East Sunset Trailhead parking lot in Issaquah at 7:30 AM. It is 100 yards south of I-90 at exit #18.  The address is 665 E Sunset Way, Issaquah, WA.  If you are coming up SR-18, we will either meet you in North Bend.  We will work that out the day before the trip.

If we don't get a big dump of snow, the trail to Mason Lake and maybe beyond to Rainbow Lake should still be hikable.  Here is the summer WTA description

In the event of packed snow on the trail or no more than a few inches of fresh snow, we will proceed.  But this won't be a trip where we take or wish we took snowshoes.

Required Equipment:

- 10 essentials

- Must have traction devices such as MicroSpikes.

- Must have waterproof boots, gaiters and poles.

- You must also bring a puffy jacket, winter gloves, winter cap and insulating sit pad.


In the event of a forecast for lousy weather on Monday, this trip might be postponed until Wednesday or Friday, OR changed to a Tiger / Squak / Cougar area hike OR maybe both of those.
I will notify everybody by email by Saturday if I decide to make that change.  Email me your suggestions on Friday if you want some input in the decision.
By signing up for this trip, you agree to this flexibility.
