This sign is found at the tip of Kelly Point in Portland, at the confluence of the Columbia and Willamette Rivers. Due to the many large river islands that occupy the area, Lewis and Clark missed the Willamette River twice, once on the way to and again on the way back from the Pacific Ocean. The Willamette is the second largest watershed in what later became the Oregon Territory (and later became Oregon, Washington, Idaho) not to mention British Columbia (pictures are really big, click for full size):
Snaps from Kelly Point, where my wife and I went walking yesterday. Google shots show context.
The place was empty- we saw one fisherman and one Heron. Mighty quiet.
The collage is followed by larger pictures.
