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.
Trestle Shot holds a bunch of lines around an old mining trestle that is great for photos.
Located in the middle North West aspect of Alta Lakes Basin above the Observatory, this area is perfect for mini hikes of around ten to twenty minutes, especially when avalanche conditions are high and it's good to stay away from risky faces.
There is a variety of short tree runs of varying pitches plus a couple of spots to build a backcountry kicker and lake view areas for picnicking.
There is no patrol so backcountry safety applies even in the mellow tree lines.
Snowmobiling is not uncommon during long weekends and holidays so shared area use and respect goes a long way to enjoying this part of the San Juan Mountains.
