I had that in the October storm for about 4-5 hours straight or so. Not quite as long as Mitch, but long anough to pile up 28", IIRC. A beautiful powder storm up this way. No leaves on the trees up here to cause issues even if it hadn't been powdery.
Oct 11 was one of my favorites of all time. The combination of a block buster storm, the first storm of the season, and actually not being in season mark it as memorable.
