Time: 5:30-7:30 pm
Location: Camassia Nature Preserve, 5000 Walnut St, West Linn, OR
Leader: Jason Clinch (NPSO)

Easy one-mile hike through a Nature Conservancy preserve named for the common camas (Camassia quamash) which profusely blooms here in April and early May, this preserve hosts more than 300 plant species. The rocky plateau was exposed 12,000- 19,000 years ago when the Bretz Floods or Missoula Floods poured down the present Columbia River Gorge and far into the Willamette Valley. The floods swept soil and vegetation from parts of the valley and deposited granitic boulders (called “glacial erratics”) from as far away as Canada Meet us at the entrance at 5000 Walnut Street, West Linn, OR 97068. This hike is limited to 12 people and parking is very limited so please carpool. The preserve is small so you may be able to still join the group if running late. Registration is required; contact Jason at for more information or to sign-up.
