Lassen NP can also have snow canyons[1] after they plow the snow in late spring. Nothing like 60' but 20'

Edit, looks like your sierra ref is mostly about Lassen which is not really the sierras but an old volcano n.west of them.

We don't get huge amounts of snow in Scotland but we do get a lot of wind which can pack the snow into gullies giving impressive snow depths - I've seen claims of over 30m in places (the Ciste Gully on Cairngorm), the Cairngorm access road also has problems with snow as it tends to completely fill up at various places.

Very frustrating not being able to ski because of too much snow!

The tendency for what snow we do get to blow off elsewhere is why ski areas in Scotland have huge amounts of snow fencing (they are all above the treeline) to try and trap the snow in place.
