Table Mountain ...
Table Mountain is located on the Washington side of the Columbia River at River Mile (RM) 148, and rises above Stevenson, Washington and Cascade Locks, Oregon. Magnificent views of the peak and it's companion Greenleaf Peak are visible from many areas along the Columbia. Cascade Locks, on the Oregon side of the Columbia, has perhaps the best view of Table Mountain. Other good views are from Bonneville Dam and North Bonneville, Washington. Table Mountain is part of the massive Bonneville Landslide event which formed the Cascade Rapids, a major barrier to early travelers on the Columbia River. Lewis and Clark reached this area in October 1805 and had to portage around the rapids.

Lewis and Clark and Hamilton Mountain ...
Lewis and Clark's campsites of October 30 and 31, 1805, and their return on April 12, 1806, were on a Columbia River island in the vicinity of Ashes Lake, Washington. Table Mountain rises over the area.

Bonneville Landslide ...
Lewis and Clark reached the Table Mountain/Greenleaf Peak area on October 30, 1805, and set up camp just upstream of the "Lower Falls of the Columbia", across from today's Cascade Locks, Oregon. From this camp the men took two days to portage down through the the Cascade Rapids, an area created by the Table Mountain Landslide (Bonneville Landslide). This landslide is one of the greatest landslides along the Columbia River, diverting the river channel a mile, and creating the legend of the Bridge of the Gods.
