Multnomah Falls on the Oregon side of the Columbia River is, at 620 feet, higher than Niagara Falls, although obviously nowhere near as wide. It drops into a pond at the bottom of a gorge it's carved out over the millennia, and then spills out of that down into a little stream that takes its water to the great Columbia.
A salmon wheel, more exactly a machine to catch (or scoop up) salmon from the river and deposit them, without damaging them in any way, into a holding basin to be picked up later and processed either by a native tribe into dried salmon, or canned for national distribution.
Stone bowl in the form of a turtle, the work of one of the area's Native American artisans of the early 20th century.
Just downstream of the big Bonneville Dam stands this monolith, the core of an ancient volcano, on the Washington bank of the river. It was going to be blasted into rock for breakwaters but was saved by making it into a state park.
Beautiful and often odd stone formations exist all along the Columbia. This one on the Washington side was not too far east of Portland, Oregon.
Oregon's Mount Hood from the river.
In the town of St. Helens on the Oregon side of the river, a little monument to the famous Newfoundland that was a huge asset and helper to Lewis and Clark and their party on their historic exploration of discovery and contact with the native peoples of the Louisiana Purchase.
Looking north into Washington and the shattered remains of Mount St. Helens.
Approaching the mouth of the Columbia, this five mile long bridge connects the city of Astoria, Oregon with the Washington shore.
The Coast Guard Museum at Cape Disappointment has a decommissioned rescue boat exhibited at an angle common to the waves of the treacherous Columbia Bar where the river slams into the Pacific. These boats and their successors were made as unsinkable as possible, designed to be self-righting in roll-over situations and to survive tremendous strikes from the turbulent meeting of river and ocean.
Predominantly foggy and damp, the Columbia Bar area supports a semi-rain forest environment. Fungus growing on a rotting chunk of a downed tree.
