A real photographic postcard of San Dimas Canyon Dam, California, 5 March 1929. A black and white photo of a cement wall and walkway built across the narrow canyon. There is water creating a lake on the camera side and what appears to be a road in the background. The bottom left is labeled "San Dimas Canyon Dam / Near Wolfskill Falls Camp / Frashers Foto - Pomona." With delamination of the top left corner, abrasion on the top and right edge, and stains on the reverse, the object is in good condition overall.
