Union Creek Trailhead.  

We will plan for 3 nights on the trail.  The specific campsites are subject to change both before and during the trip, depending on weather and trail conditions.  The tentative schedule is:

Thursday, Day 1:  Hike about 12.2 miles, gaining about 3,400 feet, and camp at Sheep Lake

Friday, Day 2:  Hike about 12.2 miles, gaining about 1,400 feet, and camp at Cougar Lake

Saturday, Day 3 – Hike about 10.9 miles, gaining about 1,600 feet, and pick up our car at the Mesatchee Creek Trailhead, pick up our other cars at the Union Creek Trail, and drive home.

Guide Books:  Backpacking Washington, Douglas Lorain.

Leader permission is required, which you can obtain by sending an e-mail to the leader.

I expect low overnight temperatures will be in the 30s. .  Rain should be expected, and you should bring rain coat, rain pants, and pack cover and clothes that will keep you warm when wet (no cotton!). The trip is subject to change or cancellation if the predicted weather is unusually poor.

Conditioning:  This trip requires excellent conditioning.  We will average about 2 mph on the trail, including breaks.  You should be able to climb Mt. Si with a full backpack in 3 hours or less, and be able to repeat the climb on the next day.

Other gear notes:

1. Bear canisters are not required.  We will hang our food each night.   I plan to bring my Ursack. 

2. You should bring some method of water purification.

3. Bugs are certainly possible; bring bug repellant.

4. To reduce pack weight, you should consider sharing gear, especially stoves, cooking pots, water filters, and tents. About 2 weeks before the trip, I will send an E-mail to all. If you are interested in sharing any items, Reply All to this E-mail, describing gear you would like to provide for sharing or if you are interested in sharing another’s gear. Sharers should make arrangements directly with any interested people.
