Carrizo Plains The Carrizo Plain was named a National Monument by President Clinton in January, 2001, to preserbe the unique ecosystem. Carrizo is located near the southern end of the coastal mountains, between the Temblor Range and the Caliente Range. The highlights are the Soda Lake, a dried lakebed, Painted Rock, and Wallace Creek. The San Andreas Fault runs along the northeastern edge at the bast of the Temblor Range, and provides some interesting results.These two pictures show the expanse of grassland in the Carrizo Plain, looking north and east from the parking lot for the Painted Rock trail, across the plains towards the Soda Lake and Temblor Range. |

The Painted Rock The Painted Rock is reputed to have mystical signifigance for the native Americans who inhabited the Carrizo Plain before the arrival of Europeans. |

Open Space These next three pictures show the view across the plain to the Temblor Range. In the second, we have another rock in the foreground. This rock, and Painted Rock, are at the base of the Caliente Range. |

The Painted Rock The Painted Rock stands out in a plain of grass. It gets fairly weather-beaten. |

Whitewash If you look closely, you can see some whitewash. This suggests that this hole in the rock may have been used as a perch for a raptor looking to feed, or maybe even a nest. Identifying these whitewashes is a good trick for finding perched raptors, whether on cliffs, or on the Golden Gate Bridge. |

View from the Rock Another look across the plain. There aren't any looks across the plain to the Caliente Range because of the lighting. |
 |
The Rock Another image of the rock. |
 |
View from Inside the Rock There was a hollow inside the rock, from which we can look out towards the Soda Lake. |
 |
Petroglyphs The native Americans painted petroglyphs in the rocks. |

A Crow's Nest A crow nested here. |

Wallace Creek On the far side of the plain is Wallace Creek. This creek crosses the San Andreas Fault, resulting in a break. The first picture, taken from the Pacific Plate, looks up towards the source of the creek (currently dry.) It looks unremarkable. The second picture is taken from a point on the San Andreas Fault, looking northwest. When the creek reaches the fault, it is immediately turned to the northwest and follows the fault for approximately 150 feet, and then it makes a second 90 degree break to the southwest. About 6000 years ago, Wallace Creek was straight across the fault, but successive earthquakes and other slippage has resulted in these right angles. The third picture, taken from the North American Plate, shows the angles more clearly. |
