  rocks 
  is 
  probably 
  due 
  to 
  a 
  cross 
  folding 
  that 
  combines 
  with 
  the 
  

   normal 
  fold, 
  a 
  frequent 
  cause 
  of 
  brachyanticlines. 
  

  

  A 
  nearly 
  continuous 
  line

  small 
  elliptic

  (mostly

  limestone 
  extends 
  in 
  southwest 
  direction 
  from 
  Stissing 
  mountain 
  

   toward 
  and 
  beyond 
  Newburgh. 
  In 
  the 
  close 
  neighborhood 
  of 
  

   Xewburgh 
  there 
  are 
  no 
  less 
  than 
  three 
  small 
  gneiss 
  and 
  one 
  Cam- 
  

   bric 
  limestone 
  inliers^ 
  [see

  and 
  a 
  series 
  of 
  small 
  inliers 
  

   of 
  gneisses 
  and 
  Cambric 
  rocks 
  extends 
  thence 
  along 
  the 
  north 
  side 
  

   of 
  the 
  Skunnemunk 
  mountains. 
  Ries 
  gives 
  four 
  sections 
  through 
  

   one 
  of 
  these 
  (Bull 
  hill) 
  which 
  clearly 
  show 
  its 
  composition 
  of 
  an 
  

   open, 
  normal 
  anticline 
  but 
  also 
  indicate 
  that 
  faulting 
  may, 
  to 
  

   some 
  extent, 
  have 
  influenced 
  the 
  production 
  of 
  some 
  of 
  these 
  inliers.
