A colored photographic postcard. At the top left in red is the legend "Columbia River from St. Peter's Dome, Castle Rock in distance". In the foreground a man wearing a gray hat, red shirt, green-gold overalls, and black boots kneels at the top of a cliff on a formation identified as St. Peter's Dome. Below him is a steep but forested slope to the Columbia River below. At the bottom of the slope but further along the river is a segment of what appears to be a road or railroad right-of-way. Behind the man is a small waterfall. Beyond him is a view along the river, with Castle Rock half-obscured on the opposite shore, and mountains rising in the distance.
A black-and-white stereoscopic view. Printing on the cardboard mounting indicates it is number 1825 in the set of "Watkins' Pacific Coast" views of the western states. The caption of the photograph is "The Passage of the Dalles, Columbia River." From the rugged rocks of the near shore we look across foaming water to the an island, and beyond to the steep cliffs and high bluffs of the far shore.
