Dustin, Matt and co. are right. The approach is long for a short climb, but the area is so beautiful, and the overall experience so great it's definitely worth it.
In summer, I used only a few cams (mid range sizes), a couple of stoppers and a large hex or two. Go up or down based on your experience on rock of that difficulty. Again, snow may change things, so if it was me, personally, I'd err on the side of more gear.
One thing to consider is getting off. On the summer it's 3 or 4 easy repels off the north side off blocks that are already slung with enough webbing, etc. to choke a donkey. It's possible that some of that stuff is snowed over so you may have to get creative. Somebody who has climbed it during this time of the season could probably be of more help.
Have fun and bring a camera!
