OverviewThis version of the route is based off of the Treasure Mountain Group Combination. It explains the traverse from Cinnamon Mountain B. It would be OK if you want to just summit this mountain, just make sure you follow JonBradford's explanation on the Yule Pass approach onto the SE Ridge route.
First off, I would like to thank Jon Bradford for the exceptional page on Treasury Mountain. As explained above, please follow the route description on the main page if you would like to just summit this one.
Coming from Cinnamon Mountain B, you can see the ridge going up to the summit of Treasury Mountain and it does not look to hard. It is not hard at all, the traverse is very fun and enjoyable, but requires some very easy Class 3 scrambling to the top of Treasury. This traverse gives you a fantastic veiw of the Raggeds Wilderness along with Paradise Basin, Yule Pass, and some of the Ruby Range. I would consider this one to be the first major summit of your trip starting from Emerald Lake.
Getting ThereIf you are doing the combination, you should of gotten to this point by traversing over from Mount Baldy to Cinnamon Mountain B.
(However, if you are not doing the traverse and just doing this individual summit, here is some info on getting there.
From Buena Vista, make a left onto US 285. From there make a right onto US 50 up and over Monarch Pass and continue onto Gunnison. From Gunnison go North onto US 135 to Crested Butte. From here, go up the road and make a left of Slate River Road. This road is suitable for passenger cars. Go all the way to the end of the road where you will find the cut-off for Paradise Divide. You will need a 4WD vehicle from this point. If you do not have one, you can hike up the road which is not very far. Once you are at the top of Paradise Divide, you will see a sign marking it and it's elevation. From here, continue towards the Yule Pass Trailhead.)
