Tronsen Ridge (winter)

Tronsen Ridge runs north from Blewett Pass to the east of Route 97. It offers several options for winter scrambling when snow blocks many mountain access roads and the weather on the west slopes of the Cascades is unfavorable. The area offers a generally open understory, moderate slopes and good views.
