S^riTTISOXIAN EXPI.ORATIONS. 102/ TQ 



We left Washington on July 21 and met Dr. Ijassler in Prove, 

 Utah, July 29, having covered the 2,250 miles in eight days, one of 

 which was spent in a repair sho]), a delay made necessary hy a plains- 

 man, fearful of the outer edge of a winding mountain road, coming 

 up on the wrong side of the road. X"o other means of transportation 

 than hy motor can give one such an intimate view of our country nor 

 so impress on the mind its immensity and the extent of its resources. 



After securing the portion of the camp outfit that had heen left 

 in storage at Provo, we moved on to Salt Lake City where a confer- 

 ence with the local geologists was held concerning their more recent 

 discoveries and advice as to desirable places to visit was obtained. 

 Here Dr. Bassler was able to arrange for an important collection of 

 Permian fossils, which has since been received at the Museum. 



After briefly studying the Wasatch Mountains and traversing 

 Yellowstone Park, the sections in the mountains immediately to the 

 north were examined, the one along Newland Creek, Meagher County, 

 Montana, being studied in some detail. Then since our route led by 

 the Little Belt Mountains, stops were made here to study their Cam- 

 brian strata. 



The main objective of the summer's work was the general region 

 of the Bow Valley, Canadian Rocky Mountains, to the north and 

 west of Banff, Alberta. The first cam]i was made on Vermilion Pass 

 on the Banft'-Windermere road, in which vicinity a number of sec- 

 tions were studied. It was hoped that as a side issue of the season's 

 work the vexing question as to the extract stratigraphic boundary 

 between the Lower and Middle Cambrian could be determined, and 

 here in Vermilion Pass there seemed to be a chance for finding the 

 necessary data. However, the time and equipment at our disposal did 

 not permit us to reach a sufficient number of points to enable us to 

 decide the question. A survey of the interesting and important sec- 

 tion in the Saw1)ack Range was next made with the idea of verifying 

 the presence of certain Cambrian and Ozarkian formations. 



Several days were spent in the vicinity of Lake Louise where 

 many of the best Cambrian sections are located. Camp was then 

 moved into the Kicking Horse Canyon near Field, where are located 

 two remarkable fossil localities : one on Mt. Stephen, which has 

 been known for more than 50 years ; and the other above Burgess 

 Pass, where Dr. Walcott discovered the most important Cambrian 

 fauna ever found. We continued down the Kicking Llorse Ri\'er 

 to Golden, reviewing the great sections exposed along the gorge of 

 that river.
