  of 
  a 
  diabase. 
  Quite 
  large 
  bits 
  of 
  magnetite 
  are 
  present, 
  and 
  

   though 
  no 
  thin 
  section 
  has 
  been 
  made, 
  apparently 
  hypersthene 
  

   is 
  one 
  of 
  the 
  components. 
  The 
  gabbro 
  shows 
  a 
  tendency 
  to 
  pass 
  

   into 
  amphibolites 
  along 
  the 
  margins. 
  

  

  Series 
  4. 
  No 
  paleozoics 
  occur 
  in 
  the 
  township 
  except 
  Potsdam 
  

   boulders, 
  which 
  may 
  be 
  occasionally 
  observed 
  in 
  the 
  drift. 
  

  

  Series

  No 
  trap 
  dikes 
  were 
  met. 
  

  

  Series 
  6. 
  Glacial 
  deposits 
  are 
  widespread 
  and 
  post-glacial 
  or 
  

   supposed 
  post-glacial 
  sands 
  are 
  frequent. 
  Chestertown 
  is 
  situ- 
  

   ated 
  in 
  a 
  broad 
  valley 
  with 
  abundant 
  drift. 
  Pottersville 
  is 
  

   partly 
  built 
  upon 
  a 
  terrace, 
  that 
  stands 
  about 
  40 
  feet 
  above 
  the 
  

   Schroon 
  river, 
  which 
  would 
  make 
  it 
  about 
  850 
  feet

  Topography. 
  Hague 
  is 
  the 
  northeastern 
  township 
  of 
  the 
  coun- 
  

   ty 
  and 
  on 
  the 
  east 
  lies 
  along 
  Lake 
  George 
  throughout 
  its 
  entire 
  

   extent. 
  It 
  is 
  quite 
  a 
  mountainous 
  area, 
  whose 
  highest 
  summits 
  

   exceed 
  2000 
  feet. 
  As 
  a 
  great 
  rampart 
  on 
  the 
  north 
  Stevens 
  moun- 
  

   tain 
  reaches 
  2153, 
  Third 
  Brother 
  1956 
  and 
  Trumbull 
  mountain 
  

   2220. 
  The 
  southeastern 
  portion 
  is 
  occupied 
  by 
  Catamount 
  moun- 
  

   tain 
  2304, 
  and 
  its 
  spurs. 
  The 
  valley 
  of 
  Fly 
  brook 
  divides 
  the 
  town 
  

   into 
  two 
  east 
  and 
  west 
  portions, 
  in 
  the 
  southern 
  two-thirds, 
  and 
  

   then 
  the 
  east 
  and 
  west 
  depression 
  marked 
  by 
  the 
  brooks 
  en- 
  

   tering 
  Lake 
  George 
  at 
  Hague, 
  and 
  Mill 
  brook 
  flowing, 
  west 
  into 
  

   Brant 
  lake, 
  cuts 
  off 
  the 
  northern 
  third. 
  Trout 
  brook, 
  which 
  

   crosses 
  the 
  northeastern 
  corner 
  and 
  enters 
  Lake 
  George 
  at 
  Ti- 
  

   conderoga 
  presents 
  some 
  striking 
  reversals 
  of 
  direction 
  in 
  its 
  

   upper 
  tributaries 
  and 
  leads 
  one 
  to 
  suspect 
  stream 
  piracy. 
  The 
  

   surface 
  of 
  Hague 
  rises 
  steeply 
  from 
  Lake 
  George 
  and 
  at 
  

   Rogers 
  Slide 
  in 
  the 
  extreme 
  northeast 
  and 
  at 
  Deer 
  Leap 
  on 
  the 
  

   southeast 
  precipitous 
  escarpments 
  front 
  the 
  lake. 
  

  

  Series 
  1. 
  The 
  gneisses 
  constitute 
  much 
  the 
  greater 
  part 
  of 
  

   the 
  township 
  and 
  they 
  embrace 
  several 
  varieties 
  of 
  rock. 
  There 
  

   is 
  a 
  granitic 
  type 
  that 
  may 
  be 
  quite 
  massive. 
  It 
  is 
  rich 
  in 
  quartz, 
  

   has 
  mostly 
  feldspar 
  for 
  the 
  remainder 
  and 
  comparatively 
  few 
  

   dark 
  silicates.

  character.
