  YORK 
  STATE 
  MUSEUM 
  

  

  is 
  a 
  tremendous 
  lateral 
  moraine 
  terrace 
  banked 
  up 
  against 
  the 
  

   mountain 
  front 
  along 
  the 
  west 
  side 
  of 
  the 
  Kayaderosseras 
  valley 
  

   and 
  a 
  smaller 
  but 
  similar 
  one 
  along 
  the 
  Mt 
  McGregor 
  front. 
  These 
  

   would 
  seem 
  to 
  have 
  been 
  deposited 
  along 
  the 
  sides 
  of 
  the 
  ice 
  lobes 
  

   which 
  occupied 
  these 
  valleys 
  during 
  the 
  retreat 
  of 
  the 
  last 
  ice 
  

   from 
  the 
  region. 
  They 
  are 
  overspread 
  with 
  sand 
  in 
  varying 
  

   amount, 
  deposited 
  from 
  streams 
  supplied 
  by 
  the 
  melting 
  ice, 
  which 
  

   flowed 
  along 
  the 
  margins 
  of 
  the 
  ice 
  lobes 
  between 
  the 
  ice 
  and 
  the 
  

   valley 
  wall. 
  

  

  DRUMLINS 
  

  

  These 
  are 
  oval-shaped 
  hills 
  of 
  drift, 
  chiefly 
  till, 
  supposedly 
  

   formed 
  underneath 
  a 
  glacier 
  near 
  its 
  end. 
  There 
  is 
  a 
  group 
  of 
  

   ten 
  or 
  a 
  dozen 
  such 
  hills 
  in 
  the 
  Kayaderosseras 
  valley, 
  grouped 
  in 
  

   a 
  rude 
  triangle 
  whose 
  apex 
  is 
  the 
  large 
  drumlin 
  just 
  south 
  of 
  

   Kings, 
  on 
  the 
  Adirondack 
  branch 
  of 
  the 
  Delaware 
  & 
  Hudson 
  

   Railroad, 
  and 
  whose 
  base 
  extends 
  across 
  southern 
  Greenfield 
  

   township 
  into 
  northwest 
  Milton. 
  Shaped 
  by 
  the 
  ice, 
  the 
  longer 
  

   axes 
  of 
  such 
  hills 
  are 
  supposed 
  to 
  trend 
  with 
  the 
  direction 
  of 
  ice 
  

   movement. 
  In 
  this 
  group 
  the 
  trend 
  varies 
  from 
  north-south 
  to 
  

   south 
  2o° 
  west. 
  They 
  show 
  prominently 
  on 
  the 
  topographic 
  map. 
  

  

  A 
  group 
  of 
  hills 
  of 
  similar 
  appearance, 
  east 
  of 
  Saratoga 
  lake, 
  

   Schuylerville 
  quadrangle, 
  are 
  rock 
  hills 
  and 
  not 
  drumlins 
  at 
  all. 
  

   Harder 
  bands 
  in 
  the 
  tipped 
  shales, 
  either 
  chert 
  or 
  sandstone, 
  are 
  

   responsible 
  for 
  these 
  hills. 
  

  

  TERRACES 
  

  

  There 
  are 
  several 
  broad 
  terraces 
  of 
  sand 
  and 
  gravel 
  within 
  

   the 
  mapped 
  limits, 
  chiefly 
  the 
  delta 
  deposits 
  of 
  streams 
  formed 
  

   during 
  the 
  ice 
  retreat 
  from 
  the 
  region. 
  Batten 
  kill 
  built 
  a 
  great 
  

   delta 
  in 
  the 
  higher 
  water 
  levels 
  of 
  the 
  time, 
  forming 
  a 
  great 
  ter- 
  

   race 
  east 
  of 
  the 
  Hudson, 
  banked 
  up 
  against 
  the 
  base 
  of 
  the 
  hills, 
  

   from 
  Bald 
  mountain 
  southward, 
  the 
  larger 
  part 
  of 
  it 
  being 
  south 
  

   of 
  the 
  present 
  position 
  of 
  the 
  stream. 
  

  

  Running 
  southwest 
  from 
  Gansevoort 
  through 
  Wilton 
  is 
  a 
  tre- 
  

   mendous 
  sand 
  terrace, 
  which 
  continues 
  on 
  into 
  confluence 
  with 
  

   the 
  similar 
  terraCe 
  to 
  the 
  east 
  and 
  south 
  of 
  Saratoga 
  Springs. 
  The 
  

   summit 
  levels 
  of 
  this 
  terrace 
  are 
  quite 
  like 
  those 
  of 
  the 
  Batten 
  kill 
  

   delta. 
  Southwest 
  of 
  Saratoga 
  Springs, 
  in 
  Milton 
  township, 
  is 
  

   another 
  great 
  sand 
  terrace, 
  at 
  a 
  somewhat 
  higher 
  level 
  than 
  the 
  

   other 
  two. 
  In 
  the 
  valley 
  south 
  of 
  Corinth, 
  hemmed 
  in 
  between 
  

   the 
  higher 
  grounds 
  on 
  each 
  side, 
  is 
  a 
  smaller 
  sand 
  delta, 
  at 
  a 
  much 
  

   higher 
  level.
