Hollick: Staten Island Bowlder Trail 9 



limonite bowlders, indicating that an extensive exposure of this 

 rock formerly occupied what is now the trough between the known 

 serpentine area to the southeast and the trap ridge to the north- 

 west in the vicinity of Linoleumville. And this trail, from the vi- 

 cinity of Crooke's crossing to the neighborhood of New Spring- 

 ville is sharply defined and narrow — only a quarter of a mile or 

 so in width — on either side of which only occasional scattered frag- 

 ments of the limonite may be found, and these but a short distance 

 frorii the margin. 



: At the present time there is no outcrop of the rock to be seen in 

 place, but formerly there was an exposure on Richmond Hill and 

 this may yet be located by means of the old abandoned and now 

 almost obliterated diggings or prospect holes, which were made 

 many years ago by parties who were interested in the commercial 

 development of the limonite deposits of the island.
