rocks — shales, sandstones, and conglomerates of the lower part of the 

 Monterey group — cover a wide area. They are bent into anticlines 

 and synelines and are covered by younger shales of the Monterey 

 group and in part also by younger Miocene and Pliocene sediments. 

 The rocks of the lower slopes near which the train passes just beyond 

 Chittenden, on the right, are Pliocene (Merced formation). About 

 2^ miles from Chittenden, near milepost 88, San Benito River and 

 Llagas Creek join to form Pajaro River,

 Across the valley in the distance can be seen Pacheco (pa-chay'co), 

 Antuuony, St. Anna, Mariposa (the highest), and other peaks of the 

 Mount Hamilton division of the Diablo Range, which separates the 

 Santa Clara Valley from the San Joaquin Valley. 



The Santa Clara Valley extends from San Francisco Bay southeast- 

 ward to and beyond San Benito, a distance of nearly 100 miles. It 

 has a notable peculiarity in that it is divided transversely by a scarcely 

 noticeable soil-covered divide. The southern portion is drained by 

 Pajaro River, but the northern portion drains through Coyote River
