Description
Table Mountain has been the site of many slides in the centuries since the Missoula Floods. The largest of these was somewhere between 1100 and 1700. This slide removed the entire southern face of the mountain, damned the Columbia River and created the large, tumbled flat piece of land north of today's Bonneville Dam.
Since the big slide, there have been several smaller slides at Table Mountain and nearby Greenleaf Peak. These slides have created large aprons of loose material too fresh to support a forest. This location is where the abandoned road now known as the Two Chiefs Trail crosses the largest open slide zone.
