The one thing my friend and I learned last fall is that the whole mountain “may be clear” but the north side switchbacks can retain snow and ice. Even just the half inch of ice on the switchbacks was sketch. On the Dry Lake side, particularly the upper Sky High switchbacks are fairly narrow as it is and have a dangerous runout in snow. Also there sometimes is a snow field around Mineshaft Flat up high as the trail cuts across a scree field (top part of the Dry Lake side). One time when it was there but other areas burned out (no snow), we cut the corner before the crusty icy snow field and went up cross country to the peak.
Best to do South Fork/Dollar/Dry with someone who knows it in winter conditions.
