This is a one-way hike! We'll start at Chinook Pass, hike up to Sheep Lake and Sourdough Gap, then drop down to Crystal Lakes and out to the Crystal Lakes trailhead. In the middle, we'll meet up with a second Mountaineer group that is starting at the Crystal Lakes trailhead and hiking through to Chinook Pass. We'll have lunch with the other group, swap car keys, and then reconvene back at the Crystal Lakes trailhead. 

Meet at 8 am at the Enumclaw Ranger Station.
