Analysing terrain data
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.
The Rock Garden is the first line you reach when taking the Aqueduct Trail to the north.
The top of the Rock Garden has some small, 5-15 foot features that can be jumped off of, but there is also a very obvious and easy entrance that requires no jumping.
The bottom half of the Rock Garden has a variety of similar small features that can be a lot of fun to link up in a row.
When the snow fills in right, there is a triangular shaped rock that is a great natural feature to backflip off of. Although it certainly has avalanche hazard, this line is less affected by the wind than the 80's directly to skier's right, and thus avalanches less often.
