Due to Revelstokes low base elevation. It relies more heavily on the seasonal swing than elevation to provide cold temperatures. They built the base on the Columbia river. The largest river in the NW. If I know anything about gravity, it's that water flows down hill. A large river like the columbia is literally the lowest valley bottom in the entire region.
Having said that, with 6000 vertical feet. It can be quite warm down on the river. Yet still hold powder snow on the upper mountain. It's pretty awesome to be skiing below zero, cold snow up high, then down at the bottom and the sun is out and it's 12c/55F at the base.
If you're expecting cold, dry snow top to bottom with 30cm new overnight, then you are doing to have to get really luck. It doesn't happen in late march often.
Although the bottom elevation is not in it's prime, the backcountry is. So it really just comes down to the type of skiing you want to do, and what your expectations are.
