  • Elevation Gain: 2,500 ft

Meet at the Eastgate Park and Ride NW corner (47.581157, -122.15317), near 140th Ave SE, west of the parking structure at 6:30 am.  This is also where the Crystal ski bus meets, so look for me in a cowboy hat and tan crew cab pick-up truck.  From there, we can form ride shares if desired and drive up to park at the Snoqualmie West parking area off of Exit 52.

This will be a moderate skin approach heading through protected woods to Kendall Knob 2 above the Kendall Peaks Lakes Basin.  It is roughly 1700 ft of skinning in less than 3 miles.  From there we can decide which direction to ski based on the snow conditions and make laps of it for roughly 3000 ft.
