looking for data

Does anyone know where I might be able to find historical data on operation by season by resort?

I am looking for number of days a resort was open say for the last 5 years. mostly looking at PNW but sources to anywhere in the US and Can would be helpful.

thanks,

With a little bit of digging you can probably find opening and closing dates of resorts and get some numbers. However, that of course wouldn't take into account any single-day closures due to weather/etc. I suppose it also depends on how many resorts you want to manually pull this data for.
