RESEARCHES AND EXPLORATIONS 



Every year the Institution engages, so far as its limited means 

 will permit, in explorations and field work, and a few of these ex- 

 peditions will be mentioned here briefly to indicate the nature of the 

 work accomplished. A number of other expeditions and researches 

 in various fields of science are described in the appendixes on the 

 National Museum, the Bureau of American Ethnology, the Astro- 

 physical Observatory, and the Freer Gallery of Art. In a few cases, 

 the entire expedition is financed and managed by the Institution, 

 but the small amovmt of income remaining each year, after the ad- 

 ministrative costs of carrying on the work of the Institution are met, 

 is soon exhausted, and thereafter it is only possible to cooperate in 

 various Avays in expeditions financed by other scientific institutions. 



GEOLOGICAL EXPLORATIONS IN THE CANADIAN ROCKIES 



During the summer and early fall of 1923, your Secretary con- 

 tinued his geological field work in the Canadian Rockies of Al- 

 berta and British Columbia. His main objective was to secure data 

 on the pre-Devonian strata from the Clearwater River southeast to 

 the Bow Valley and along the eastern side of the Columbia River 

 Valley. 



It was found that the Mons formation which was discovered on 

 the headwaters of the Saskatchewan River at Glacier Lake, extended 

 southwesterly on the western side of tlie Continental Divide in Brit- 

 ish Columbia to the southern end of the Stanford Range between 

 the Kootenay River and Columbia Lake, which is at the head of 

 the Great Columbia River, which here flows northwesterly in what 

 is known as the Rocky Mountain Trench. The valley of this latter 

 river was found to be largely underlain by the limestones and shales 

 of the Mons formation of the Ozarkian system, and the strata have 

 been upturned, faulted, and folded prior to the great pre-Glacial
