STUDIES IN CAMBRIAN GEOLOGY AND PALEONTOLOGY. 
In my reports for the past two years reference has been made to 
studies of the older sedimentary rocks of the North American Conti- 
nent, which I have been carrying on as opportunity offered for more 
than twenty years. This work was continued in Montana and the 
Canadian Rockies during the field season of 1908. 
Outfitting at Belton, Mont., the last of June, 1908, the party pro- 
ceeded with saddle horses and pack mules north past Lake McDonald 
and on up the valley of the North Fork of the Flathead River to the 
Kintla lakes. From the Continental Divide northeast of Upper 
Kintla Lake beautiful views were obtained of the higher peaks, deep 
canyons, and snow fields north and south of the international bound- 
ary. Numerous photographs and notes on the geology were taken. 
The party crossed the forty-ninth parallel and moved north up the 
valley of the Flathead, in British Columbia, making several side 
excursions into the mountains. The farthest point reached toward 
the northeast was about 20 miles south of Crows Nest Pass. From 
there the route led along a trapper’s trail up Johnson Creek to the 
Continental Divide, thence to the town of Pincher Creek and south 
to Waterton Lake. An examination was made of the oil fields west 
of Waterton Lake on Cumberland Creek, which is about 15 miles 
north of the international boundary. From this point the party 
followed a trail along the western side of Waterton Lake and thence 
up Little Kootna Creek to the Continental Divide at the head of 
Mineral Creek, a tributary of McDonald Creek. A few days were 
spent in taking photographs and examining the geological structure 
in this vicinity before returning to Belton, on August 1, for supplies. 
A trip was next made by the way of Lake McDonald to Gunsight 
Pass on the Continental Divide, above Upper St. Mary Lake. But 
smoke from forest fires became so dense that the party returned to 
Belton and proceeded southward up the South Fork of the Flat- 
head River for about 100 miles. Examinations were made of Gordon 
Mountain and vicinity and during the return journey several geo- 
logical sections were examined along the western side of the Conti- 
nental Divide. Belton was again reached early in September and a 
trip was made to Marias Pass, which afforded a very fine view of 
the main range of the Rocky Mountains along the line of the Great 
Northern Railway. 
The scientific results of the 950-mile trip through the forests and 
on mountain trails will aid materially in the solution of several prob- 
lems connected with the stratigraphy and structure of the main ranges
