To access this line, hike to the Summit of Peak 7.
Once you get to the top, you will see a sign for the Dunes.
You are basically skiing off the summit of Peak 7 towards Peak 6.
The Dunes tends to build up with a wind drifts and wind blown snow so conditions may vary.
Make your way to the base of the bowl.
From here, you have the option of skiing towards Peak 6 or back to Peak 7.
It is actually the fastest way to access Peak 6 from the top of the Imperial Chair on Peak 8 especially if you feel you need to get over to Peak 6 as fast as possible.
It can be a great ski if coverage and conditions permit.
