268 REPORT OF THE CALIFORNIA EARTHQUAKE COMMISSION. 
In the town of Boulder Creek, all chimneys were down except those on some 1-story 
cottages; these were cracked, however. People generally ran out-of-doors, but were not 
as a rule very badly frightened; some even stayed inside until they had drest. Water- 
pipes were not broken, but some plaster had fallen, and plaster was cracked everywhere. 
Mr. Bloom, owner of a sawmill at the edge of the Big Basin, reports that the shock was 
less severe in the Big Basin region than at Boulder Creek; that there were no landslides 
on the road between the two places; and that, tho he had been nearly to the summit on 
the day of the earthquake, he had seen only one crack where the earth had started to slide. 
(R. Collom.)— At Boulder Creek, on the east side of the stream, a small hill of about 
150 feet elevation rises rather abruptly. Its sides are thickly covered with small trees 
and brush. Near the top, a large portion of the surface soil had been shaken loose, and 
had slid to the level of the creek, carrying trees with it. 
At Ben Lomond no fissures nor other such evidences of the earthquake were to be seen. 
Inquiry showed this condition to continue in the country about the town. Broken 
chimneys were the only evidence. The inhabitants of Ben Lomond report several slight 
shocks during the night of April 21-22, 1906. 
(B. Bryan.) —Going north from the village of Boulder Creek along the San Lorenzo 
River, only small wooden houses were seen, all with chimneys standing. There were 
few evidences of the force of the shock, except fallen redwood trees. Three dead red- 
woods had been snapt off from 30 to 50 feet above the ground; and farther on two more 
were noticed, one having broken and the other having been uprooted. A man who was 
at the sawmill, 8 miles north of Boulder Creek, at the time of the earthquake, stated that 
a few trees were torn up by the roots. Cordwood had been thrown down in several in- 
stances along here. A small landslide had moved across the road (at 44, map No. 22), 
which 20 men spent one and a half days clearing away. In the gulch the tops of a 
number of redwood trees had been broken off from 50 to 100 feet from the ground, the 
diameters at the point of fracture measuring from 10 to 14 inches. Up the road to the 
summit of Castle Rock Ridge no slides nor cracks were observed. 
On Boulder Creek, coming southeast down the China Grade, the shock was strong, but 
apparently not so severe as along the San Lorenzo River. The people were badly fright- 
ened by the shaking, however. One man reported that no redwood trees fell and that 
only a few dead limbs were broken off. Near the junction of the first road leading from 
Boulder Creek into the Big Basin, an old landslide which covered about 2 or 3 acres, 
dating back to the previous winter, had been widened by the shock and its direction had 
changed. Only a couple of hundred yards farther down the road, some stacks of smooth 
split redwood logs (cordwood size) had not been shaken down. 
A small earthslide had started (at 45, map No. 22), and a crack, perhaps due to the 
same slide, was noticed. For the next mile or so southeast, there was a considerable 
amount of cordwood along the road, none of which was disarranged by the shock; and 
no trees nor dead limbs had fallen. In the houses between this place (45, map No. 22) 
and the sawmill (at 46, map No. 22), the evidences of damage were more serious. At 
this first place visited no damage was done; people were awakened but did not get up; 
no trees nor limbs had fallen. At the next place, 1 mile southeast, people ran from the 
house during the shake and attempted to remove a sick man. Small objects were thrown 
down and a pendulum clock was stopt. At the house just southeast of the mill, the inside 
furniture was overturned, the stove moved, and the terra-cotta chimney split and fell; 
while branches were broken from redwood trees near the house. At the mill the same 
effects were noted, and others as well; tops of live trees, from 6 to 8 inches in diameter 
at the fracture, were broken off. From the point (46, map No. 22) down to the road 
leading to Bloom’s Mill, 1 mile south of the point (45, map No. 22), the intensity 
seemed to have been less. A water-tank beside the road was quite unhurt; houses were
