Activity Notes

B-2, 10.8 miles, 1390 ft. elevation gain/loss, meetup in Vancouver, WA @ the 99th St Transit Center/Park & Ride, look for a white SUV with the back hatch open. We will hike completely around Coldwater Lake (formed in the aftermath of the eruption). The terrain is varied with areas of meadows, wildflowers, views, a waterfall, forested lakeside trail and a visit to the Tractor Junction (an area with heavy equipment caught in the blast). Bring a lunch/snacks for the trail and at least 3-4 liters of water. To register go to and follow the directions. Non-members welcome. We will carpool to the trail head so be prepared to take your turn driving. The carpool cost is 10 cents per person per mile. I am looking forward to hiking with you on this special trail. Questions: email
