No way in a 2wd vehicle, and probably not in anything without tracks either.
I haven't gone up to check yet, but my son was up that way 4 weeks ago and the snow on MI Road was still about 6 feet deep a good 10 miles from the Quarry.
Based on last year, and barring any unusually hot / rainy weather up there, figure it will be late May at best before we can get to the Quarry.
ETA: The snow pack this year was 300% of normal.
