Fig 4. Chart comparing occupation surface size and various fire and lithic scatter placement scenarios.

Parameters: 1 fire, fire size 1, 4 lithic scatters, 30 occupations, 1% introduced lithics. Given the near identical results obtained for simulations using the FNP/LR and FNP/LU settings (blue), as well as for all simulations using the FR setting (green), for the sake of clarity these are shown here as single curves. FNP = Fire near previous, FR = Fires random, LSNF = Lithic scatters near fire, LSR = Lithics scatters random, LR = Lithics random, LU = Lithics uniform, TB = Thermal buffering.
