at sunset. A walk or drive to Redwood Peak takes the visitor past 

 the former home of Joaquin Miller, author of '^ Songs of the Sierras" 

 and many other famihar poems, and affords equally fine views. 



Leaving the station at Sixteenth Street, the train skirts the west 

 side of the city and runs out on a pier or mole 1^ miles long, from 

 which the rest of the journey must be made on the San Francisco 

 ferries. The distance across the bay is 4 miles, and the trip is made 

 in about 20 minutes. In crossing the bay the traveler sees Goal 

 (or Yerba Buena), Alcatraz, and Angol islands to the right, Alarin 

 Peninsula beyond them, and the Golden Gate opening to the west of 

 Alcatraz. 



Goat Island lies close to the ferr}^ course across the bay* Like most 

 of the other islands in the bay, it is owned by the Government. On 

 the nearest point there is a lighthouse station, and below it the 

 rocky cliff is painted white to the water's edge. Just to the right of 

 this is the supply station for the lighthouses of the whole coast from 

 Seattle to San Dieo:o. Behind this station is the United States naval

has an interesting geologic story. The great depression 

 lies was once a valley formed by the subsidence of a t)lock ot the 

 earth's crust— m other words, the valley orighiated by faulting. The 

 uplifted blocks on each side of it have been so carved and worn by 

 erosion that their blocklike form has long been lost. Erosion also has 

 modified the original valley by supplying the streams with gravel and 

 sand to be carried into it and there in part deposited. The moun- 

 tains have been worn down and the vaUey has been partly fiUed. 

 Possibly the valley at one time drained out to the south. However 

 that may be, at a later stage in its history it drained to the west
