Map of possible route  It's about 20km roundtrip with 1500m elevation. Could be a bit more or less depending on how high we can drive.

There's some change the Mamquam FSR will be blocked by snow or a washout well before its end. In that case, we'll go to another destination off the Mamquam, maybe Alpen. 

Expect firm, icy snow, and challenging skiing. Consider bringing ski crampons and maybe other pointy things.
