 were noted by Professor Lawson :

DESCRIPTION OF THE TYPE LOCALITY 



Location and Topography. — The territory over which the ob- 

 servations on the typical Monterey were extended comprises an 

 area about four miles square between Monterey Bay and the 

 valley of the Carmelo River, and lying principally east of the 

 main coast road leading from Monterey to Carmel-by-the-Sea. A 

 small area occurs in the higher hills west of this road. Several 

 short excursions were made beyond the limits of this territory, 

 but they have no direct bearing upon the results. This localitv 

 lies at the north extremity of the Santa Lucia Range, and while 

 it may be easily separated physiographically from the region to 

 the south of the Carmelo River valley, it must, nevertheless, be 

 considered a part of the range. The physical features show 

 well-rounded hills and flat-topped ridges whose flanks are dis- 

 sected by numerous streams and ravines. In no case does the 

 elevation exceed eleven hundred feet. Prom Point Pinos the 

 hills rise abruptly to the southward, attaining an elevation of 

 approximately eight hundred feet two miles southwest of Mon- 

 terey, where they swing to the eastward, forming a crescent- 

 shaped chain around the town. 



Stratigraphy. — The stratigraphic relations of the Monterey 

 series are very simple. At several localities along its western 

 border it may be observed resting almost horizontally upon the 

 eroded surface of the Santa Lucia Granite. On the northern and 

 eastern boundaries the shale passes beneath the Recent or terrace 

 accumulations which flank the hills in the vicinity of Monterey
