  along 
  a 
  considerable 
  extent 
  of 
  its 
  northern 
  (lank. 
  Tn 
  the 
  region 
  of 
  

   the 
  Pezzoni 
  well 
  an 
  unproductive 
  oil 
  and 
  gas 
  bed 
  is 
  encountered 
  at 
  

   about 
  1,200 
  feel 
  below 
  the 
  surface, 
  immediately 
  followed 
  by 
  a 
  dia- 
  

   base 
  or 
  lava 
  lock 
  in 
  which 
  the 
  ferromagnesian 
  minerals 
  have 
  been 
  

   weathered 
  to 
  serpentine. 
  In 
  the 
  Williams 
  well 
  the 
  same 
  or 
  a 
  similar 
  

   oil 
  and 
  gas 
  bed 
  occurs 
  much 
  lower. 
  The 
  well 
  was 
  abandoned 
  owing 
  

   to 
  the 
  terrific 
  gas 
  pressure, 
  which 
  heaved 
  heavy 
  tar 
  up 
  into 
  the 
  hole 
  

   and 
  stopped 
  operations. 
  The 
  Palmer 
  well 
  is 
  productive, 
  yielding 
  oil 
  

   of 
  L6° 
  or 
  17° 
  gravity. 
  Although 
  not 
  directly 
  associated 
  with 
  the 
  

   minor

  occur-] 
  

   ring 
  at 
  Fugler 
  Point, 
  1 
  mile 
  north 
  of 
  Gary, 
  is 
  important 
  in 
  indicating 
  

   the 
  probable 
  presence 
  of 
  petroleum 
  in 
  the 
  upper

  Conclusions 
  regarding 
  future 
  development. 
  — 
  The 
  region 
  north 
  of 
  the 
  

   Gato 
  Ridge 
  anticline, 
  from 
  the 
  vicinity 
  of 
  Cuaslui 
  Creek 
  westward 
  to 
  

   a 
  point 
  at 
  least 
  a 
  mile 
  beyond 
  the 
  Howard 
  Canyon 
  road, 
  is 
  underlain 
  

   by 
  strata 
  so 
  nearly 
  horizontal 
  as 
  to 
  preclude 
  their 
  containing 
  very 
  

   productive 
  accumulations 
  of 
  petroleum. 
  North 
  and 
  northwest 
  of 
  

   this 
  region, 
  however, 
  especially 
  near 
  the 
  axes 
  of 
  the 
  Gato 
  Ridge 
  

   anticline 
  and 
  the 
  anticline 
  north 
  of 
  it, 
  the 
  indications 
  are 
  good 
  for 
  

   productive 
  wells. 
  The 
  conditions 
  for 
  the 
  accumulation 
  of 
  petro- 
  

   leum 
  are 
  also 
  good 
  along 
  and 
  just 
  south 
  of 
  the 
  axis 
  of 
  the 
  Gato 
  Ridge 
  

   anticline 
  in 
  the 
  vicinity 
  of 
  Cuaslui 
  Creek 
  and 
  from 
  this 
  locality 
  west- 
  

   ward 
  to 
  the 
  upper 
  portion 
  of 
  Canada 
  de 
  los 
  Coches. 
  Tin 
  4 
  same 
  might 
  

   be 
  said 
  of 
  the 
  immediate 
  vicinity 
  of 
  the 
  row 
  of 
  prominent 
  knobs 
  

   which 
  extend 
  in 
  a 
  straight 
  line 
  northwestward 
  for 
  5 
  miles 
  from 
  a 
  

   point 
  about 
  a 
  mile 
  north 
  of 
  Los 
  Alamos, 
  and 
  possibly 
  also, 
  but 
  in 
  a 
  

   less 
  degree, 
  for 
  the 
  territory 
  between 
  these 
  knobs 
  and 
  the 
  axis 
  of 
  the 
  

   anticline. 
  These 
  knobs 
  mark 
  an 
  abrupt 
  change 
  in 
  the 
  dip 
  of 
  the 
  

   beds 
  from 
  3° 
  to 
  12° 
  SW. 
  to 
  35° 
  or 
  40° 
  or 
  possibly 
  more, 
  in 
  the 
  same 
  

   direction. 
  Wells 
  would 
  have 
  to 
  be 
  sunk 
  to 
  a 
  considerable 
  depth 
  

   along 
  this 
  last-mentioned 
  line 
  to 
  reach 
  the 
  oil 
  horizons, 
  but 
  if 
  oil 
  was 
  

   encountered 
  at 
  all 
  it 
  would 
  probably 
  be 
  in 
  such 
  quantities 
  as 
  to 
  pay 
  

   for 
  the 
  deep 
  holes.

  CREEK-LISQUE 
  CREEK 
  ANTICLINE. 
  

  

  Structure. 
  — 
  The 
  La 
  Zaca 
  Creek-Lisque 
  Creek 
  anticline 
  extends 
  from 
  

   the 
  ridge 
  southeast 
  of 
  Canada 
  del 
  Comasa 
  southeastward 
  at 
  least 
  as 
  

   far 
  as 
  the 
  edge 
  of 
  the 
  Lompoc 
  quadrangle 
  east 
  of 
  Santa 
  Agueda 
  

   Creek. 
  Its 
  course 
  is 
  practically 
  straight 
  except 
  at 
  the 
  northwestern 
  

   ext 
  remity, 
  which 
  bows 
  around 
  toward 
  the 
  southwest 
  and 
  is 
  en 
  echelon 
  

   with 
  the 
  east 
  end 
  of 
  the 
  Gato 
  Ridge 
  anticline. 
  The 
  dips 
  along 
  the 
  

   axis 
  are 
  low 
  in 
  both 
  directions, 
  but 
  distant 
  from 
  it 
  they 
  are 
  much 
  

   steeper, 
  being 
  as 
  high 
  as 
  30° 
  or 
  more 
  to 
  the 
  northeast 
  on 
  the 
  second
