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.
Rex's Rib is a real treat.
It has consistently steep and gnarly trees that you don't often get at Bridger Bowl.
It doesn't fill in until later in the year, and can be sporty even then.
It requires lots of hop turns and being in control.
It can get sun baked, especially later, but can hold amazing snow mid season and after a wetter snow.
You get to Rex's by going further skier's left once you are into the top of Job 2, or by heading right from the upper parts of Job 3.
The latter is a more technical approach.
Once here, you will have it all before your eyes; just barely off fall line turns, working to the left for 600 feet.
Have fun, but beware of sluffs, rocks, and pecker trees that may make your descent more difficult.
Rex's runs out into the bottom of Job 2 and the into the Z Fan.
