  LOCATION. 
  

  

  The 
  region 
  discussed 
  in 
  this 
  paper 
  is 
  situated 
  on 
  the 
  California 
  coast 
  

   in 
  Santa 
  Barbara 
  County, 
  between 
  120° 
  and 
  120° 
  40' 
  west 
  longitude 
  

   and 
  34° 
  30' 
  and 
  35° 
  north 
  latitude. 
  In 
  areal 
  extent 
  it 
  is 
  about 
  1,300 
  

   square 
  miles 
  and 
  it 
  practically 
  covers 
  the 
  Lompoc 
  and 
  Guadalupe 
  

   quadrangles 
  as 
  topographically 
  mapped 
  by 
  the 
  United 
  States 
  Geo- 
  

   logical 
  Survey. 
  It 
  includes 
  portions 
  of 
  the 
  San 
  Rafael 
  and 
  Santa 
  

   Ynez 
  divisions 
  of 
  the 
  Coast 
  Ranges 
  and 
  the 
  basin 
  region 
  lying 
  between 
  

   them, 
  which 
  is 
  occupied 
  by 
  the 
  Santa 
  Maria, 
  Los 
  Alamos, 
  and 
  Santa 
  

   Ynez 
  valleys 
  and 
  the 
  intervening 
  hill 
  ranges. 
  It 
  is 
  bordered 
  on 
  the 
  

   north 
  by 
  the 
  San 
  Luis 
  Obispo 
  County 
  line, 
  on 
  the 
  west 
  and 
  south 
  by 
  

   the 
  Pacific 
  Ocean, 
  and 
  on 
  the 
  east 
  by 
  the 
  Santa 
  Ynez 
  quadrangle, 
  

   which 
  covers 
  the 
  high, 
  wild 
  mountains 
  north 
  of 
  Santa 
  Barbara. 
  On 
  

   its 
  west 
  coast 
  are 
  Point 
  Sal 
  and 
  Point 
  Arguello, 
  and 
  the 
  south 
  coast 
  

   includes 
  Point 
  Conception 
  and 
  part 
  of 
  the 
  long, 
  straight 
  shore 
  line 
  

   that 
  runs 
  due 
  east 
  from 
  that 
  point 
  toward 
  Santa 
  Barbara. 
  These 
  are 
  

   among 
  the 
  most 
  prominent 
  coastal 
  features 
  of 
  California. 
  

  

  The 
  region 
  is 
  thoroughly 
  intersected 
  by 
  roads, 
  except 
  in 
  some 
  of 
  

   the 
  uninhabited 
  portions. 
  The 
  Southern 
  Pacific 
  Railroad 
  coast 
  line, 
  

   part 
  of 
  the 
  transcontinental 
  system, 
  extends 
  close 
  to 
  the 
  ocean 
  entirely 
  

   around 
  two 
  sides 
  of 
  the 
  area, 
  and 
  the 
  Pacific 
  Coast 
  Railroad, 
  a 
  local 
  

   line 
  from 
  Port 
  Harford 
  and 
  San 
  Luis 
  Obispo, 
  runs 
  into 
  the 
  region 
  as 
  

   far 
  as 
  Los 
  Olivos 
  via 
  Santa 
  Maria. 
  A 
  rough 
  estimate 
  would 
  place 
  

   the 
  number 
  of 
  inhabitants 
  of 
  this 
  region 
  between 
  5,000 
  and 
  10,000. 
  

  

  The 
  Arroyo 
  Grande 
  and 
  Huasna 
  oil 
  fields, 
  in 
  the 
  San 
  Luis 
  quad- 
  

   rangle, 
  San 
  Luis 
  Obispo 
  County, 
  are 
  also 
  briefly 
  mentioned, 
  although 
  

   not 
  a 
  part 
  of 
  the 
  region 
  whose 
  general 
  features 
  are 
  described 
  in 
  this 
  

   report.
