and mammal skins was also made. In addition to these, miscellaneous 

 specimens were obtained including insects, reptiles etc. Besides the 

 actual collecting an important part of the work was the preparation of 

 notes on such points as topography, stratigraphy, distribution of birds, 

 etc. Also a considerable number of photographs were taken showing 

 the character of the country and other points of interest. 



Map Showing Route of the Expedition 



On the above map the route of the expedition is indicated by the heavy broken line. 

 Near Lyons about 15 miles north of Boulder plant collections were made and on the 

 Little Thompson Creek a few miles farther on a small collection of fossils. On Fossil 

 Creek, near Trilby siding, a few miles south of Fort CoUins, the expedition made a halt 

 of five days and collected considerable fossil and plant material, as well as some birds 

 and mammals. From the exposures on the south side of the Cache la Poudre River 

 near Windsor, an interesting collection of fossils was made. Near the Davis ranch, a 

 few miles east of Grover, a few vertebrate remains were collected from the Tertiary 

 exposures. The plant collections described in another part of this paper were made in 

 this locality. Some valuable fossil material was obtained along Crow Creek, between 

 this place and Greeley and also near the mouths of the Thompson and St. Vrain Creeks 

 southwest of Greeley. 



An important part of the work of the expedition was done in the 

 northern part of Weld County, on the borders of the high plains, so a 

 brief account of the topography and climatic conditions of this region 

 may be of interest. Extending in an east and west direction, near the
