  GENERAL 
  TOPOGRAPHY 
  AND 
  GEOLOGY 
  

   As 
  compared 
  with 
  the 
  general 
  Adirondack 
  area, 
  the 
  North 
  Creek 
  

   quadrangle 
  presents 
  a 
  rather 
  unique 
  assemblage 
  of 
  topographic 
  

   forms. 
  Long, 
  prominent 
  mountain 
  ridges, 
  usually 
  with 
  northeast- 
  

   southwest 
  trend, 
  which 
  are 
  so 
  common 
  in 
  the 
  eastern 
  Adirondacks, 
  

   are 
  practically 
  absent 
  from 
  the 
  quadrangle, 
  and 
  instead 
  the 
  domi- 
  

   nant 
  topography 
  form 
  is 
  the 
  separate, 
  rounded 
  mountain 
  mass 
  or 
  

   dome 
  which 
  stands 
  out 
  conspicuously 
  above 
  the 
  surrounding 
  

   country. 
  Such 
  domes, 
  which 
  are 
  numerous 
  and 
  widespread 
  

   especially 
  in 
  the 
  southern 
  two-thirds 
  of 
  the 
  region, 
  are 
  commonly 
  

   from 
  500 
  to 
  800 
  feet 
  high. 
  The 
  highest 
  and 
  largest 
  of 
  these 
  domes 
  

   is 
  Crane 
  mountain 
  which 
  rises 
  2000 
  feet 
  above 
  the 
  immediately 
  

   surrounding 
  country. 
  Among 
  the 
  other 
  more 
  notable 
  examples 
  are 
  

   Hackensack, 
  1 
  Moon, 
  Potter, 
  No. 
  9, 
  Little, 
  Huckleberry, 
  Kelm, 
  

   Chase, 
  Prospect, 
  Mill, 
  and 
  Stockton 
  mountains. 
  These 
  domes 
  always 
  

   form 
  striking 
  features 
  of 
  the 
  landscape. 
  Ridges 
  do 
  occur 
  but 
  they 
  

   are 
  seldom 
  more 
  than 
  two 
  or 
  three 
  miles 
  long 
  and 
  do 
  not 
  assume 
  

   their 
  usual 
  importance 
  in 
  Adirondack 
  topography. 
  This 
  peculiar 
  

   North 
  Creek 
  topography 
  has 
  largely 
  been 
  produced 
  by 
  a 
  very 
  irreg- 
  

   ular 
  system 
  of 
  numerous 
  faults 
  in 
  combination 
  with 
  a 
  rather 
  wide- 
  

   spread 
  though 
  " 
  patchy 
  " 
  distribution 
  of 
  comparatively 
  weak 
  Gren- 
  

   ville 
  strata. 
  In 
  the 
  succeeding 
  pages 
  these 
  matters 
  are 
  described 
  in 
  

   detail. 
  The 
  maximum 
  range 
  in 
  elevation 
  is 
  from 
  about 
  640 
  feet, 
  

   where 
  the 
  Hudson 
  river 
  leaves 
  the 
  quadrangle, 
  to 
  3254 
  feet 
  at 
  the 
  

   summit 
  of 
  Crane 
  mountain. 
  Many 
  of 
  the 
  mountain 
  tops 
  show 
  

   altitudes 
  ranging 
  from 
  1200 
  to 
  2000 
  feet. 
  

  

  The 
  Hudson 
  river, 
  which 
  is 
  the 
  largest 
  stream 
  in 
  the 
  south- 
  

   eastern 
  Adirondacks, 
  passes 
  through 
  the 
  midst 
  of 
  the 
  quadrangle 
  

   from 
  the 
  northwest 
  to 
  the 
  southeast. 
  The 
  Schroon 
  river, 
  which 
  is 
  

   one 
  of 
  the 
  chief 
  tributaries 
  of 
  the 
  upper 
  Hudson, 
  cuts 
  across 
  the 
  

   northeastern 
  portion 
  of 
  the 
  area 
  and 
  thence 
  along 
  the 
  western 
  side 
  

   of 
  the 
  adjoining 
  Bolton 
  sheet 
  to 
  reenter 
  the 
  North 
  Creek 
  sheet 
  

   at 
  the 
  extreme 
  southeastern 
  corner 
  near 
  Warrensburg. 
  It 
  is 
  worthy 
  

   of 
  note 
  that 
  the 
  Schroon 
  river, 
  in 
  the 
  northern 
  portion 
  of 
  the 
  area, 
  

   flows 
  at 
  a 
  level 
  200 
  feet 
  below 
  that 
  of 
  the 
  Hudson 
  to 
  which 
  it 
  is 
  

   tributary. 
  All 
  the 
  drainage 
  of 
  the 
  quadrangle 
  passes 
  into 
  the 
  

   Hudson, 
  though 
  that 
  of 
  fully 
  two-thirds 
  of 
  the 
  region 
  does 
  so 
  by 
  

   first 
  entering 
  the 
  Schroon 
  river. 
  Within 
  the 
  map 
  limits, 
  scarcely 
  a 
  

   stream 
  of 
  any 
  consequence 
  enters 
  the 
  Hudson 
  from 
  the 
  east, 
  while 
  

   several 
  streams 
  of 
  considerable 
  size, 
  such 
  as 
  Patterson 
  brook, 
  Glen 
  

   brook, 
  and 
  Mill 
  creek, 
  enter 
  it 
  from 
  the 
  west.
