Looking north from south end of Snow telescope construction site, Mount Wilson Observatory. Four (4) unidentified construction workers are seen; the head of one is just visible behind a pile of dirt; two are standing around a cement mixing trough near a wheelbarrow, and the fourth is to the right in the distance. Sandbags are near the cement trough. Trees and shrubs are in the surrounding area.
