Stem-and-leaf plot of all tree-ring dates for Structure 102. Each numeric digit in the bars of the histogram represents the final digit of one tree-ring date. For example, in the second bar from the bottom, there are four dates in the A.D. 1260s: 1261, 1264, 1264, and 1267. The last date and one of the 1264 dates are cutting dates.
