Basin, Utah. 



1. Conglomerate and coarse light sandstone. Shi- 



narnmp conglomerate.

 actually traced into the Moenkopi formation of the Nav- 

 ajo Reservation, I think the correlation is amply war- 

 ranted on the ground of position in the sequence, for they 

 underlie the Shinarump conglomerate, which is an excel-
