Skiing couloirs and Mt Cheeseman ski area generally don't go together, but there are some fun short shots to be had.
Gun Barrel (D4, I, R1)
This is the big obvious one as you get into the car park. Access is easy, the entrance is between tower 3 and 4of the main T-bar and a short traverse brings you back to the car park.
No need for a red line to mark this one out.
The A-Basin Chutes (D5/6, I, R2)
These are a little more interesting. The entrance is reached with a high traverse above A-Basin. From here two main descent options are on offer, with skiers right couloir being the pick of the two. There are a few more variations for those who are creative and enjoy kick turns and stepping over rocks.

These two little guys can introduce a newbie to the narrow stuff and give some good opportunities to work on some skills especially for those without touring bindings/skins and the avalanche know how to be in the backcountry.
