  The 
  northeast 
  fault 
  line 
  is 
  parallel 
  with 
  South 
  bay 
  and 
  the 
  

   escarpments 
  that 
  face 
  it, 
  and 
  with 
  many 
  others 
  in 
  the 
  paleo- 
  

   zoic 
  area.

  Topography. 
  Fort 
  Ann 
  is 
  a 
  very 
  large 
  township 
  that 
  lies 
  be- 
  

   tween 
  the 
  head 
  of 
  Lake 
  George 
  and 
  the 
  valleys 
  down 
  which 
  flow 
  

   the 
  inlets 
  of 
  Lake 
  Champlain. 
  Generally 
  speaking 
  it 
  consists 
  

   of 
  three 
  great 
  ridges 
  of 
  gneiss, 
  separated 
  by 
  intermediate 
  val- 
  

   leys, 
  and 
  it 
  has 
  an 
  additional 
  projection 
  to 
  the 
  southeast 
  that- 
  

   runs 
  out 
  into 
  the 
  paleozoic 
  area. 
  The 
  western 
  ridge 
  fronts 
  on 
  

   Lake 
  George 
  for 
  six 
  or 
  seven 
  miles 
  and 
  is 
  the 
  southern 
  prolonga- 
  

   tion 
  of 
  the 
  one 
  described 
  under 
  Dresden. 
  Its 
  altitude 
  gradually 
  

   diminishes 
  to 
  the 
  south 
  however, 
  for 
  while 
  Black 
  mountain 
  in 
  

   Dresden 
  is 
  2665, 
  Sleeping 
  Beauty 
  in 
  Fort 
  Ann 
  is 
  2349, 
  Buck 
  

   mountain 
  2334, 
  Pilot 
  Knob 
  2180, 
  and 
  finally 
  in 
  the 
  southwest 
  

   corner 
  the 
  hills 
  scarcely 
  top 
  500 
  feet. 
  This 
  great 
  ridge 
  is 
  some- 
  

   what 
  bolder 
  toward 
  Lake 
  George 
  than 
  to 
  the 
  southeast, 
  pre- 
  

   cisely 
  as 
  is 
  the 
  case 
  in 
  Dresden. 
  

  

  The 
  inlet 
  to 
  South 
  bay 
  forks 
  about 
  a 
  mile 
  above 
  the 
  bay 
  into 
  

   two 
  brooks. 
  Mount 
  Hope 
  brook 
  comes 
  in 
  from 
  the 
  southwest 
  

   in 
  a 
  deep 
  valley, 
  at 
  whose 
  highest 
  point 
  is 
  Lakes 
  pond, 
  at 
  859 
  

   feet 
  A. 
  T. 
  On 
  the 
  other 
  fork 
  which 
  comes 
  in 
  from 
  the 
  south 
  the 
  

   divide 
  is 
  not 
  over 
  300 
  feet 
  and 
  is 
  a 
  moraine, 
  as 
  was 
  first 
  stated 
  

   by 
  G. 
  F. 
  Wright.® 
  On 
  the 
  other 
  side 
  of 
  the 
  moraine 
  the 
  drain- 
  

   age 
  runs 
  to. 
  the 
  south 
  into 
  Halfway 
  creek. 
  

  

  The 
  southerly 
  flowing 
  streams 
  in 
  both 
  these 
  valleys 
  just 
  re- 
  

   ferred 
  to, 
  turn 
  a 
  sharp 
  corner 
  and 
  come 
  back 
  in 
  a 
  direction 
  

   north 
  of 
  east 
  through 
  Halfway 
  creek 
  into 
  Wood 
  creek 
  and 
  so 
  

   into 
  Lake 
  Champlain 
  at 
  Whitehall. 
  All 
  the 
  relations 
  lead 
  to 
  

   the 
  inference 
  that 
  there 
  has 
  been 
  a 
  reversal 
  of 
  the 
  drainage 
  and 
  

   that 
  the 
  discharge 
  formerly 
  went 
  southward 
  into 
  the 
  Hudson, 
  

   possibly 
  through 
  the 
  channel 
  detected 
  by 
  Prof. 
  Wright 
  6 
  at 
  South 
  

   Corinth. 
  The 
  subject 
  demands, 
  however, 
  more 
  detailed 
  study 
  

   for 
  its 
  elucidation 
  than 
  anyone 
  has 
  yet 
  given 
  it.
