Unidentified construction project on Mount Wilson. The ten (10) visible construction workers are also unidentified. Most of the men are carrying a very large wooden box or container; the rest of the men are standing by. Some of the men are wearing coveralls, and some are wearing hats. Some kind of a hole or ditch is visible in the lower right-hand corner of the photograph.
