Fig. 4. Predicted walkers reaching archaeological sites and associated sites occupations from mechanistic simulations.

a Distribution of walkers around chosen archaeological sites⁹ (Supplementary Table 1) for the northern and southern entry points (left and right respectively) combining 5000 simulations in each case and showing percentages of time the sites are visited. b Analysis of the number of walkers in a 10 km radius around each site extracted by counting the walkers per simulation and showing the distribution extent and its mean (green circle – calculation is performed for each route). c Associated occupation number representing distinct visits to sites for each route. The distribution is calculated for the 5000 simulations after extracting the number of visits for each realisation (orange circle presenting the maximum number of visits).
