Stem-and-leaf plot of all tree-ring dates for Structure 1501. Each numeric digit in the bars of the histogram represents the final digit of one tree-ring date. For example, in the seventh row from the bottom, there are four dates in the A.D. 1200s: 1200, 1202, 1203, and 1209. The second date is a cutting date.
