Analysing terrain data
0 - 1
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.
Park at the Argenta pull-out on the S side, 7.1 miles up Big Cottonwood Canyon road.
Cross the creek and skin up the huge Argenta slide path trending to the right.
In the upper bowl head towards the W and gain the ridge, then follow this to the summit.
From the summit head N and E down the ridge.
There are several excellent tree lined gullies you can choose from at this point.
These will dump you down onto the lower slide path.
From here enjoy the playful terrain and halfpipes that lead right back down to the road.
The smaller trees are growing in pretty thick now and you can avoid some of them by ducking into the pines on either side of the run.
Another option for descent is backtracking on the skin track to the W ridge, and then dropping in through the steep pines into the main avalanche path.
