Per the handbook:
At a minimum, be able to hike with a full day pack (20% of body weight but no less than 25 pounds and no more than 50 pounds) up the Mt. Si trail to the boulders (4 miles, 3400' gain) in under 2h
Please use water for the bulk of your pack weight to allow for a quick (and less painful) descent.
We will meet at the Mount Si trailhead, next to the picnic table and opposite the bathrooms. Ready to go at 7:30am.
