Captain Clark's "Wappato Island" lies across the confluence of the Willamette River - now called Sauvie Island, above left and right. Clark noted that, "from the entrance of this river, I can plainly See Mt Jefferson... S.E. Mt Hood East, Mt St Helens...." I could only see Mt Hood to the east from my vantage point at Kelly Point Park, near some Portland Harbor docks on the Columbia River. Right, blackberry flowers on the Willamette.
