  moraine 
  forms, 
  sometimes 
  toward 
  the 
  southern 
  edge 
  tending 
  toward 
  

   the 
  (Irumlin 
  form, 
  as 
  if 
  that 
  edge 
  of 
  the 
  moraine 
  had 
  been 
  over- 
  

   ridden. 
  No 
  doubt 
  some 
  of 
  the 
  smaller 
  present 
  hills 
  are 
  of 
  the 
  

   nature 
  of 
  dunes 
  as 
  there 
  are 
  localities 
  where 
  the 
  sand 
  is 
  still 
  exposed 
  

   to 
  the 
  free 
  action 
  of 
  the 
  winds. 
  A 
  considerable 
  part 
  of 
  the 
  city 
  of 
  

   Gloversville 
  is 
  situated 
  on 
  this 
  moraine, 
  and 
  the 
  more 
  direct 
  road 
  

   from 
  Gloversville 
  to 
  Broadalbin 
  is 
  about 
  in 
  the 
  center 
  of 
  the 
  

   moraine 
  and 
  traverses 
  a 
  region 
  which 
  has 
  many 
  of 
  the 
  characteris- 
  

   tics 
  of 
  a 
  desert. 
  This 
  grade 
  moraine 
  apparently 
  was 
  accumulated 
  

   between 
  the 
  two 
  lobes 
  already 
  described 
  where 
  the 
  edges 
  touched 
  

   or 
  approximated 
  each 
  other. 
  As 
  far 
  as 
  can 
  be 
  judged 
  from 
  limited 
  

   observations 
  and 
  from 
  the 
  appearance 
  of 
  topographic 
  maps, 
  the 
  

   moraine 
  belt 
  extends 
  from 
  Barkersville 
  northeastward 
  along 
  the 
  

   base 
  of 
  the 
  mountains 
  to 
  Corinth. 
  Its 
  western 
  extension 
  if 
  any, 
  

   has 
  not 
  yet 
  been 
  traced. 
  

  

  Recessional 
  moraines. 
  South 
  of 
  the 
  moraine 
  already 
  described, 
  

   in 
  the 
  field 
  of 
  the 
  Mohawk 
  glacier, 
  special 
  moraine 
  accumulations 
  

   are 
  almost 
  absent 
  excepting 
  heavy 
  deposits 
  of 
  till 
  in 
  the 
  Mohawk 
  

   valley 
  which 
  have 
  been 
  so 
  reshaped 
  as 
  largely 
  to 
  lose 
  their 
  char- 
  

   acter 
  as 
  moraines. 
  In 
  any 
  case 
  they 
  represent 
  dumping 
  and 
  

   filling 
  in 
  the 
  immediate 
  Mohawk 
  valley 
  and 
  the 
  work 
  of 
  localized 
  

   tongues. 
  The 
  region 
  south 
  of 
  the 
  river 
  to 
  the 
  limit 
  of 
  the 
  district 
  

   is 
  distinctly 
  free 
  of 
  anything 
  which 
  could 
  be 
  called 
  morainic. 
  On 
  

   the 
  eastern 
  edge 
  of 
  the 
  district 
  from 
  the 
  interlobate 
  moraine 
  south- 
  

   ward 
  to 
  the 
  Mohawk 
  river 
  a 
  number 
  of 
  small 
  morainic 
  areas 
  were 
  

   found, 
  generally 
  of 
  till. 
  It 
  is 
  evident 
  that 
  these 
  extend 
  over 
  in 
  some 
  

   measure 
  into 
  the 
  Saratoga 
  quadrangles 
  eastward, 
  and 
  further 
  study 
  

   may 
  develop 
  a 
  distinct 
  belt 
  of 
  such 
  moraine. 
  In 
  that 
  case 
  it 
  would 
  

   appear 
  to 
  mark 
  the 
  recession 
  of 
  the 
  glacier 
  out 
  of 
  the 
  Mohawk 
  valley 
  

   to 
  limit 
  the 
  western 
  edge 
  of 
  the 
  Hudson 
  valley 
  glacier 
  at 
  that 
  stage 
  

   of 
  recession. 
  This 
  would 
  be 
  in 
  harmony 
  with 
  Professor 
  Wood- 
  

   worth's 
  efforts 
  at 
  the 
  determination 
  of 
  the 
  existence 
  of 
  a 
  Hudson 
  

   valley 
  glacier 
  extending 
  down 
  toward 
  Schenectady 
  and 
  thus 
  pre- 
  

   venting 
  the 
  accumulation 
  of 
  the 
  sands 
  of 
  Lake 
  Albany 
  over 
  the 
  

   region 
  northward 
  from 
  Schenectady. 
  Various 
  accumulations 
  that 
  

   may 
  be 
  called 
  recessional 
  are 
  found 
  in 
  the 
  Sacandaga 
  region, 
  espe- 
  

   cially 
  in 
  the 
  neighborhood 
  of 
  Osborne's 
  bridge 
  and 
  northward 
  but 
  

   more 
  especially 
  in 
  the 
  Sacandaga 
  valley 
  northward 
  from 
  Northville 
  

   and 
  northward 
  from 
  Edinburg. 
  Here 
  are 
  two 
  great 
  accumulations 
  

   of 
  constructional 
  hills 
  of 
  sand 
  and 
  gravel 
  which 
  may 
  be 
  regarded 
  

   as 
  the 
  terminal 
  of 
  the 
  Sacandaga 
  glacier 
  at 
  that 
  stage 
  of 
  its 
  recession.
