Elevated view north on Powell from across Market & Powell, a cable car on the tuntable. (litho view of ta Zan Stark photo) [This shows the turntable at the junction of Market and Powell Streets, where Gripman and Conductor turn the little car about for the return journey up the hills. San Francisco is a city of hills and over many of them climb the little cable crs. Magnificent vistas are obtainable from the open-air seats of the jaunty cable cars.]
