Expert Riders and Skier Recommendations:
Mary's Nipple: For those willing to do a little bit of hiking you can explore the large powder bowl off of Mary's Nipple and some amazing views of the Tetons. To get to Mary's you will take Dreamcatcher Lift to the top and then head south along the edge of the resort to Scotty's Gate. At the gate you will find out if Mary's is open. Once you pass through the gate you will have a 1/4 mile hike and about 300ft of climbing. The skiing is well worth the effort.
Toilet Bowl and Das Boot: At the top of the Sacajawea lift you will find some expert lines to the north. These two bowls are steep and you will find yourself working around some cliff bands or launching off of them. It is a nice rowdy time for those with the skills to pull it off.
