At the westernborder of this county, a spur takes off to the southeast, Casitas beingat or near the pivotal point, and continues as far as Santa Paula Creek,where it again merges with the main range. Ojai Valley, lying eastand west between these two ranges, is distinctly a valley of formation,that is, its origin is due to earth movements, while the narrow valleys,hardly more than canons, of Ventura River and Santa Paula Creek,are plainly eroded channels, cutting as they do across the strike of theformation.

Ojai Valley is a rather flat table-land, lying some seven hundred feetabove sea level, and extending to the west beyond the bounds of town-ship 4-23. At this point the width is some three miles, at Nordhoffperhaps one and one half miles, and some two miles to the east of thistown the lower valley terminates in a low ridge, ranging from north-west to southeast, and lying between San Antone Creek and LyonCreek. This is a well-watered, fertile, and prosperous valley, consistingof pasture lands studded with oaks, and of highly cultivated fields andorchards. Upper Ojai Valley is separated from the lower valley by the ridgejust mentioned (which is, indeed, hardly noticeable at its eastern side),and lies much higher, being from fourteen Hundred to fifteen hundredfeet above sea-level.
