Extended Data Fig. 7: Stratigraphic correlations across different profiles in X-12.
From: Evidence of human occupation in Mexico around the Last Glacial Maximum
a, b, Excavation grid diagram (a) and maximum-depth diagram (b) showing the position of the profiles depicted below. For correlation reasons, all profiles show the upper contact of stratum 1210 with 1212 marked with a white contour. The position of OSL samples is indicated (labels beginning with X-). c, South profile, squares K2, K3, L2 and L3. d, South profile, square H2. e, South profile, square G2. f, South profile, square F2. g, South profile, squares M3, M4, N3 and N4. h, West profile, square J4. i, West profile, squares I5 and I6. j, Eastern profile, squares M4, M5 and M6 (profile removed during the 2016–2017 winter excavations). k, Eastern profile, squares N4, N5 and N6 (new eastern profile after the excavation of the one shown in j).
