Tree-ring Reconstructions of Snowpack

Fig. 2. Tree-ring reconstructions of snowpack (black line). (modified from Figure 4 in Brice et al.,2021). Top: Chuska Mountains (1656–2015), Bottom: Williams Ski Run (1694-2015). Observed snowpack is in purple. The long-term average is the brown line. The green line is a 20-year smoothed series reflecting multi-year periods of above or below average conditions, which are highlighted in blue or yellow bars, respectively. The most extreme snow droughts are along the top of each plot, and the single driest year in each reconstruction is indicated in purple.
