across the bridge when the Lamont shuttle bus passed me. I didn’t mind being later than it, for the view was so terrific. After a while, the Manhattan shore became clearer as it drew near. Riverside Park, along the Manhattan shore, is in its Fall colors. The Cloisters and other buildings adjoining the park are brightly lit by the sun. The walkway ends with a long, looping ramp to Cabrini Blvd. And 180^th St, in Washington Heights. I walked to 181^st St. and then along it to St. Nicholas Ave., where I caught the #1 Local subway line down to Columbia University. About ninety minutes.
