The Terminal Cancer Couloir is a bucket list line for many backcountry riders for a good reason. Tucked into the deeply glaciated Lamoille Canyon, the mere sight of Terminal Cancer Couloir beckons one to climb and ride it. The Ruby Mountains are Nevada's wettest mountain range, and good snow can almost always be found above 8,000 feet during the winter months.

The approach is straightforward: Simply ski or drive, depending on the snow pack, up Lamoille Canyon road until you see the couloir on the south side of the road. Find a safe place to cross the creek and skin up through thick aspen trees and continue up slope until the couloir comes into view. Skin to the base of the couloir, at which point you can either boot pack or skin depending on preference and conditions.

The couloir ranges from 25 to 40 degrees. Most of the couloir is pretty narrow, which makes for some exciting turns down. About half way down the line the couloir opens up and allows for more playful turns up on the banks of the walls. The end of the couloir opens up into a gully that leads straight back down to the creek.

Extremely cool run. Make sure to have crampons for the boot pack. Do not go alone. Rock avalanches were more common than snow avalanches at the time. Getting into the coulior from the base is the hardest part due to steepness and ice.
