You can view this bundle in the Earth - A Work in Progress collection area.

Photo of the river and cliff faces on the Columbia River Gorge.  The basalt cliffs are Miocene (17-12 million years ago).  The gorge, however, was carved in the Pleistocene period (2 million - 700,000 years ago) and modified by the Missoula Flood (16,000 - 14,000 years ago).
