Life of Upper Lake Region. 143 



Miocene deposits are disturbed in Oregon. 

 This deposit is not disturbed; it must, there- 

 fore, have been deposited after the disturb- 

 ance at the close of the Miocene, which would 

 make it Pliocene. But more; a few years 

 ago this rock was extensively used for build- 

 ing purposes in The Dalles. In one of the 

 building blocks taken from the quarry was 

 found a well defined fragment of a metacarpal 

 bone of a camel, and the camel in Oregon 

 marks the Pliocene. This metacarpal of the 

 camefl became of added interest when a few 

 years since a fragment of a very small radius 

 was found, which came into the hands of the 

 writer. This fossil was found among other 

 bones, two or three miles from The Dalles, 

 by men searching for gypsum in an eastern 

 extension of the same gray sandstone. The 

 animal to which it belonged was an Auchenia 

 of the camel family and represents an animal 

 perhaps twenty-five to thirty inches in height. 

 Years ago the writer designated the group 

 of rocks to which this gray sandstone belongs 

 as The Dalles group and Pliocene.
