The exposure grade does not take into account objective hazards (stone fall, seracs, etc) but only the consequences of the skier falling.

Low Exposure (E1): Exposure is limited to that of the slope itself. Getting hurt is still likely if the slope is steep and/or the snow is hard.

Medium Exposure (E2): As well as the slope itself, there are some obstacles (such as rock outcrops) which could aggravate injury.

High Exposure (E3): In case of a fall, death is highly likely.

Extreme Exposure (E4): In case of a fall, the skier faces certain death.

As well as the slope itself, there are some obstacles (such as rock outcrops) which could aggravate injury.


Granite Canyon is comprised of numerous north facing couloirs, massive cliffs, technical terrain, and everything is steep.

Each run ends abruptly as you collide into Granite Creek at the bottom of the canyon.


Runs in this area are highly consequential, cell service is spotty, and it’s a long way back to civilization.

Please respect this area.

It is optimal to ski with partners with experience in technical terrain and who know the area.

Many lines appear to “go through,” but in fact, they close out with an enormous cliff drop.

Likewise, Granite Canyon is popular with seasoned experts as well as first timers; following tracks blindly may put you somewhere you do not belong.

Approach all terrain in Granite Canyon with extreme caution.

To exit Granite Canyon, follow the traverse paralleling the creek bottom heading east.

Gain height when possible (sidestepping, skating, and poling when necessary) until you round the corner of Apres Vous Mountain.

From the corner, continue the traverse southward, you should end up on a cat track leading through a housing development which will bring you back to the base of the resort.

CAUTION: the traverse out of Granite Canyon will place you in the bottom of numerous avalanche paths.

Be aware of overhead dangers, and choose resting spots wisely! Endless is not only long, steep, and sustained, it’s one of the easiest Granite Canyon runs to access.

Don’t be fooled by the ease of access though, this run has serious potential for disastrous consequences.

From backcountry gate #6 (at the north end of Casper Bowl), scoot past the gate until you reach the edge of a large bowl.

This bowl will funnel you into Endless couloir.

Keep the cliff prow on your right as you descend and ride the gut until you reach the exit traverse thousands of feet below.

Just below the prominent cliff prow, it possible to scoot to the skier’s right to link up with Mile Long couloir.
