I was up about a month ago. Blue sky, but at the Glencliff trailhead it was "snowing" lightly. Actually snow blowing off the summit. Met a guy coming down who said it was whiteout and he had to wait for the winds to die down to find the next cairn on the return. Said footprints were gone the second he made them. Met a young woman on the ridge who said essentially the same, although she downplayed it.
No footprints to follow at all once on the summit cone--drifting snow everywhere, although the underlying trail was packed down. Strong winds, and while not a complete white out, I could see someone being shaken by the experience. Face mask and goggles necessary for the return. Very few footprints to follow, only on the lee side of a rise. It was my twelfth separate month on the summit, almost entire from the Glencliff Trail, and even then, having been from that direction so many times, it was still a struggle to find the path back down. I can easily see how someone could lose the trail.
Dang! You know, you drive up, you hike up, you see conditions you don't like, but the summit seems so close. You know you don't like the conditions, and yet, it's so hard to make the call the turn around...
