Moving west in Colorado, the data from the earlier seasons is sketchy. Accordingly I compare two independent weather sites to ski areas not too far away that are 75-80% correlated.
Gothic and Aspen
Aspen did better with open terrain in 2025-26 than any of the areas I examined farther east in Colorado. I say both 1976-77 and 1980-81 were worse. Look at those meager maximum base depths and the first 4 months of snowfall at Gothic.
Red Mt. Pass and Telluride
2017-18 was worst for open terrain with the dreadful Nov/Dec. I'd guess that 1976-77 was a similar start and worst overall. If April 1977 was as much as average at Red Mt. Pass (which it was not at Gothic or Taos), 1976-77 would still be its driest season by a considerable margin.
Taos
By all measures 2017-18 is clearly Taos' worst season. Why was this year better with similar snowfall? I'd speculate that the snow had more water content as evidenced by the higher max base depth. Telluride may have benefited similarly. 1976-77 and 1980-81 weren't good but they were not as severe as at many places.
