30 SMITHSONIAN INSTITUTION 



About the middle of June I returned to the Grand Canyon, where 

 the Park Service again kindly put at my disposal equipment and ani- 

 mals. I now had the pleasure of studying the well exposed rocks along 

 the Kaibab and Bright Angel Trails. This work was done in conjunc- 

 tion with Edwin McKee, the efficient Park Naturalist, who is carrying 

 forward investigations that will contribute much to our deficient 

 knowledge of Grand Canyon geology. 



My journey to Salt Lake City was made via San Francisco, where 

 I examined certain type specimens in the University of California 

 collections. 



At Salt Lake City, I was joined by Dr. Riuji Endo of Mukden, 

 Manchuria, who was to accompany me during the remainder of the 

 season. After organizing for camping, we went to Delta, Utah, pre- 

 paratory to a trip into the Utah desert. Here we were joined by 

 Mr. Frank Beckwith, editor of the local paper, who is greatly inter- 

 ested in the geology of his country. At this point the unusual weather 

 of the season began to impress itself upon us. During May and June 

 rains fell when none were due, but the departure from normal was 

 not so great as to attract more than passing notice. The past several 

 years had been dry throughout all the west and consequently rain was 

 greatly desired. At Delta much rejoicing was apparent when heavy 

 rain began to fall particularly on the watersheds that fed the irriga- 

 tion canals. Cloudy, threatening weather attended our departure into 

 the desert, making the temperatures very comfortable where we ex- 

 pected to experience the usual burning heat. 



In the House Range Mr. Beckwith took us to Antelope Springs, a 

 small permanent flow of water near the fossiliferous outcrops studied 

 many years ago by Doctor Walcott. After reviewing these sections 

 we crossed the range by Marjum Pass and then followed the usual 

 rough desert track that by courtesy is called a road. Travel was 

 exceedingly rough as heavy showers had either washed ridges of dirt 

 and stones across the road or cut parallel grooves. 



Saturday evening we reached Ibex in the Confusion Range. Mr. 

 Beckwith introduced us to Jack Watson who has lived there for many 

 years, mostly alone. No springs or streams occur here, as the nearby 

 ranges do not attain the height of 10,000 feet necessary to cause 

 sufficient precipitation to insure springs. Consequently Mr. Watson 

 must depend solely on rain water captured in tanks formed by dams 

 across gullies. When we arrived we found that he had no water left 

 in his tanks, since the regular spring showers had not materialized, nor 

 had the rains that began ten days previously in the higher mountains 

 to the east yet spread this far into the desert. He was particularly
