The Third Bowl and Phoenix Exit is a groomed cat road across the bottom of the 3rd Bowl, Phoenix Bowl, and Staircase to get back to the East River Lift.
Where ever you end up at the bottom, turn left under the road and try to keep your speed.
The road has fifty yards of slight uphill before a clearing at the bottom of the Staircase.
From there, take a right off the road and follow a traverse through the trees (do not cross the boundary rope, as you'd end up at the bottom of the East River Valley, stuck).
This eventually leads back to a cat road, which dumps you out on East River Lift's Black Eagle.
