That there is one deep
quarry.
The joints
in that granite
have sure relieved a lot of
stress.
Some of the joints turn into faults,
says Phil.
The uncomformity between the Aromas
Sands and the granitic rocks is SPECTACULARLY exposed in the
quarry.
And the San Andreas Fault
is never far away.
Hollister sidewalks are very squiggly.
From Vista Hill Park, you can see the
Calaveras Fault to the North, and the
Calaveras Fault to the South. Can you see where the fault cut through
the buildings below?
In San Juan Batista, where frisbees get thrown
across plate boundaries, the mission is rising up to the heavens
because the fault slip rate is faster to the south than to the north.
Because of the differential slip rates, comression occurs between the two
segments, which causes the uplift.
Jim talks about coastal processes at
Moss Landing Spit, where there are pretty beaches
and the Monterey Canyon
You can practically put a dime on the fault.
Those rounded cobbles on Vista Hill
suggest that a high-energy stream once came through here. But why do the
hills remain lined up along the Calaveras Fault?
Tina and Rebecca listen intently.
So sad, the fieldtrip has
come to an end.
What do YOU THINK about the field trip?
