' 248 REPORT OF THE CALIFORNIA EARTHQUAKE COMMISSION. 
Just east of the station at Baden, where a creek crosses the county road, there were 
cracks in the filled soil, and there was also evidence that in this low ground the creek 
had flooded a distance of 100 feet on both sides of its usual course. At the time of the 
first visit, about 3 days after the shock, there was more water in the creek than there had 
been the previous week. At this same place, a steel water-main, supported on trestle- 
work, was wrenched so that it leaked badly. 
At Big Frawley Canyon a trestle carrying a 30-inch water-main was demolished. (See 
plate 100a.) 
The electric-car line that runs to South San Francisco turns a right angle at Baden, 
from northwest to northeast. The rails northwest and those northeast of the turn were 
both badly bent. On the northeast branch the rails were bent into a U-shape, the base 
of the U being to the northwest with a side thrust of about 2.5 feet. The rails on the 
northwest end of the line were bent into a V, with the base of the V pointing northeast, 
the lateral displacement being about 1.5 feet. These are about 60-lb. rails, and at the 
V-shaped bend mentioned the rails were broken in three places. 
South San Francisco. — 1.5 miles east of Baden, at South San Francisco, the intensity 
was considerably lower than at the previously mentioned places. Many chimneys fell, 
but no badly wrecked houses were seen. At this place the corner fell from a new brick 
building, under process of construction, and some of the other large brick buildings were 
slightly cracked. The damage at South San Francisco was not large, taken as a whole. 
(See plate 97B.) 
A little more than a mile east of the town, there are several tall brick stacks, none of 
which fell. Some were entirely uninjured and others slightly cracked, but only one, so 
far as known, was badly enough damaged to require rebuilding. The brick structures and 
stacks at the packing house did not suffer materially. 
Some of these buildings are almost on the San Bruno fault-line, and none of them are 
far from it, so that if there had been any movement along that line, these would certainly 
have suffered more. 
South San Francisco and the meat packers’ establishments are on a different geological 
foundation from the towns previously mentioned. These places rest almost directly 
upon the old Franciscan rocks, with only a thin layer of sand on top of them in places. 
This makes a much firmer foundation than is found at the other places, which are situated 
upon a considerable thickness of sand or gravel. 
The buckling of the tracks of the South San Francisco car line between the town and 
San Bruno Point, where the chimneys mentioned are located, is significant of the contrast 
in the intensity of the shock at the two places. The rails are bent and broken in a num- 
ber of places, where the track crosses the marsh between the two places. The differ- 
ence of intensity is striking when it is taken into consideration how close they are 
together. 
From South San Francisco to San Bruno, there is a line of big steel water-mains, sup- 
ported on a trestle frame, where it crosses the marsh. This line did not break, but was 
bent and twisted into S-shaped figures. 
North of San Bruno Point, at the Southern Pacific tunnel along the bay shore cut-off, 
no damage was done, except for the sliding and settling of the débris in the newly filled 
area. 
The cemeteries. —The San Bruno fault-line was followed all the way from South San 
Francisco to the cemeteries. There was absolutely nothing to indicate any movement 
along that line at the time of the earthquake. 
The cemeteries between Baden and Colma suffered very severely from the shock. 
It was estimated that in Holy Cross Cemetery (plate 968) over 75 per cent of all the monu- 
ments were either thrown down or twisted on their bases. Plate 974 shows a typical
