Painted by Jasper Francis Cropsey (1823-1900). Cropsey's many paintings in his native New York are most often studies in color more than topography or dramatic of water and sky.
He tended to autumnal colors, even in this scene that must be late summer, judging by the foliage.
Long before this site came to be dominated by the Bridge it provided the citizenry with a vista of the Hudson heading out to see and all that lay beyond. But the near features come in for detailed treatment, in the foliage and beaches on Long Island. Note even the shadows beginning to reach over the artist's shoulder.
