Figure 6

Directional consistency of the sequoia samples measured in Pruhonice Paleomagnetic Laboratory. Solid symbols indicate positive inclination, and empty symbols negative inclination of natural remanent magnetization. Numbers denote relate to the following approximate ages: 1 = year 1650, 2 = year 1613, 3 = year 1495, 4 = year 1436, 5 = year 1389, 6 = year 1376, 7 = year 1352, 8 = year 1316, 9 = year 1285, 10 = year 1242, 11 = year 1224, 12 = year 1153, 13 = year 1138, 14 = year 1110, 15 = year 1059, 16 = year 1030, 17 = year 1003, 18 = year 974, 19 = year 899, 20 = year 851, 21 = year 818, 22 = year 782, 23 = year 747, 24 = year 720, 25 = year 691, 26 = year 660, 27 = year 613.
