﻿IN" 
  THE 
  CONTORTED

  The 
  Geological 
  Position 
  of 
  the 
  Cromer 
  Till 
  and 
  Contorted 
  Drift. 
  

  

  The 
  relations 
  of 
  the 
  glacial 
  beds 
  to 
  those 
  below 
  can 
  best 
  be 
  seen 
  

   by 
  commencing 
  at 
  "Weybourne 
  and 
  walking 
  eastwards 
  towards 
  

   Cromer. 
  The 
  Chalk 
  forming 
  a 
  basement 
  bed 
  for 
  the 
  whole 
  of 
  the 
  

   Pliocene 
  and 
  Post-pliocene 
  deposits, 
  is 
  here 
  seen 
  in 
  the 
  cliff. 
  

   Eesting 
  upon 
  it 
  is 
  a 
  bed 
  called 
  " 
  iron 
  pan," 
  composed 
  of 
  flints 
  and 
  

   shells, 
  cemented 
  together 
  with 
  ferruginous 
  matter. 
  Above 
  this 
  are 
  

   a 
  series 
  of 
  laminated 
  sands 
  and 
  clays 
  called, 
  by 
  Mr. 
  H. 
  B. 
  Wood- 
  

   ward, 
  Weybourne 
  Crag, 
  and 
  thought 
  by 
  him 
  to 
  be 
  the 
  upper 
  part 
  of 
  

   the 
  Norwich 
  Crag, 
  but 
  considered 
  by 
  Mr. 
  J. 
  H. 
  Blake 
  to 
  be 
  the 
  equi- 
  

   valent 
  of 
  the 
  Chillesford 
  Clay, 
  and 
  identical 
  with 
  that 
  below 
  his 
  

   " 
  rootlet-bed 
  " 
  at 
  Kessingland*. 
  Above 
  the 
  laminated 
  sands 
  and 
  

   clays 
  is 
  a 
  bed 
  corresponding 
  in 
  appearance 
  with 
  the 
  " 
  rootlet-bed 
  " 
  

   at 
  Kessingland 
  ; 
  and 
  upon 
  it 
  rests 
  the 
  Contorted 
  Drift, 
  which 
  is 
  not 
  

   very 
  striking 
  at 
  this 
  end 
  of 
  the 
  cliff 
  section; 
  but 
  as 
  we 
  proceed 
  

   towards 
  Sherringham 
  it 
  comes 
  in 
  with 
  greater 
  force. 
  The 
  lami- 
  

   nated 
  sands 
  and 
  clays 
  are 
  to 
  be 
  seen 
  at 
  various 
  points, 
  even 
  be3^ond 
  

   Sherringham, 
  forming 
  the 
  base 
  of 
  the 
  glacial 
  deposits, 
  though, 
  as 
  

   the 
  cliffs 
  are 
  so 
  obscured 
  by 
  talus, 
  I 
  could 
  not 
  aver 
  that 
  their 
  conti- 
  

   nuity 
  was 
  not 
  broken 
  in 
  places; 
  indeed, 
  if 
  we 
  refer 
  to
