540 HISTORY OF PASADENA. 



It will be noticed that he ignored the old established name "Sierra 

 Madre," and called our local range the San Gabriel Mountains, of which he 

 says further : 



" The San Gabriel range, as we denominate it, is a vast mass of moun- 

 tains extending from the Cajon pass on the east, and joining with the Santa 

 Monica and Santa Susanna ranges on the west. It is fully 60 miles long, 

 and from 20 to 25 miles broad from north to south. * * San Gabriel is 

 the designation of the principal canyon by which the chain is traversed, 

 and of the only stream of any size which heads in it." 



He gives some account of the range east of the San Gabriel river, but 

 nothing wedt of it, except to mention incidentally that a little gold washing 

 was carried on near the entrance of Santa Anita canyon or its outwash into 

 the San Gabriel river. Further on he says again : 



" In the vicinity of lyOS Angeles the rocks exposed are chiefly argilla- 

 ceous, shaly sandstones, with dark colored shales interstratified ; these 

 rocks are highly bituminous, and have generally a southerly dip. In the 

 Arroyo Seco, which comes into the Los Angeles river from the northeast, 

 these strata are well displayed . ' ' 



The above extracts show the nearest nips of geological investigation 

 which Pasadena and her contiguous mountains have ever received from any 

 ofiicial source, so far as I have been able to learn. But in 1883, by the 

 kindness of Prof. Lowe, I was enabled to spend nearly three months in the 

 Mount Lowe section of our local mountains ; and two years before this I 

 had spent six weeks in the Mount Wilson section and in traversing the 

 West San Gabriel and the Arroyo Seco canyons. From data gathered in 

 these and other previous researches in Pasadenaland, I prepared a Geologi- 

 cal Report, and read it before the Science Association of Southern California 

 in Los Angeles, at its meeting in January, 1894; and from that report I here 

 make some extracts : 



WHAT GEOLOGICAL AGE. 



' ' Our accredited authorities all agree that the Pacific coast mountains 

 of California belong to the Tertiary Age, which means that in a geological 

 sense they are of comparatively recent origin. The Tertiary Age was the 

 first period in geological time, when the earth had become fitted to sustain 

 such higher types of both vegetable and animal kind as hold place today. 

 In the Zoic calendar of creation it is known also as the "Age of Mammals," 

 evolved out of the "Age of Reptiles " next below, and in turn evolving the 

 "Age of Man " next above, or the geological age in which we are now liv- 

 ing, and in our turn evolving the "Age of Angels" or spiritual beings.

 were three others, the " Mosaic Calendar," the "Psychic Calendar," and the "Synoptic Calendar of 

 Creation," showing the steps and stages of creational progress on four different lines of inquiry, under 

 the law of evolution — all prepared by Dr. Reid to illustrate topical addresses before the State Academy 

 of Sciences at Des Moines, Iowa, and public lectures thereafter at various places in Iowa, Minnesota, 

 Nebraska and Missouri.
