Replying to How late in the season is Bear usually open until?

I've been wanting to go to California to ski for years now. I specifically want to shred Bear.

I work at a ski resort in the northeast, so I can't really take any vacation time during ski season. However, we usually close around early April.

Wondering how late in the season Bear is usually open until, what conditions are like in early-mid April and later, etc.

Thanks.
