  REGION 
  OF 
  SANTA 
  V 
  N 
  KZ 
  MOUNTAINS. 
  

  

  AREA 
  SOUTH 
  OF 
  LOMPOC. 
  

  

  South 
  of 
  the 
  Lompoc 
  Valley, 
  the 
  Monterey 
  dips 
  in 
  general 
  north- 
  

   ward 
  away 
  from 
  the 
  higher 
  portion 
  of 
  the 
  hills, 
  but 
  south 
  of 
  the 
  

   town 
  of 
  Lompoc 
  is 
  an 
  area 
  of 
  much 
  disturbance, 
  and 
  many 
  folds 
  

   have 
  heen 
  developed 
  on 
  the 
  flank 
  of 
  what 
  may 
  be 
  thus 
  broadly 
  con- 
  

   sidered 
  as 
  a 
  monocline. 
  These 
  folds 
  have 
  been 
  compressed 
  in 
  dif- 
  

   ferent 
  directions 
  and 
  there 
  is 
  a 
  puzzling 
  diversity 
  of 
  dip 
  and 
  strike. 
  

   There 
  are 
  so 
  many 
  local 
  folds 
  that 
  it 
  is 
  difficult 
  to 
  connect 
  the 
  more 
  

   important 
  axes, 
  but 
  the 
  general 
  lines 
  of 
  disturbance 
  are 
  continuous 
  

   for 
  the 
  distance 
  mapped. 
  The 
  main 
  folds 
  south 
  of 
  Lompoc 
  are 
  an 
  

   anticline 
  near 
  the 
  valley 
  and 
  a 
  syncline 
  north 
  of 
  the 
  Monfcerey- 
  

   Vaqueros 
  contact, 
  with 
  a 
  minor 
  anticline 
  and 
  syncline 
  between. 
  

   The 
  attitude 
  of 
  the 
  beds 
  is 
  extremely 
  variable, 
  the 
  dip 
  ranging 
  in 
  

   general 
  between 
  15° 
  and 
  60°. 
  On 
  either 
  side 
  of 
  the 
  main 
  anticline 
  

   between 
  Salsipuedes 
  and 
  San 
  Miguelito 
  creeks 
  the 
  hard 
  shales 
  dip 
  

   away 
  at 
  an 
  angle 
  of 
  20° 
  to 
  40°. 
  West 
  of 
  San 
  Miguelito 
  Creek 
  the 
  

   folds 
  swing 
  out 
  toward 
  the 
  valley 
  or 
  die 
  out 
  on 
  the 
  flank 
  of 
  the 
  mono- 
  

   cline, 
  which 
  thus 
  becomes 
  unbroken. 
  

  

  The 
  greater 
  part 
  of 
  the 
  strata 
  in 
  the 
  hills 
  south 
  of 
  Lompoc 
  belong 
  

   low 
  in 
  the 
  Monterey 
  formation, 
  although 
  higher 
  portions 
  remain 
  in 
  

   the 
  synclinal 
  folds. 
  The 
  disturbance 
  has 
  been 
  considerable, 
  and 
  

   erosion 
  has 
  removed 
  the 
  highest 
  parts 
  of 
  the 
  formation, 
  so 
  that 
  the 
  

   chances 
  have 
  been 
  good 
  for 
  the 
  escape 
  of 
  any 
  oil 
  that 
  may 
  have 
  

   been 
  present. 
  There 
  are 
  no 
  surface 
  indications 
  of 
  petroleum 
  and 
  

   the 
  conclusion 
  is 
  that 
  no 
  great 
  quantity 
  of 
  oil 
  would 
  be 
  found 
  on 
  

  

  drilling. 
  

  

  AREA 
  OF 
  SANTA 
  RITA 
  HILLS. 
  

  

  East 
  of 
  Lompoc 
  the 
  lines 
  of 
  structure 
  cross 
  the 
  Santa 
  Ynez 
  Valley 
  

   into 
  the 
  Santa 
  Rita 
  Hills. 
  These 
  hills 
  are 
  formed 
  of 
  a 
  single 
  main 
  

   ridge 
  which 
  is 
  paralleled 
  on 
  the 
  south 
  side 
  by 
  an 
  important 
  anticline. 
  

   The 
  dips 
  on 
  either 
  side 
  of 
  the 
  broad 
  summit 
  of 
  this 
  fold 
  range 
  from 
  

   a 
  few 
  degrees 
  to 
  about 
  35°. 
  The 
  general 
  trend 
  of 
  the 
  fold 
  is 
  east 
  and 
  

   west, 
  in 
  conformity 
  with 
  that 
  of 
  the 
  Santa 
  Ynez 
  Range, 
  but 
  it 
  is 
  

   curved, 
  especially 
  at 
  the 
  east 
  end, 
  as 
  if 
  influenced 
  by 
  more 
  than 
  one 
  

   set 
  of 
  forces. 
  Other 
  important 
  folds 
  occur 
  on 
  the 
  flanks 
  of 
  the 
  anti- 
  

   cline, 
  giving 
  origin 
  to 
  the 
  disturbed 
  zone 
  followed 
  by 
  Santa 
  Ynez 
  

   River. 
  

  

  a 
  Called 
  locally 
  Cat 
  Canyon.
