  Series 
  6. 
  Glacial 
  drift 
  is 
  widely 
  distributed 
  over 
  the 
  interior 
  

   valleys, 
  but 
  no 
  special 
  sign 
  or 
  color 
  is 
  used 
  for 
  it. 
  Along 
  Lake 
  

   Champlain, 
  the 
  Chainplain 
  clays 
  form 
  a 
  fringe 
  that 
  sets 
  up 
  into 
  

   the 
  depressions 
  and 
  that 
  sometimes 
  fronts 
  the 
  cliffs. 
  Two 
  sharply 
  

   marked 
  terraces 
  are 
  visible 
  in 
  the 
  clays, 
  one 
  about 
  40 
  feet 
  above 
  

   the 
  lake, 
  (140 
  A. 
  T.) 
  and 
  one 
  60 
  feet 
  (160 
  A. 
  T.). 
  Still 
  higher 
  shore- 
  

   lines 
  are 
  probably 
  present,** 
  but 
  we 
  made 
  no 
  special 
  attempt 
  to 
  

   trace 
  them. 
  No 
  fossils 
  were 
  noted 
  in 
  the 
  clays. 
  

  

  Glacial 
  striae 
  were 
  recorded 
  in 
  several 
  places. 
  In 
  each 
  in- 
  

   stance 
  the 
  direction 
  was 
  northeast 
  and 
  southwest. 
  

  

  Mines, 
  etc. 
  There 
  are 
  no 
  mines 
  or 
  other 
  economic 
  developments 
  

   in 
  the 
  town. 
  

  

  Faults. 
  There 
  has 
  been 
  considerable 
  post-Ordovician 
  faulting. 
  

   The 
  sections 
  A 
  A 
  and 
  BB 
  on 
  plate 
  1, 
  show 
  these 
  and 
  bring 
  out 
  

   clearly 
  the 
  faulted 
  contacts 
  of 
  the 
  paleozoics 
  on 
  both 
  the 
  old 
  

   crystallines 
  and 
  on 
  each 
  other. 
  The 
  faults 
  trend 
  in 
  a 
  north 
  or 
  

   northeast 
  direction 
  but 
  the 
  amount 
  of 
  the 
  throw 
  could 
  not 
  be 
  

   determined. 
  The 
  Potsdam 
  of 
  the 
  northern 
  area 
  reaches 
  an 
  alti- 
  

   tude 
  of 
  634 
  feet 
  A. 
  T., 
  and 
  the 
  Calciferous,

  of 
  Putnam 
  

   village 
  stands 
  about 
  as 
  high. 
  

  

  Dresden 
  

  

  Topography. 
  Dresden 
  presents 
  much 
  the 
  same 
  topography 
  as 
  

   Putnam. 
  The 
  high, 
  rocky 
  neck 
  between 
  Lake 
  Champlain 
  and 
  

   Lake 
  George 
  is 
  continued 
  to 
  the 
  south, 
  with 
  a 
  tendency 
  to 
  widen 
  

   somewhat. 
  The 
  greatest 
  altitudes, 
  as 
  before, 
  are 
  near 
  Lake 
  

   George. 
  Mt 
  Erebus 
  in 
  the 
  southwest 
  corner 
  of 
  Dresden, 
  reaches 
  

   2533 
  feet 
  and 
  Black 
  mountain 
  2665 
  feet, 
  but 
  there 
  is 
  no 
  longer 
  the 
  

   gradual 
  slope 
  to 
  Lake 
  Champlain. 
  On 
  the 
  contrary 
  a 
  steep 
  ram- 
  

   part 
  of 
  fairly 
  high 
  hills 
  fronts 
  the 
  latter. 
  There 
  are 
  several 
  east 
  

   and 
  west 
  passes, 
  of 
  which 
  the 
  one 
  running 
  west 
  from 
  Dresden 
  

   Center 
  is 
  the 
  most 
  notable. 
  The 
  valley 
  of 
  Pike 
  brook 
  is 
  a 
  marked 
  

   depression 
  with 
  a 
  bearing 
  west 
  of 
  north, 
  but 
  aside 
  from 
  it, 
  most 
  

   of 
  the 
  brooks 
  run 
  nearly 
  east 
  or 
  west 
  into 
  the 
  two 
  lakes.
