Pillars of Hercules on the Columbia River
Pillars of Hercules on the Columbia River
TitlePillars of Hercules on the Columbia River
DescriptionColored image. Close-in view of the Pillars of Hercules rock formation as seen from the vista of the Columbia River, facing the riverbank. In the foreground is the riverbank where it touches upon a sandy beach. There are two pillars at the riverbank and two that can be seen inland (there may be more), with the beach situated between the pairs. Upon the beach are remnants of trees: stumps, branches and logs, along with a number of wired utility poles. Behind the riverbank is an elevated, level area that may be a road. There are equally distanced posts outlining the level area. In the far background are rising hills covered with fir trees. The pillars are substantial in height; each has patches of green moss over a predominantly gray surface.
