The volcanic rocks of the Conejo Formation underlies much of the surrounding watersheds. The younger Tertiary sedimentary Modelo and Upper Topanga Formations flank the Conejo to the north and south. On the north slope of the Santa Monica Mountains where the Arroyo Conejo and Thousand Oaks are located, the Tertiary formations are gently folded.

Arroyos are incised channel systems (fig. 1), such as the Chaco Arroyo studied by Love (1983), that carry large volumes of sediment during ephemeral or intermittent flows.

Rock that is easily eroded is one of the essential ingredients of arroyo formation. In semi-arid climates, where there is little vegetation on the landscape, the abundant erosion products are washed downhill, where they accumulate in alluvial fans. This fan, composed of fine-grained sediment, has a small arroyo incised into it.The velocities of elastic waves (P and S) generally increase with depth in the earth.

Arroyos are the vertical-walled, flat-floored channels of ephemeral streams of the semiarid Southwest formed both since 1880 and during some past ages. Arroyo-cutting takes place because the plant and soil mantle is poor or destroyed and permits the water of violent showers to run off too fast and form torrents in trails, ruts, ditches, and stream beds. …

The term current pore-size distribution means that the size of the pores is being updated as the soil deforms.

Arroyo-cutting takes place because the plant and soil mantle is poor or destroyed and permits the water of violent showers to run off too fast and form torrents in trails, ruts, ditches, and stream beds. Filling occurs when the runoff is slowed by vegetation so that it drops its load.Six warrior stelae from central Iberia (Toledo, Spain) were studied using different geological techniques to discriminate their potential source materials and evaluate the displacement suffered from the quarry sites to their final location.
