NO. 3 SMITHSONIAN EXPLORATIONS, I915 27 



The camp site in the Lamar Valley was one of unusual interest 

 and beauty (fig. 28). The high hills to the south show the rock- 

 cliffs containing silicified wood, calcite rosettes, and beautiful speci- 

 mens of chalcedony. A little way from the camp the party met 

 with a large herd of bison grazing freely in the broad open valley, 

 also herds of elk, bands of antelope, a few black bear, and an oc- 

 casional wolf.

 where there is a commingling of dry farming and irrigation. Richness of the 

 soil is indicated by shocks of wheat. 



On leaving the Park, after 675 miles of travel with the camp 

 outfit, the party proceeded down the West Gallatin River Canyon, 

 stopping to examine the section of Cambrian rocks at the mouth of 

 Squaw Creek (fig. 36). The next permanent camp was made 

 in Deep Creek Canyon, 17 miles east of Townsend, Montana, where 

 the extensive pre-Cambrian sections of the Big Belt Mountains are 

 beautifully shown. About two tons of pre-Cambrian specimens were 

 collected in this vicinity, before the storms of late September closed 

 the season's field-work.
