Considers Bridger and "Washakie" rocks largely tufls 

 modified by slight transportation. The older Eocene rocks 

 are considered more strictly sedimentary.

 Rept., vol. 1, 803 pp., 21 pis., 12 maps, 1878. 



Gives the name "Vermilion Creek" to the Wasatch beds of 

 southern Wyoming; considers them as lowest Eocene and 

 unconformable with the overlying Green Eiver beds. The 

 name "Uinta group" is given to the uppermost 400 feet of the 

 sediments in the vallej' of White River; considered to lie un- 

 cnnformably on lower beds and to represent uppermost Eocene 

 Mammals collected by Marsh are listed. Area is mapped, 

 and relationships of Bridger with other Eocene deposits of the 

 basin are set forth.

 Treats of the Big Uorn Basin Wasatch; divides the beds into 

 three faunal levels, lists fossils from each level, and gives sec- 

 tions. The Wasatch is considered a flood-plain deposit, the 

 upper 1,000 feet of which appear to overlap in time the base 

 of the Wind River.
