Meet at 8 AM Saturday at the Preston Park and Ride Lot east of Issaquah on the north side of I-90.

This is a unique and popular eastern Washington backpack trip, well suited to this time of year.  All water consumed from when we start hiking until we return to the trailhead must be carried in, because all lakes and streams we pass are from agricultural runoff which carries fertilizer chemicals that cannot be removed by filtering or treating the water.  For that reason we will only have one short day hike on Saturday after we set up camp.  We will hike out right after breakfast on Sunday and make an optional stop at Gingko Petrified Forest for a second day hike on a 3-mile trail passing petrified trees.  We can have an optional meal stop in Ellensburg on the drive home on Sunday.  It is estimated that we will be back to the Preston Park and Ride lot before 5 PM on Sunday.  A Discover Pass must be displayed by each car parked at the trailhead.
