Although this is the smallest peak accessible from Yankee Boy Basin, the climb offers plenty of fun routes and gorgeous views!

Stony Mountain is the first major peak that you'll see as you drive into Yankee Boy Basin. Parking on the road parallel to the peak would be best, making the amount of bushwhacking as minimal as possible. 

Start your way towards the base of the mountain. This might mean crossing creeks and digging through tall plants, depending on what month you go. Once you reach the obvious avalanche path, covered in scree and boulders, curve around left. Going diagonally up, head around to the right of the base to the backside. 

There is a faint trail leading up to the ridge line. By taking this, you will end up on the ridge and have to do some up & down scrambling to find your way to the true summit. This is also the shortest, and probably safest way. 

Be aware of falling rock, and where you put your hands & feet. It takes about 20-30 minutes to get from the starting end of the ridge, to the true summit.

At the top, you will not only be rewarded with 360 degree views of Yankee Boy Basin, Mt Sneffels, Mt Emma, Potosi Peak, Teakettle & Coffeepot Peaks, but also a cairn and a tiny summit log...also maybe some wildlife.

On the way down, there is a route down the front face, but this means very careful footing and more caution regarding falling rock. If you choose to go this way, follow the faint path going down through one of the chutes. It will be the only one that does no obviously cliff out. 

You can also choose to return as you came. This is a more relaxed descent.
