Left just before 6 AM on the trail, only to see our summit shrowded in a growing clouds, as we moved upwards. We pushed on and summitted through very high winds along the ridge lines. No view, but we imagined what it would be like. On the way back down the snow came quick and hard - 6 - 10 inches in an hour, with drifting on the trails. Road from the kilns to the campground are pretty bad. We made it in a 2 wheel drive car, but in retrospect, like the park rangers - recommend a 4x4 high clearance.
