By the way, I always recommend going up to Rimrock/South Peak first, then looping over to the main summit. Same trailhead, but bear right/straight at the first trail junction to get to Rimrock. It makes for a fantastic loop and adds very little mileage. The scamper up to the main summit may be a mix of ice and rock right now, but with some creativity you shouldn't have a problem. It was pretty darn icy when I did it around New Years, but it may be a bit better now.
Enjoy it - a wonderful little hike!
