Baker Iron Works and Capitol Milling from Yale Street above Calvary Cemetery, William Henry Jackson, 1888
Also shown a good shot of the enormous Union Warehouse at Naud Junction and an as yet unpaved Bruno Street.
Also missing is McCarey's Pavilion or Naud Junction Arena which would be to the left of the Union Warehouse.
Notice the relative absence of rails. This view will ultimately be loaded with rails leading into and out of the 'Cornfield' just out of-frame to the left.
