Since OpenSnow's only reporting November-April snow, it could well be that Targhee got 66-74 inches in October and May, so both sets of numbers might be accurate. Alta definitely followed their stellar April with more snow in May that season.Yea I agree with the Alfred E Neuman sentiments.(What, me worry?) The below was taken from liftopia.com blog rgarding snowfall amounts down in the westand substantially higher in the east during that winter. Thought I saw 309" on the GT site closing weekend. Don't remember for sure but doremember it as very sunny, warm, and sticky.
Wyoming, Montana and Idaho fared much like Colorado. Grand Targhee in Wyoming is about as reliable for snowfall as any U.S. resort. The ski area received a healthy 301 inches. Of course, it averages 500 inches, so 2014-15 was a down season by its high standards.
Like Grand Targhee, Utah resorts have huge annual snowfall averages. The 2014-15 season did not meet their high standards, but Alta Ski Area still tallied 324 inches. However, snowfall during the three months of January, February and March added up to just 98 inches. (Alta usually receives about that amount in each of those months.)
