  Figuee

  Tentatively 
  reconstructed 
  distribution 
  of 
  South 
  American 
  Sierral, 
  

   Silval, 
  and 
  Marginal 
  culture, 
  as 
  of 
  circa 
  A. 
  D. 
  1000, 
  and 
  major 
  cultural 
  dif- 
  

   fusions 
  and 
  drifts 
  since 
  then. 
  Marginal 
  enclaves 
  within 
  the 
  Silval 
  belt 
  are 
  

   not 
  included 
  in 
  map. 
  Araucanian 
  territory 
  is 
  placed 
  in 
  the 
  Marginal 
  area, 
  

   although 
  horticulture 
  may 
  possibly 
  have 
  reached 
  that 
  far 
  south 
  by 
  A. 
  D. 
  1000.
