Pudding Rock, 1883.

According to the NYPL description of this image...

A truly immense glacial boulder, rising 25 feet in the air, and being 30 feet in diameter. On one side was a natural fire-place, where the Indians used to enjoy their corn feasts and oyster banquets. Under its cool shade, the Huguenots rested on their long Sabbath Day journeys from New Rochelle down to the old French Protestant Church in lower New York. After serving as a natural landmark to early settlers and to travelers in stage coaches en route from New York to Boston, it has finally been blasted into countless fragments so as no longer to "obstruct the march of civilization."

Supposedly the local English farmers thought the massive rock looked like great big Christmas plum pudding, and so they named it the Pudding Rock.
