beds and the Fox Hills in Converse County cannot be accepted, contrary to 
other evidence, as proving the former to have been deposited in the epoch next 
succeeding the Fox Hills. 
It is apparent from what has been quoted above that Dr. 
Stanton, when he went with Weed in 1894 from Fort Benton to the 
Judith River, found the Judith River beds in the type region in 
their normal position and that he was correct in assigning them to 
the stratigraphic positionimmediately overlying the Montana forma- 
tion which, in its upper portions, contained a Fort Pierre and Fox 
Hills fauna. It was only when he got into the disturbed region 
near Havre, Mont., that he found marine Cretaceous shales over- 
lying what he called ‘‘ Judith River beds” and his explanation, that 
their apparent position when so found was due to faulting, was 
probably also correct.‘ Of course these beds exposed at Havre 
were not the real Judith River but the true Belly River series which 
normally underlies the Pierre as exposed in Canada north of this 
region. These beds were again examined by Dr. Stanton when 
with Hatcher in 1903. Their field studies were begun at this 
point, Milk River at Havre, and they 
examined the excellent exposures along that stream to the international 
boundary, and beyond to Pendant d’Oreille Police Barracks, which is near one 
of Dawson’s described localities, where the base of the Belly River beds is seen 
resting on the marine ‘‘lower dark shales.” This is near Lake Pakowki of 
the maps, locally known as ‘‘Badwater Lake.’ We also examined the ex- 
posures of upper Belly River beds showing contact with the overlying “Pierre 
shales”? on Sage Creek, Canada, as described by Dawson and McConnell, and 
continued our observations as far north as the Cypress Hills, where the top of 
the overlying marine Cretaceous is seen. Passing down Milk River below and 
around the eastern end of the Bearpaw Mountains to Cow Creek and the 
Missouri River at Cow Island and thence up Dog Creek, Judith, and Eagle 
Creek, Mont., we have studied the typical areas of the Judith River beds 
described by Meek and Hayden, and of the Eagle formation described by 
We have become fully convinced that the Belly River beds are identical 
with the Judith River beds, as Dawson long ago suggested. Our conclusion 
« Dr. Stanton’s exact words are as follows: ‘‘When a few days later the overlying 
marine cretaceous shales were seen in contact with upturned Judith River beds near 
Havre, Montana, their apparent position was supposed to be due to faulting of which 
there was abundant evidence in the neighborhood.”—U.S. Geol. Surv. Bull., No. 257,
