Milwaukee, Milwaukee County. July, 1968. Altitude c. 1,500 ft. The three domes of the Mitchell Park Conservatory are centered in this low oblique photograph to the north. The brown-colored Menomonee River makes a northward bend at top left, and the Layton Avenue (Highway 57, 27th Street) viaduct crosses the river valley and railroad tracks, also at left. The domes house rainforest, desert, and seasonal botanical exhibits.
