1881 Article Flood Rock Excavation Explosion Hell Gate New York Harbor Reef MAB1

This is an original 1881 two-page print article about the removal of Flood Rock at Hell Gate in New York Harbor. The method employed in these operations is very simple in principle, but the work is both costly and tedious. To aid in this necessary operation, the surface of the reef is first cleared off with the aid of ordinary dredging machines and the water jet apparatus, the latter serving to carry away the sand and smaller loose particle of rock, and the purpose is to shatter these and the roof in one grand explosion. This accomplished, the shattered fragments of rock are removed by dredging until the proper depth of channel is obtained. This method was being employed on an extensive scale in the removal of the above mentioned rock reef in New York harbor. Fig. 1 represents a view of Flood Rock as it appeared; Fig. 2 shows it as it appeared before operations for its removal were undertaken; Fig 3. is a vertical section, showing the horizontal galleries; Fig. 4 is a ground plan of the excavations; and Fig. 5 a vertical section through the reef, showing the position of the shaft and the galleries.
