Sorry to kill your dreams, but this is the wrong year for you. Usually the season ends mid April, but the powers that be, in their infinate wisdom, have decided to shut up shop on April 6th this year. Apparently the date is set based on the date of Easter, which happens to be early in 2008. I don’t understand what that has to do with the weather, but that what’s been decided. I heard that it’s always been that way, but RCR have had the mountain for less than 10 years, so it’s hardly set in stone.
As far as conditions go, it’s a very mixed bag in April. Generally the end of March and April can go either way. I’ve had more than one knee-deep powder day in April, and we get snow dumps as late as May. That said, the base of the mountain is at under 1000m, so fairly low for spring skiing and yes, the lower slopes are usually a slushy mess for the last week or so – from halfway up it can be fantastic though, and the entire whitepass area feels like mid winter skiing right through till the end of April.
Upshot is you could easily get two and a half excellent weeks after March 20th, but then the lifts stop turning. If you’re into touring/hiking, there’ll still be plenty folk trudging up the mountain for at least a couple of weeks after that and you might find a backcountry buddy for more adventures.
