Castle Bock to the west. Down from the saddle between these runs 



Stevens Creek (Arroyo de San Jose de Cupertino) and down this 



creek went the earthquake crack, tearing up the road behind it. and 



throwing down landslides from every steep slope. Stevens Creek is 



made up from the union of two streams which meet from opposite 



directions. The crack descends the one and remounts impartially in 



the valley of the other. Both streams follow old earthquake tracks. 



Over another saddle the crack goes to Saratoga Creek. Across it and 



over another saddle it follows Campbell Creek, draining its reservoir. 



Thence it crosses obliquely the valley of Los Gatos Creek, over the hills 



of which Bret Harte wrote — 



The ridges 'round Los Gatos Creek

some ten acres of land was thrown in a great landslide. At the head 

 of the creek is the long tunnel which cuts under the saddle, from 

 Wright's to Laurel. This tunnel has been the source of endless 

 trouble since it was made, and for the reason that the rock in the 

 mountain through which it passes is made up of minute chips of rock. 

 No wonder, for the earthquake crack follows the mountain ridge, which 

 is here narrow and low. It cuts tunnel and railroad track at right 

 angles, and every earthquake disturbance is sure to make matters worse. 

 Already forty feet of crushed rock has fallen from above what was the
