Compare the tree ring record of precipitation in New Mexico graphed here with the same interval of the record from Wyoming illustrated in Figure 16.28. How do the records compare, and what does this imply about drought conditions in the West during this time period?

Figure 16.28 Northern Wyoming precipitation record determined from tree ring analysis. Precipitation records from 1895 onward were matched with tree ring widths to estimate precipitation values for pre-1895 tree rings. The dashed horizontal line represents the average precipitation determined from a century-long instrument record database. What patterns can you identify in the graph?
