Carrizo Plain National Monument
Carrizo Plain National Monument is the largest native grassland remaining in
California. Here you can witness the San Andreas Fault as it is cutting through
the valley. another prominent feature on the monument include the white alkali
flats of Soda Lake and the vast open grasslands, after rainy winter, wildflowers
carpet the valley floor.
: The Monument is located about 160 miles north of Los Angeles, 260 miles south
of San Francisco in southeastern San Luis Obispo County.

43 miles west of Bowerbank at hwy 5.

this entrance start with an old paved section later transform into 18 miles long dirt road (do not try to use it
after ran when it is nuddy).
Spring (the month of April and May) is an ideal time to visit, as the Carrizo
Plain is one of the best wildflower destinations in the state. At summer this
is mainly dry open grass land without any water in the lakes.

within the Monument have an unimproved dirt road. When dry most of the valley
main and marked roads are good for any vehicles, mountain road may need 4x4.
Unpaved road become impassable to cross during periods of rain; roads often take weeks

the spring, when wildflower blooms. This is very secluded place with almost no
other visitors, interesting geological thing to see. Out of the main roads, far
away destination but I recommend visiting here.
Carrizo Plain National Monument located in southeastern San Luis Obispo County.
It spread over 246,812-acre and it is the largest native grassland remaining in
California. The Carrizo Plain Natural Area became a National Monument in
January 2001 by presidential proclamation.
Carrizo Plain is a large enclosed grassland plain, approximately 50 miles long
and up to 15 miles across, the valley is located between Caliente Mountain Ridge
in the south west to Temblor mountain range on the north east. The San Andreas
Fault is cutting through the valley. When visiting Wallace Creek Interpretive Trail,
you can actually see how this fault changed the landscape.
features on the monument include the white alkali flats of Soda Lake and the vast
open grasslands. When conditions are right, after rainy winter, wildflowers carpet
the valley floor.
Lake, normally a dry lakebed, is the largest remaining natural alkali wetland
in southern California and the only closed basin (no water outlet) within the
coastal mountains. Because there is not water outlet Soda Lake concentrates
salts as water evaporates, leaving white deposits of sulfates and carbonates.

creek flows out of the Temblor Range and at San Andreas Fault it takes 90
degree to the right and after another 150m it is going back to the old flow
path to the left. That's how much a series of quakes has moved the fault over
the past 3,800 years.

creek a full 30 feet from its previous location.
