I've done a ton of weekend mountaineering trips with an older model north face prophet 45 litre. And I'm usually carrying the bulk of the common gear, tent, rope, rack, etc. My big pack (80 litre) only comes out for week long mountaineering trips or winter when I need more warm gear.
So I think you should be perfectly fine with a 50 litre pack. Mt Adams is a snow hike, you don't need much technical gear for it.
The greatest signature ever, tribute.
