Monday Geophoto: Willamette Falls

Willamette Falls, at Oregon City, Oregon, is the second largest waterfall in the US (after Niagara), in terms of volume. It's height is only 40 feet, but that's still enough of a hydraulic head to have made this an early industrial center (waterpower) in the Oregon Territory, and it remains so today. The bedrock here is Columbia River Basalt. More information here.
