The Doors (aka Tree Run) Map

A series of open glades, The Doors is thus named for its various "openings" in the trees. Officially this area is called Tree Run, but that name is losing popularity. Each "door" reveals another long open slope through this otherwise heavily treed slope. This is a great place to find good snow on a powder day. Once Green Valley and the Frontside are tracked up, head to The Doors and work the edges of the trees. You can often find a few fresh lines, but this popular run gets skied out by mid-morning. The first two doors offer the longest vertical, but end up in the tight trees above the Sunnyside Road. Watch for the transition onto this cat track, especially early season. The two right-hand doors offer more options, as you can head right into more open terrain above Lucky Shot when the trees tighten up. Either way, end up on Lucky Shot and continue to the bottom of Rainier Express for another lap.



Serious gradient of 30-38 degrees where a real risk of slipping exists.

Low Exposure (E1)

1 out of 4

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.
